Change power supply DMP-A6 GEN 2 with LHY AUDIO LPS-A6-MKII ?

I certainly agree with you, but not with your philosophies but keep them over there with you. And your other band of unwavering followers, but It’s all good

 

Okay, I'm officially confused. Which power supply are you referring to that has an 80% failure rate? Is there some post in the thread I've missed?

 

The same PSU’s or power supplies that a few folks rolled over to a buddies works back workbench. I believe they’re called the A6’s in model , Al you know I would never debate
you’re extremely professional knowledge, I am merely reading statistical facts I am in no way being condescending towards yourself as I have great admiration and respect for yourself as I’m certain you’re aware, but if you would like I always back up what I can say I will gladly send you over some statistical analysis reports of complaints. Please let me know not a problem. it’s a bit early here in this part of the world. Please let me gather some together. I will gladly forward them along with other claims and comments absolutely for you no problems whatsoever

as always, I remain respectful yours thank you for asking,
I will certainly absolutely check back in just a bit as I must fulfill
A few standing obligations as of this present time Thank you for understanding…
Before I proceed, please excuse me, but it seems every time one of these gentlemen do not
Receive a favorable or within an approval response it certainly seems it appears to myself
They come crying to you in hysterics until you throw them a life preserver
Absolutely no pun intended. Just curious with all due respect as it certainly
appears that way again just wondering. Like school girls ,
I believe you see my point and view. Thanks Again ✔️

 

@Biamp300B which DMP-A6 models are you referring to? Gen1 or Gen2? I haven't read on this forum about any Gen1 PSU failures that I can readily recall, although I'm reasonably confident there probably has been some over the past few years based on typical MTBF data of domestic equipment based on statistical probability. However, the failures of the DMP-A6 Gen2 PSUs are well documented on this and other sites. For context it would be advantageous to clarify which PSUs you are referring to with the 80% failure rate.

 

Hello biamp, but who are you talking to?

 

‘Hey hello Ghislain , please correct me if I’m mistaken or incorrect, but I believe to the very best of my knowledge, I was in reply to,
Mr.AL Rutlidge , however sorry for any confusion, I’m certainly unaware, idk, please advise if care to explain, if not . No worries

Please have a wonderful day,

 

Hi Al , I certainly understand your concern in regards to PSU failure, not to evade your question, the power supply failure is power supply failure, just speaking for myself. It doesn’t matter what unit in particular they failed in they failed. now I am starting to observe users of the DMPA8 having similar problems, example myself included, but again, however, on a very extremely small scale, in comparison to the A6’s. I would assume most likely there are a vast amount of folks that purchased the A6 over the A8 , in total count of these particular model numbers, perhaps double in overall amount again in comparison to the A8, perhaps more , however we both coincide and agree that there’s certainly our numerous problems And most likely will continue to have such throughout the foreseeable future in my personal opinion or at least from my current knowledge and observations, our one audio group buddy has a early model generation one, he’s fortunate he absolutely does have some workbench or test knowledge. I remember a small blue in color capacitor had just popped in sound , one night, this located on the power supply board or PSU he was lucky enough to have a substitute or temporary replacement in his personal shop,

* Funny approximately 10/15 minutes past I just talked to a guy that put the big PSU in the 3 transformer unit that I had showed you a picture of and I had decided on not installing, I believe you may remember correctly or it’s probably active or posted here after my very nice conversation with yourself. I decided just to leave the stock PSU within the A8, for specific reasons that we discussed, getting back on track, he’s also an old head what we call, 50 years + , he went on to state he hear a Tremendous amount of
Difference, he when on to state everything just opened up, the Bass became si pronounced he had to take it down a notch or two, I don’t belive the guy, I have absolutely no reason to believe the guys incompetent or just , BS,ing me,, it seems as broad as it is long , seriously idk. Maybe you tell me. I’m just curious as the next guy , you’re the expert but if you can swap it out , do it. Although as I’m a believer as yourself, Don’t fix something if it’s not Broke, how many times have we measured various devices or any other device only to find out differently ,now theirs a chance his A8 will blow up in a week, oh knows, I hope not . if want to view some or all the information I found, on PSU failures, I will happily Accommodate your request, I also came across a good deal of former usrers , that headed in other directions , it’s not hard to find I’m certain your aware, Shame all this wasted Time and effort over some self appointed electronic Genius, oh well … thank you AL… however I believe I had my limit for now gets a bit redundant , repetitious and ridiculous, SORRY lost part Of reply idk why, However this appears to be good , end here , I’m most certain, for all , sorry for the very short post, I didn’t have the time for a longer one

