I didn’t waste my money on a Dave to shortchange it playing inferior files. If every part of the chain matters, then let’s start with the files themselves.
I just have a hard time understanding putting so much into what comes after that files that you wouldn’t care about the quality of the files themselves. Would think all the other tweaks would make it more noticeable. And changing to better files is actually cheaper in several countries if you choose Qobuz over Tidal, so seems easy choice.
It's simple: the better your gear gets the less the file format matters. The quality of the recording is what I hear. I can no longer blindly tell if I'm listening to 16/44.1, 192/24, DSD, or MQA.
I wouldn't spend all my money on this gear and then limit the music I listen to because the wrong kind of filter was used. The music is what's most important.
I have played Joni Mitchell's "Blue" in MQA format for friends. The reaction I hear often is something like "wow I've never heard this album sound so good". I have an earlier mastering ripped from CD that doesn't sound as good. Why? Not sure but it very well could be that the master from which the MQA version was cut came from a better analog tape or it was converted to digital with a superior A/D. The recordings provenance is what matters most - not the file format.
I hate to be so blunt, but you really have no idea what you're talking about when it comes to the importance of the file format. I used to be a vinyl guy so it isn't the first time a person has wondered how I could listen to an inferior format.
It seems to me that the prestige of owning one of the finest DACs, the DAVE, matters greatly to you - and that is why you won't "shortchange it playing inferior files". I want a DAVE for exactly the opposite reason: because it will make more enjoyable my entire music library. It will bring forth richer tone, more accurate timbre, better timing, and more naturalness from even the worst recordings. Before I owned this Chord gear, I often found myself having to skip past too many recordings because they had a tendency to be too harsh. That rarely happens now. Better gear makes everything sound better and enables one to get far more enjoyment from listening.
The irony in all this is that the Rob's DACs can make MQA sound spectacular. I don't think I'd be this positive had I owned a different brand of DAC.
