I2S out issues with the A8

Ok Dr,Keith. How did I know you would step out of the office, most things in the world today are absolutely unpredictable but well if I were playing the lottery, I could always count on you 100% that’s for damn sure to imply some type of idiotic statement, I guarantee that they say down south ,
I guarantee,
Dope on a Rope

 

Mister L, Nutul and Keith are the best... at the end of a 'being valuable scale'

Most likely I will be able to answer my question by myself in a more or less closer future.

 

Oh My word Jokerk, are you actually and sincerely telling me that you were going to avoid the Advice of true professionals engineers programmers my word what has happened to you? I would recommend and highly advise that you seek further advice and knowledge before proceeding. Whatever came over you my word, what is the High End Audio world coming to, I even quoted the word of a certified engineer that was indeed the head of several high-end organizations and it is still left. Open the question you better think about what you’re doing before you make any changes I think you’ll regret it. Good luck.

Have a wonderful weekend buddy

 

Biamp don't really understand what you want to tell me. The good thing about my situation is, I am thinking about a second system anyway. Thus if I purchase a T8 and a LAiV Harmony uDAC, I will use the A8 in my second system. So all easy.

 

Jokerk, sorry for the unrecognizable humor for lack a better terminology, Nothing you need to know right now I am sitting in my truck walking. My dog, I guess being across the big pond would absolutely make somewhat of a humorous Understandable indifference
I was just trying to be a little funny, not towards yourself towards the situation at hand.
I am in agreement with yourself. It is your equipment and whatever you believe to work best well that’s best for you and that’s all that matters but thank you for your post and your reply. That’s a very excellent idea. I think you do have if you want the A8 currently speaking

And still enjoy it and haven’t had any problems or issues, if I was able to, I agree with you 100% I would keep it. I think it may turn out to be a good move and you’ll also always have a back up and something that you can refer back to as a comparator

But again, please have a wonderful and safe weekend. Enjoy the music

 

Thanks biamp, that sounds great. Have a wonderful rest of the weekend.

 

So be it. Hope you succeed without you and your money being soon separated.

 

Nutul , may I ask you a Question, I cannot be certain, seriously speaking, have you ever heard of Teddy Pardo, High End Audio. Somewhat of a leading provider
Of high-quality linear power supplies for audio equipment, I’m asking you for a very good and absolute reason, You may tell me to go jump in the river ?
However, before I proceed any further, I was wondering, if perhaps you may answer my question, and if you possibly could, do you think it may be possible
to give overall opinion, in general, just a thought, as it would be useless for me to go any further without a reasonable response from yourself,
Thank you. I would greatly appreciate it, if you could give thought or opinion in overall thought of , in which I will know which way to proceed
This is a very valid and honest question again if you would care to respond, please have an enjoyable evening
If not I most certainly understand.

 

Yes, I have.
Wanna hear my unbiased response? Unless the PS unit of your device is of very poor design; you do not need to replace it. Let alone with one that provides you with the very same amount of needed power, same low-level ripple at a few uV, but costs in the hundreds...
This I say.

 

Nutul thank you, I am very happy and delighted that you also answered my question, but that only answered my question the way
That you answered it and being very descriptive in nature, and very much, so from a technical aspect of somewhat of
a bit of power supply information itself, again I thank you here is my reason for asking you. What I am about to say or explain
to yourself is 100% true and factual, I will supply all information along with this reply phone number information verification
on someone as follows, Here’s why I asked !

it is in my nature to be very precise,, I do not have an exact date, but the timeframe within itself and standing, I believe would suffice
I had telephoned, Teddy Pardos, High End Audio company we have approximately three months ago, that would be standing approximately
12 weeks at subtract by one, trying to be as accurate as possible,. in conversation with him about an entirely different audio device
And power supply upgrade, Throughout our ongoing conversation, I had mentioned to Teddy Pardo, that I have acquired and in use
Of Eversolo A8, Nutul, please bear along with me for a moment, Throughout our ongoing conversation, he had asked me if I could hold
On for just a moment, I replied yes absolutely, When he returned back on the phone and we had restarted our conversation he had made me
An offer that perhaps the average person of an A8 would not have refused, he went on to State lot if I sent my Eversolo A8 UNIT to him
I intern would receive a Full total deluxe outboard, power supply Absolutely and totally free of charge he would incur all shipping fees
To and from, And return the unit along with the original factory supplied stock, power supply..

