A02 has only line out, but no HP output - or I am wrong? How did you adjust volume?no external amplifier needed with A8000 iems and n6ii

Maybe @ExpatinJapan meant the E02 module. It can be a bit of a memory challenge with all these model numbers and names.A02 has only line out, but no HP output - or I am wrong? How did you adjust volume?

Is anyone running TIDAL with their N6ii for MQA? I've been trying to help someone else out on a DAC issue and I used my N6ii as an MQA reference. When playing some some TIDAL Masters songs, my N6ii shows sample rates like this:
So, in that example it is showing 384kHz as the sample rate (top of screen).
It emerges that this might not be correct. The suggestion is that the N6ii is oversampling the correct MQA unfolded rate (which should be 192kHz for the song shown on the screen in my picture).
Is anyone able to verify what you are seeing when you play a Masters track. I only ever see 352.8kHz for a TIDAL Masters 44.1kHz song, and 384kHz for a TIDAL Masters 48kHz song.
Apparently, some TIDAL Masters are 192kHz when unfolded.
So, the question is this: is the N6ii oversampling TIDAL Masters songs? I tried playing Masters songs in UAPP too and I see the same rates at the top of the screen. If it is oversampling, then is there a way to deliver the true MQA sample rate?
A quote from another Internet forum.
"Tidal confirmed that the Windows Tidal software will do 1 x unfolding and offer up to 96kHz to your computer's internal DAC or to external non-MQA DACs. External MQA DACs can do 4 x unfolding for the maximum sampling rate (384kHz)".
The N6ii would appear to be doing 4x decoding/unfolding which is very good.
UAPP can only display a guess when its playing MQA as there is no way for the app to get the true unfolded sample rate from the hardware.If you follow from there, it looks like things with the N6ii are not quite right. The person I was trying to help has an MQA D90 DAC and it's showing 192kHz for that song. My LG V30+ phone is showing 192kHz. And someone on that thread confirmed that Coldplay Masters songs unfold to 192kHz only.
I think the difference comes from the fact that the Topping D90 is a full decoder, so better? Maybe? and the N6ii is a renderer.@MarkParity Okay, so that rules out UAPP as a reliable source of the sample rate. Thanks for that info. Then I suppose there's the MQA D90 DAC that I posted the discussion link. That's showing 192kHz on its display. One of these must be wrong! Either the MQA D90 or the N6ii.
The way MQA is advertised and explained is not even close to what I would expect to be transparent and understandable stuff. Then yes, they need to keep it proprietary. It reminds me a lot of the historic HDCD stuff who wanted to conquer a portion of the Redbook CD financial cake by adding proprietary hardware and licensing. (Anyway, at least they [Pacific Microsonics] gave the audio world the best sounding analog-to-digital converter which stood the test of time long after they folded.)Its all here, but not necessary self explanatory.

Thanks, @Taz777. I‘m absolutely the same type of person. And I would hope for an official clarification, too. (Guess that won‘t com from the MQA inventor / owners...) The questions have been asked - upsample after MQA unfolding, what is MQA rendering, and what‘s the ”true“ frequency contents of an audio file.@111MilesToGo Thank you for your post. So there is a possibility of an issue with 'pure' MQA decoding on the N6ii. I'm a 'bit-perfect' kind of person and don't really want any upsampling of any kind. I don't ever use EQ either. I just want to hear the original unfolded Masters track. I guess some official clarification on this point should be made. Does the N6ii upsample all Masters tracks? Nevertheless, I'm still loving the N6ii. It's just a concern in the back of my mind.

Well, my 2 cents on MQA, FWIW.
First, the observation on my N6ii with the original Tidal app is the same, every MQA track ends up unfolded to 352.8 or 384 kHz, depending on whether it is a folded 44.1 or 48 kHz.
Second, I did a bit of playing around on Windows with Tidal via their own app and integrated within Roon, using the N6ii as an MQA capable USB-DAC and my Chord Hugo 2 as an MQA-incapable (should I better say averse?) USB-DAC. Unfortunately, I couldn‘t get to conclusive results yet regarding how to properly do the settings for the DACs, either in Tidal or in Roon.
Third, my thoughts on MQA are more on the reluctant side than on the enthusiastic.
For example, look at ECM Records, a fully respectable label (although having joined Universal for distribution) who decided to jump the hi-res bandwagon after quite some waiting, and went into releasing MQA versions even later. I was just wondering why on earth their MQAs do all unfold to 384 kHz, independent of whether the hi-res PCM releases are 96 or 192 kHz. So if there were some "true“ audio contents up to 384/2 kHz, that would mean that they must necessarily have done a new remastering from the original analog tapes. The easier and more probable way to produce an MQA file would be to take the pre-existing hi-res PCM and subject it to the - lossy! - MQA encoding.
From that observation - as you said before - it might be possible that the N6ii would upsample after unfolding the MQA. On the other hand, what does "MQA renderer" mean?
So the underlying question is: What is the "true" original sample rate of an MQA track??? I.e., up to what frequency does its real audio content extend??? What one would like to do is: We - at least some of us users and some hi-res download stores - have been analyzing the frequency distributions of PCM tracks using software like Spek or Music Scope. This does quickly distinguish true hi-res PCM masters from upsampled fakes being sold. So one would really like to look at the frequency spectrum of unfolded MQAs.
Another example: During my - admittedly still short - journey with MQA, I came across quite some MQA releases on Tidal that unfold to 300+ kHz on the N6ii; however, no hi-res release at all does exist anywhere, just CD quality on Qobuz / Tidal / download stores. I think that‘s a bit astonishing, but not impossible. I found quite a number of such releases on Rhino / Atlantic.
Finally, I agree with
The way MQA is advertised and explained is not even close to what I would expect to be transparent and understandable stuff. Then yes, they need to keep it proprietary.

Notwithstanding the last paragraph, I do enjoy to have so many choices nowadays, and of course to have the N6ii. Just got my E02 module, unfortunately still fighting to get a balanced IEM cable ...
