I have A10 not A8. The Eversolo DMP-A10 does not have a specific "upscale music" setting or feature in the traditional sense (like A6). However, its high-quality components and design contribute to an enhanced listening experience that can be described as upscaling by improving the overall audio quality. I’m curious about A8！
TBH, all delta-sigma DACs DO internally updample to insane frequencies. This of course is not visible to you as - for example - upsampled to 192 kHz (and redithered to 24 bis, for instance...), but the result is the same. Your original 44.1 will be internally up-sampled to 768 kHz, as would your original 192 kHz one... no difference for you (well, your ears...) so, why actually bother if the actual "source" of the DAC is the at the same sampling rate...?
Nutul very well put, gentlemen, and let’s just say for lack a better terminology, The audio guys, That have been putting music on computers, Since the late 1980s very early 90s As we travel through time and numbers keeping increasing and appear to keep climbing higher , although in reality, the numbers do exist, there are somewhat useless when you consider the source, throughout my observation and learning through Computer or Audio guys that really know I’ve been trying to tell me this for countless years, without further detail or explanation to myself Due to learning from them and some experience along the way you are absolutely 100% correct, in other words to assert extent Why would you even bother of course, depending upon each individuals own beliefs And personal opinion, but it always made perfect sense to myself from listening to explanation and learning sonically speaking, you may alter the overall signature, But you cannot create something they never existed in first place Thank you, excellent explanation excellent post
That is my actual point. Upsampling by yourself may "only" ease the work of the DAC, that would have to updample from 192 instead of 44.1... but still, at hardware level, this is irrelevant.
;-) - it took A couple of these gentlemen, Thank goodness for patience, Quite a while with many types of technical and explicit explanation Before I finally comprehend it and perceived Innocence as to what they were explaining To myself, I apologize in advance. I do not want to offend anyone. This does not apply in every area, but their biggest saying our statement to myself was always as follows, all hype. Take it with a grain of salt, I finally seen The light !
As far as I'm aware none of the Eversolo streamers A6 - A10 has an upscale function(For example, I understand that this would take a 16-44 audio file up to 32-768 on playback). They can play back audio at any sample rate up to 768pcm or 512dsd. So you input say a 16-44 CD will show up as just this. I do upsample from my Audio PC program to 32-768pcm from say 16-44 file and this shows up as this on the screen. I've experimented with DSD and this is the same a file input at 512 shows up as this. Subjectively upsampling is an improvement in sound but lets not tear ourselves apart over this.
The A6 can upsample to a range of user specified sampling rates, max 192 kHz, provided EOS setting is turned off. I generally upsample CD rips x4 to 176.4 kHz because they sound better that way using an external DAC. The DAC is a Holo Audio Cyan2 which is a pure NOS R2R type, hence upsampling the input to that device can help. If I was to use the internal A6 DAC, it would intrinsically upsample anyway.
In your case the DAC won't internally do ANY upsampling (NOS == Non-Over-Sampling) so that manually doing it will take over the work thqt any other DAC would do internally... Despite the fact that oversampling has little to no effect on our (human, not mine or yours...) ears, it can indeed ease the DAC's work for what is noise-related< although this kind of noise is, still, well beyond human perception. We're haunting witches here...
NOS style DACs have a well known rolloff in the very high audible frequencies, this effect can be pushed further out by upsampling their input. The plus factors in terms of soundstage etc are what make me pick an R2R device over the DeltaSigma chip styles. Of course if you are a user of say HQPlayer upsampling software, then you absolutely want a NOS device, you don't want to upsample again. Users who go that route will claim that upsampling does indeed matter and exactly how you do it can also affect the sound. I think it is usefull for the A6 to have this upsampling so that users can have options if they are using it as just a streaming transport.
As I said. all DS DACs already upsample to insane levels, so... what difference does it make, to you, upsampling to e lesser degree, BEFORE the DAC itself would to a higher one, nevertheless... It makes no difference if you do it, or the DAC does it; may you agree? For NOS DACs, of course, the realm is different; but we're talking of DS ones, ain't we?
I explained that upsampling for me on the A6 is usefull because I use a specific external DAC which is not DS. There may be also others who prefer that type of system and the different sound it can generate.