At this Particcular point in time I was absolutely somewhat taken back, a very nice gesture I must admit, when I asked him more information about his
Wanting to offer such a nice gift, he had replied to myself that he had been wanting to build a outboard custom power supply for this unit for quite
Sometime but could seem to accommodate this unit for quite sometime, he when on to explain the situation, would I be Alright with an outboard
Supply box on top the unit or on another shelf and so on, went on to explain how much better the unit , MYBE, after this build, to make a long story
Short, I declined his offer , why ?

‘well number one greatest concern I immediately thought of potential problems, with shipping will I get it back in one pice, it just didn’t seem worth
While to my at this time, as I were receiving items here that looked like they had went almost completely through hell and back, it just seemed like
A problem to me potentially speaking, after also receiving a HATTOR audio pre, a bit banged up, but I worked with him in the past and I was
completely satisfied , his explanations to me naturally were all on the technical side naturally, in fact quite a few, yes this was tempting as hell
Anyway he had said to me if I decided for some reason to change my mind to please call him back, he did claim sonically speaking that the bottom
End of the music would most likely become somewhat better and in his opinion the unit would probably operate more smoothly and efficiently
Nice offer I would, say so.

‘keep in mind he also wanted to remind me that his modding the unit would most certainly void any warranty’s that were so implied by Eversolo
But in his opinion as a builder could improve the performance and overall experience of the sonics of the unit, I would believe that he has more
Than likely found his way through this as of this date, in short IDK, I’m half tempted to telephone him tomorrow and ask maybe, but letting my
Bit of so called secret knowledge out of the bag, if someone cared to participate I would absolutely tell you to consider contacting him as follows
Teddy Pardo/ 1844 297 6882 rest of the world, keep in mind I have great respect for him, but it is a business decision just like any other
But teddy p , had the otmost confidence that he could in fact make that unit perform and sound better, myself included I would most
Certainly have the best confidence in him at his word, note his web site at present still does not show or offer a power supply upgrade for the A8
So my point noted any pice of audio gear can be upgraded to a senseable degree, so if on person believes so let it be his own choice and opinion
Absolutely no need for anyone to get out of hand about it, none of us are absolute genius if so what are you doing here ? Idk

Sorry folks I must get or buy a new or decent
iPad or laptop , oh well ……

 

Power supply induced noise is only, ONLY in the form of background ripple noise.
If that noise stays well below audibility (at full scale, that is, about -115dB FS) you can be sure, dead-man-walking-sure, that there is no way that noise can be audible.
If you listen at -30dB (ordinarily high) that noise would lay at -145dB. Now I dare you tell me that you can hear it...
Bear in mind that I just scattred here some numbers that are common sense, and roughly equal among ordinarily professional PSUs. Not about some cheap wallmarts, despite the fact that there are some of those, that perform pretty well (but we cannot use them with the A<whatsoever>. as they are for 5V externals... Nevertheless, the tech is here, and is here to stay.
All these Teddy Pardo-like manufacturers... all lunch on the same principle: "audiophools just want vapourware, and we're just gonna give'em plenty of".
You can disprove me anytime; an I would like to... stakes are low, though.

Nevertheless, keep up chasing the unicorn. It's not getting one. It's the endless chase itself that is amazing.

 

Nutul thank you, I was just merely sharing a story, a true story with you., one reason only being is I have a great deal of respect
For teddy pardo, from doing business with him in the past, along with a few other folks I know as a very good and upstanding
Reputation, I am not insinuating or implying that you may not agree, but I did so STATE in which I do not think my wording
or explanatory sentence was put forth that remember, and the long run. This is a business like any other to me. The word would
Absolutely speak for itself., I am not saying that Mr. Pardo is only in it for the money, but I have seen him turn down work in the past
in which in his opinion was indeed not worth modifying repair replacing or added adding onto, so to myself if the man sees something
That perhaps maybe I don’t. It may be worth investigating., now again to myself believe it or not. It really wasn’t that important.
Again without getting lengthy. I was giving a two year parts and labor warranty by the distributor which I have in print the only shady
Part of the warranty states if parts are still available, that’s absolutely another story. If the unit is still being sold, I’d be most certain
That absolutely there would be parts available., I don’t know. Maybe I’m moving in the wrong time.. but I did believe it was someone interesting.
But thank you for your reply or post, oh well everyone’s dreading tomorrow Monday, please have a nice safe week ahead. Enjoy the music
And yes I do understand what you are saying and where you are coming from and so does the one gentleman here which is also in agreement with yourself
Thank you again.

