Yes and via Squeezbox, you cant tell which duplicated albums is the MQA one because there is no indication via that interface. I promised myself to never play a MQA file through my system.

The most useful advice for you was to try listening more. Look at the numbers is all you know how to do.
You quoted me above but you actually edited the quote. A sin, whatever the reason.

That you put it in a location where it does not matter, in other words, overspecced the part.

Use it for AVCC in a ESS DAC, or the comparable voltage reference pin on an AKM DAC, or any other location with poor power supply immunity, and your statement is patently untrue.

It was at least in part a question. Is there a player that reads the file from disk entirely before starting playback? It's something I can imagine an extremely paranoid person would do. I thought I've heard of some player that did this, but I don't want to misstate the facts.

I did not insult any makers of digital audio players, except those that are idiots. I do not know of any examples that allocate a buffer for the entire file. If any player reads the entire file into memory for playback purposes only, the author(s) deserve my scorn.

Well, it's not even a big sin these days with the amount of RAM available on a PC... but it is arguably bad practice anyway aside from the asinine reasoning that the storage device will not have to be accessed during playback.

Dan, when you hear a difference between 2 bit perfect copies of the same file, then one explanation would be that you have supernatural hearing, unmeasurable and unprovable to the norms. A waste of time and effort to pursue here.

I'll bite on this. I am 100% sure there is a measurable difference if you use a 7805 for VREF / AVCC, but how sure are you it's audible?

It might be, but I would not bet my life on it. The Rohm 7805 that AKM uses has a noise spec of 40 uV RMS from 10 Hz - 100 kHz. Not state-of-the-art, but appears to be lower than TI's LM317 if I read the datasheets correctly. PSRR is a bit higher in the audio band, too. Not amazing compared to new regulators, but I bet I could feed that to the VREF of an AK4499 and normal humans would fail to identify it in a blind test.

Agreed. Maybe he has X-Men mutant power of hearing.

Perhaps you are correct, I haven't followed the matter closely for far too long. However digital playback are not only PC based, it is going into smaller or embedded platforms like the Raspberry Pi with multi channel filtering, equalization and crossover function.

There you go - see attachment.
A file player (Amarra) by the same company that created mastering software that up until recently was used in production of about 90% of all digital releases on the market (CD and High Res) since 1989. Player uses the same playback "engine" as the mastering software. Modified (encrypted) version of this player is produced on the fly by the mastering software and is sent to client for playback of final DDP file to get their approval.
Now go and call Sonicstudio and tell them that you know better.
Ignorance is indeed a bliss.