How have you connected A6/A10 to NOS Dac? The latest software update for streamers has an update that allows the choice of 48,96 and 192 on the coax/optical output only(this is limited to 192 max for these outputs). To get the best from a NOS dac you need/should feed it up to 32/768 which the Eversolo streamers can't do. You don't need a NOS dac the Eversolo Dacs can take 32/768 via USB input from another source(PC or other). This is what I do. I use Xxhighend upsampling software in a dedicated PC-USB A8 input. Your Holo Cyan is wasted really unless you get a dedicated upsample source even then you could then run this into the Eversolo and not use the Holo. I've not heard the Holo myself but the A8 certainly sounds excellent and you have the A10!!!
Firstly I have an A6 Gen1, never said I have an A10. The max sampling rate setting in the latest firmware you refer to is to limit (or not) the digital output via SPDIF. Instead I use the USB output to connect my Cyan2 to the A6, a more flexible solution as regards sampling rates. The Cyan2 DAC is of course not wasted, it sounds to my ears very good at any sampling rate even 44.1 kHz. If the A6 permitted it, I would use higher rates. I hope the forthcoming T8 streamer may offer increased upsampling options. I also use a Shanling ET3 CD transport as a different source for the Cyan2, that offers upsampling to 768 kHz or even DSD512 from either CDs or local files, then fed over I2S. So I have tried higher upsampling into the Cyan2, and I prefer PCM at high rates compared to DSD. But the sonic difference to the more lowly 176.4 kHz that I use from the A6 is not very large and I am content. Using more tuned upsampling solutions as you appear to do may generate better outcomes I have no doubt.
So upsampling out the spdif is possible on the a6 but that function does not exist on the a8? I have the max sample rate output set to 96khz on the spdif output menu, but the signal stays at 44.1.
Hi Mjay71, yes upon viewing your post I believe perhaps you may want to check your external digital audio converter/ DAC. I have an old MYTEK DAC, I keep Sitting on top of my A8, I have found that what ever Rate the the A8 is outputting, the old MYTEK displays the exact output as the Eversolo A8, on both SPDIF Or USB. I keep the old MYTEK just as a comparator it was quite a good dac in its day I still enjoy it. It’s an ESS Saber 9016. by the way, I thought it was somewhat outdated until I came across a very high-end manufacture using the exact same implementation the 9016. just a bit of information I thought you might find interesting now we’re talking 12 or 14 years later. I apologize this is not solving your problem. I would go back and check everything especially your settings on your external dac along with are you using the proper Dig cable not that I ever found this to be a problem in any set up, now the oppo output I could not collaborate as I never use I believe one time trying to hook up a buddy’s TV, believe it or not this was the only digital output the unit actually had I would go back and just check everything out give it to once over but absolutely I have found this to be pretty likable. Whatever the Eversolo A8 is outputting it always displays right on the front of the old MYTEK Hope this helps you but to myself it would only make somewhat common sense but not in its entirety just because one unit performs a specific output absolutely doesn’t mean another model is going to, but I can guarantee whatever that A8 is putting out your dac is seeing that exact same signal if you would like I could find a way to send you a screenshot really not into that sort of thing, but I got a friend of mine. He is very capable. I’m certain you’ll figure it out. recheck all your settings, Have a nice week, enjoy the Music
I think that is correct but I don't have an A8 to check. On the A6 you turn EOS OFF, and there is a separate setting to choose the sampling rate you want. On the T8 no upsampling option.
I don’t know guys,my EOS is always ON, But I do see your point, however again it can be a little difficult at times with problems as such to sort our problems and perhaps give a correct diagnosis Unless you’re actually standing right in front of your equipment, you are trying to work on or rectify other problems, years of experience absolutely does not make me any type of an expert But it does sound to me. I don’t believe the error is coming from the Eversolo A8. I believe his particular Problem is lying somewhere within the settings for adjustments of his external Dac, I could be most Certainly wrong. a good week to everyone enjoy the music, relax
on the a8 under spdif out there is a max sample rate output, but it doesn't seem to have a function as far as I can tell. With EOS off, streamer plays and sends 44.1 regardless of where I have the settings. With EOS ON, if I have the spdif out max rate set to 96khz and the player streams a hi-res song at 192, it outputs 192khz. Out of curiosity, what is the purpose of that function if it neither upsamples to the max rate nor limits the sampling rate output to the setting?
My DAC does not display the incoming sampling rate, and has a chip that is limited to 96khz max. Everything works and sound great with EOS on until a song comes on that was sampled higher than 96khz and then it's crackly. That is the limit of the DAC, of course, so I was hoping there was a way to limit the sampling rate output via spdif. I'm confused what the spdif "Max sample rate output" setting/function actually does.