 

I am not saying they sell vapourware only. Their products may well be of quality (read: tey most probably are); or, in other words, well thought, well engineered, and well manufactured.
This implies time, resources, time, quality components, time, testing, time. Oh, and let's not forget time.
Nevertheless, nowadays cheap (relatively, if well done) SMPSUs are at the same level of quality, when it comes to noise audibility / propagation.
This, and only this, was, and is, my point. And I stand to it.
To tell you a brief story:

I run my system through actives only: an active sub, which receives the L/R XLR outputs of my DAC (an Everolo Z8), applies its LF and HF filters, and replicates the audio signal to its XLR outputs towards my L/R active speakers.
Now. When I switch the sub ON, and I am in the whereabouts, and the house is silent (that is: no kids / wife around, no washing-machine / dish-washer / vacuum-cleaner / etc. etc. running) I indeed NOTICE a faint buzz - at 50Hz, as the sub (and the satellites) are class AB with internal, linear PSUs, and I am in the EU, so no other frequency should be thought of...
NOTE: not hum from the sub itself... not electrical hum. More like a component's vibration (the transformer's laminate pack? an inductance coil? cannot tell, although it sounds more likely to be the former...)

At a rough, ear guess, this might well be at something like -80 dB. And I can distinctly hear it only if I am closer than about 1m from its backplate.

My listening position is at about 2.5m from the satellites, which implies (the sub is in the middle, between L-R), roughly sqrt(2.5^2 + 1.25^2) => 2.2m away from it.
I (critically) listen, usually at -40 to -30 dBFS (my speakers are in the realm of 105dB sensitivity), so I am actually listening at an average of 70dBs.
The noise of the sub's PSU is now at (matematically speaking...) -150dB.
Human sensitivity is stated, and worldwide accepted to be at (average, again) -115dBs.
I no longer wonder why such hum from the sub is not an issue...

I can, of course, open the sub, and replace whatever it is its PSU, as now, almost three years after its purchase its warranty is over...
BUT.
But... what for, as it is completely inaudible for me (57 y.o.) at the listening position (let alone if I casually listen while walking around the house...)
Thing is: if it were 20 bucks, who cares, let's try.
Being in the 100s, and thus approaching comparable realm with the sub's price (about 700 EUR), I really find no interest, nor utility, in even thinking of doing so.

The real problem is... there is no need of bandaging the head before injury... if it doesn't affect your listening experience, there's no need to intervene.
In other words, to stick to an engineer's POV: "if it ain't broken, there ain't no need to fix it."

HTH
Cheers, Al.

 

Hello Nutul ,Thank you for your most. Interesting post, reply , I appreciate. I believe what folks.are absolutely trying to accomplish or looking
For, from what I can interpret and understand, I honestly believe this true, in regards to the aftermarket PSU units, It’s not so much about
Distortion or let’s say even basic operational performance, I honestly do believe this is where a great deal of confusion sets in,
Naturally, I will go on to stay why, Believe it or not, I think most folks could really give a hoot about specs , measurements to a certain degree, not that they’re not important
to myself this is what transpires and I absolutely believe this is what’s been happening, putting everything else aside for the moment
It’s honestly and truly about, Seriously, speaking getting better sound, one might say, what do you mean by better sound ?
let’s take it as you will, someone on my claim I have gotten much better base definition. The high-end seems more extended the mid range
Sounds more focused, and so no etc. …

that is where I honestly believe our cross reference lies, As I believe naturally, a dedicated engineer from an electrical standpoint, we’ll see
No real advantage in doing so, I am not an engineer, but I have been doing this long enough to be an absolute agreement with most of the guys here
But like I said, however, I think the biggest part that is being missed when Audio files were guys speak of PSU‘s and their replacements
Again, they’re more looking at overall sonic improvements only, I can certainly see a bit of let’s say misrepresentation on thought of
These aftermarket units no matter how well they’re made or who made them or where they’re from regardless, The biggest belief
And honest understanding of what is being looked for again, but implied in another way, our beneficial sonic changes
Now, if so, by someway, Let’s say be so-called sonic changes or differences, perhaps may not be in favor of everyone and even
If there were some type of improvement, it very well indeed may not be an improvement in your particular system.