Al PLease have a good day and a wonderful weekend , hopefully


*
However some will NEVER AGREE, but I Seriously don’t believe all these folks are just hearing things
I’m certainly not saying or recommending that you do so, but I absolutely cannot agree.
All these folks are wrong. Or hearing things , let’s be somewhat reasonable… however, in my humble opinion,
and within my own personal use for myself speaking it most likely would not be worth it in my particular situation,

 

80%? How the heck would anyone know that (other than Eversolo maybe)

 

Precisely I didn’t say where I got it from a just around an approximate basis , well, here’s another hint it appeared. You haven’t gave it much thought when the service department set up a dedicated request line for PSU units that took a crap, I was never a CEO or a board member but the percentage ratio must be pretty damn high, maybe it’s 60% maybe it’s 90% that approximately what I was given is there anything else I may be able to help you with no problems just ask, If you don’t ask, you’ll never know. Ask questions that’s right that’s how you learn, any electronic audio device can fail at any time made by any manufacturer. Any model or at any cost without giving notice it happens And every once in a while, it does happen in a very high percentage ratio,

Look at the tens of thousands of vehicles that were recalled do we have a solid number probably not but it’s a good approximation and very fair and acceptable answer to my question Approx 80% and still counting, now it appears the A8”s are popping up in took a little longer to happen, Plus all the unreported cases like my buddies original A6 that he rectified on his own, with a simple common capacitor being an ex bench technician since the 1970s retired,



you have a great weekend. Enjoy

 

Yeah, sorry but those statistics are anecdotal. There's no way to know unless you're the manufacturer. I don't think we should be posting "failure rates" here for fear of sparking unnecessary concern to buyers. I think all we can post with any certainty is that there was a batch of Gen 2's built within a certain period, that had a bad PSU.

 

From my perspective the discussion on this thread was IMHO getting a bit convoluted in so much as it started out with the OP asking if it was worth swapping the factory fitted PSU in his DMP-A6 ME Gen2 for a third party PSU but somehow anther product (the DMP-A8) got dragged to it.

As far as I'm aware, the DMP-A6 Gen2 PSU is a LPSU which powers both the digital and analogue circuitry, unlike the original Gen1 units which are purely SMPS.
The DMP-A6 Gen2 PSUs are auto-voltage detecting types, which from evidence presented in these forum pages did experience a number of failures which eversolo said were attributable to a particular production run in early 2025.

To reduce confusion I will comment that in post #27 by @Biamp300B his discussion appears to refer to third party PSUs for the DMP-A8 which is a different product to the OP's DMP-A6 ME Gen2; hence the confusion on the part of myself (and possibly others) until that post #27 appeared yesterday. Up until that post I honestly thought he was discussing the DMP-A6 Gen2 PSU.

Now for a bit of clarity for those playing along at home. The stock PSU fitted to the DMP-A8 is a dual PSU. It has a LPSU for the analogue circuitry; and a SMPS for the rest of the circuitry according to the information published by eversolo. It is also auto-voltage detecting so it will detect the incoming mains supply voltage and switch the primary winding taps on the transformer for the LPSU part for 110/120 or 220/240v as appropriate. The SMPS part does not have to use this feature as it will comfortably "adjust" to the incoming mains supply voltage automatically as do the vast majority of SMPS units. https://www.eversolo.com/Product/index/model/DMP-A8/target/uXoirEESmeVKKmVViAFMcQ==.html

 

You're right, majority of the posts definitely hijacked the OP's question.

We're back on track now with your post should anyone want to continue the OP's question.

