Can you hear bit rate?


Almost all the music I listen to these days is from Roon and often a "station" created from an artist I like.  So I click on say Melody Gardot and Roon start randomly picking similar jazz music.  All great.

As Roon finds new tracks I get stuff rom Qobuz or Tidal and in a variety of bit rates.  from 44.1/16 to I think 96kHz/24.  Sometimes I think "wow that sounds great" and the source material is high res, other times it is not.  

I've typed here for a while that around the turn of the century DAC's have gotten much better at paying Redbook (44.1/16) music than before, so that the difference in sound quality is almost gone.  In addition I use Roon to upsample everything to 176 or 192 kHz.  

I'm finding the question of source depth, at least with PCM, kind of irrelevant these days.   What do you think?

All the 24-bit recordings I’ve heard have a liquidity, flow, ease, and naturalness about them most 16-bit recordings don’t, and as a result they sound relatively, for lack of a better word, grainy and less refined/natural by comparison.  But there are 16-bit recordings from the likes of ECM, MA Recordings, etc. that do possess that liquidity and sound very much like 24-bit recordings, so I’ve found it can be very recording dependent.  Either my DAC/system is good enough to clearly hear those differences or my DAC isn’t good enough to allow more 16-bit recordings to sound better (or just doesn’t gloss over their shortcomings, but that’s a whole other can of worms) — dunno but that’s my experience.

So this is a philosophical thing.  When we can hear a difference between 16 and 24 bits, is it really a good DAC or a bad DAC? 

In other words, is it that the DAC is inadequate with 16 bit recordings?  Would a better DAC play 16 bit recordings as well as 24? 

It's more than just resolution. I've heard 16 / 44 sound great and there's 24/192 that can sound worse. It seems that how the original was recorded and mastered is FAR more important than the broadcast resolution. 

BTW... Be careful up-sampling in Roon or Audirvana. Pushing the envelope can many times make things worse.