But again, where I think conversation absolutely gets crossed referenced to the to the degree of or by way of the PSU itself being in question
From an electrical technical aspect, When the only real interest the audio head has, Is naturally hearing the aftermarket PSU to absolutely
Make a better man overall speaking as far as their streamer do digital audio system, All right, we can even say preamp for any other piece of equipment
Although what I am saying would be somewhat contrary in nature as to being specific on this particular topic of replacement PSU units as a
Definite upgrade to their unit or units in a general result, However, most of us know that better parts much better parts can always be
Or implement it, We have all seen capacitors perhaps sell for 2 or 4 dollars apiece, And we have seen the same capacitor identical in value
Sell for $.300 or 400 dollars apiece, just use as an example, As a matter of fact, let’s say putting in a audio note or milflex capacitor’s ect, totally different situation not in use of a psu build .

Will this sonically alter the difference?, Again, just being a novice, but being taught and shown by a few interesting people that would know
Like a few of the folks we have on this fourm, I may be somewhat of a believer, but absolutely not in the PSU unit, If it is indirect line
And connection somewhere along the signal path, Yes, I have heard minor differences in using different capacitors, In which were mainly intended used as
Bypass capacitors, Coming off a driver tube, pre driver tube .Then over to the 300 B output tube, Yes, some very minor changes in sound but they are there, yes this is off subject entirely different use and implementation of area control of unit

But in the ending of it, all I think with guys don’t understand, To a certain degree, just my opinion. I really could not see or believe
How how by way of upgrading the stock, parts factory parts and your power supply unit, Could possibly make any sonic difference
Less perhaps it was a total redesign of the original PSU unit, and even at that, I do not see where you would gain any sonic arbitraries
I believe this is the biggest problem that folks let’s say maybe don’t understand that you’re not give any thought or consideration of
I’m not brings off an immense amount of confusion, By way of PSU sonic upgrade, I would not condemn anyone, In lack of that, knowing
We were all taught we all had to learn, Not to be repetitious, but I do believe there is somewhat lack of communication in this particular area.

Nutul thanks, again for your very detailed and descriptive comments and replies,
Please have a nice week, enjoy the music even with the low level hum
Nice post / comments in response on topics …
106 db incredible I don’t believe or know of
Can’t get more efficient than that, unbelievable
I like that, I know some won’t agree I certainly
Do !

 

They are active studio monitors... such levels are almost in the ordinary. ;-)

 

Yes I certainly realize that kind of a wonderful thought in use as what I would assume it safe to say an active loudspeaker system ?
Just in general in comparison To my own, at 104 db According naturally to manufacture specifications,, In comparison
To your rate, efficiency and use of , I believe the top rated number I was ever aware of was at 108 db, this was a single
Audio speaker set up one per cabinet, DIY that is a time was offered by Ron Welborn, of the nail closed, but not forgotten
Wellborn Labs, And set up of concentrated on SET AMPS, and Lowther Full range or speakers at that time years back
At present I am not absolutely would transpired or changed, but as of now I believe 102, however, approaching
Perhaps 95 one up, Perhaps a bit lower would get the job done for me. Yes, the higher efficiency absolutely has it advantages
And also some disadvantages. I would imagine everything is a trade-off at some point along the way.

please not to go back in to this discussion again I do think it’s somewhat safe to say with the Eversolo units in general
The folks with the higher sensitivity rated loudspeakers sometimes were at wonder why folks were complaining about low level
Volume or gain output, to myself in my own belief when you were dealing with such high sensitivity there’s really not much
to complain or fine fault with with the overall output of almost anything. I have been running a 3 1/2 Watt EL-84 set tube amp
Direct at most times. It’s very difficult to even come near 50 or 60% of its total output , far from perfect as the system sometimes
Suffers, sonically, and other areas, especially way down the bottom. in, which is only somewhat natural or normal for a system
Has such. The issue at hand is easy enough to address but it’s going to cost you a bit, but the condition is very curable

Nutul please excuse me, I would assume your speakers are 2 way ?
If you would , just inquisitive . TY …

 

They are indeed.
For this I have the sub.
All class AB, for instance...

 

Nutul, sounds like you have quite an audio system, Thank you I appreciate it.
I like the class AB, im trying to get in
In touch with some of the newer offerings
Idk, But I still prefer let’s say that somewhat
Older methods in use of

 

Just ordered a LAiV Harmony uDAC and a Fiio PL50 external linear power supply

 

Good man you are supporting the Hi-Fi industry.