 

What are you thinking about? Absolutely, they were certainly without no certainty. They wouldn’t have posted it in the first place oh mann not another one

 

I wasn't going to reveal this information at this point in time, but a very kind member of this forum has just generously donated and posted me his failed PSU from his DMP-A6 Gen2 unit. When it arrives, I will reverse engineer it to work out what the design is and then attempt to rectify the fault. If it has a fundamental design flaw then it might be possible to modify it to resolve the issue, depending on what the issue is. If it's just a poor choice of or a defective component(s) that has caused the failure then this will probably be a simple fix. But of course I won't know until I actually have it in my hands to examine it.

 

shame AL seriously I didn’t know I could’ve sent you 2 screenshots if you want them just have to go out in the garage. I absolutely had no idea. You were seeking one, but hold on just a second with the shipping for mid Atlantic US to where you are hell I don’t know if it would’ve been worth it, I never checked an actual weight. Can’t be no more than maybe a pound. Perhaps a little more well. Best of luck with that I believe there’s one working in one not, but like a buddy said if I can quote his words correctly, even if we back shoot it to find out what problem lies what’s really gonna become of it, so back on the shelf it went , oh well

Yes you are quite correct where all the confusion lies is in Chris Crossing on my part as my original post to you sometime back ago Specifically was in the replacement of the A8 with the 3 linear transformer unit that I had sent you a screen shot of which we had discussed thoroughly
In which I was in agreement with yourself Do not fix if not broke as I have a brand new one sitting here that was never used that I had received an a partial trade
In which confusion interrupt it the use of power supplies don’t make a difference if you remember correctly In which I really don’t care speaking on this again I am in agreement with yourself but I’m not even stipulating for the better ment of Myself, but within some folks have noticed some positive differences that is partly how this all got tied in a giant knot, i’ll just leave it right there before I regret saying something I don’t wanna say Even if it makes a little or no difference to myself, that’s not the point however I am an absolute agreement with you, never again not here

that’s very accommodating of you. Thank you. Please advise with your findings with all due respect,

have a great weekend

 

This is interesting because when I picked up my unit earlier today I spoke briefly to the tech who has replaced 1/2 dozen and I mentioned jokingly that hopefully I won't be back for another PSU replacement. He said something about a part that was different from the original and that because of this revised part, it would be extremely unlikely it would happen again.

Never occured to me to ask what the part was. So my guess will be that you'll discover it's just a poor choice of components.

 

Bloody hell!! Again, what's wrong with you lot? Your behaviour continues to be appalling.

@Biamp300B , although I don't usually understand a bloody word you say, in this case I expect a lot better from you.

@Purité Audio , once again, show some respect with your replies - I tend to agree with a lot of what you say but your simplistic, blunt and disrespectful way of saying it continually betrays your utter contempt for your fellow forum users and that is NOT acceptable - I can't believe you don't understand how much damage you're doing to your brand by acting like this.

Thank you Alan - a voice of reason.


@Zidoo Support-Kim , thank you for pointing me here with your concerns - if you feel we need to take further action we can pick up on PM.

Have a nice weekend everyone.

 

@Markswift2003

Thank you for your input, because I don't understand how my simple question led to this kind of discussion with these other participants.

I simply wanted to get the opinion of people who have replaced their A6 power supply with one of the models that claim to improve the A6's sound quality.

Reading this kind of behavior makes me less inclined to participate in the forum.

How did it start,? I believe that seems quite obvious however I will try to very quickly sum it up, it seems To always appear from a certain person that honestly believes he Possess much greater knowledge on this particular subject and numerous others, over the credentials of a gentleman that received 5 or 6 best international engineering awards in electronics and in audio engineering design, including power supplies, and power supply distribution importance , however I would assume that Mr J.Flutterman , ordered these most prestigious awards from an internet site that deals in these types of counterfeits because he just wanted to feel important within the electronics industry , Idk , i’m more than confident you can take it from here, just ask
Keith I most certain he absolutely knows the answers
To all your technical issues,

have a good day it takes All kinds, enjoy

 

Unfortunately it seems to be the way with audio related forums the world over.

But please don't be put off - most users, whilst happy to render an opinion, are also respectful of the opinions of others.

And of course you can always use the "Ignore" function if you feel the need (on the right hand side of a user's Profile Page).
