Ok, so I will take that as a yes, DAC’s do matter. Well here’s the problem:
EVERY SINGLE digital recording MUST go through an Analog to Digital conversion process. So when you click play on that track on Tidal or Qobuz, you are at the mercy of whatever piece of crap A2D converter was used at that time. Think about A2D converters in the 80’s, 90’s, etc.
A few summers ago, we toured recording studios. Their A2D converters are absolute junk. They said “$500 would be a huge expense on an A2D.” Many smaller studios are using the A2D built into their Mac computers and software.
They are not using high quality A2D converters like the ones from Merging Technologies. They are using very inexpensive A2D converters and up until about 2015, most were not even the equivalent of a Chord Mojo on the DAC side. I saw them with my own eyes and talked to a famous Mastering Engineer for confirmation.
When you add to that the obsession with compression, you now have a true double edged sword for many modern digital recordings.
Mastering Engineer Bob Katz is a friend of mine. I was introduced to Bob many years ago by our mutual friend Mike Chaffee who sadly passed away earlier this year from Covid. Bob has been to my house, I’ve been to his house, we’ve chatted many times. I’ve read his books on Mastering. I attended the seminar he gave to our audiophile society. Did you know that MOST recordings today are cut to 24/96, and those 24/192 files are usually just upsampled 24/96 done on not the best equipment in the world? That’s why the 24/96 often sounds better! I’ve talked to Bob at length to really understand what the hell is going on with digital today.
Here’s a little story: I have a local customer named Bill. His absolute favorite album in the world is “Sinatra and Strings”. Bill is a streaming/digital only guy. Every time Bill would come in the store, he would play the album and mumble wondering how Frank could allow such a terrible recording. “Listen! Listen!” he would say, “those strings are so harsh sounding. How could Frank approve of this?” I said “Bill, I have an original first pressing of this album at home and a MOFI repressing from the master tapes. I’ll bring them in.”
The next time Bill was in the store, I put on both albums, his jaw hit the floor. “It wasn’t the recording at all!!!!!” he shouted. Yup, it was the horrible A2D conversion process.
There are great digital recordings where they’ve taken the time and care to do things right. Listening to the recordings of say Rumer are a perfect example of outstanding digital.
But when you look at the Doors album above, that’s coming from the master tapes, using proper equipment and it will NEVER EVER see an A2D process, at least for the vinyl pressing.
So yes, quality matters, provenance of the recording version you are listening to really matters. Everything matters. And this is why audiophiles seeking the best of their favorite albums do their homework and buy media.
