How easily can you distinguish between different DACs?

@duckworp  - Simply for curiosity sake - what were the $1500 and $25000 DAC's you used?

Nice comparison process between the two DACs.  Many posts about equipment here from folks who don't put the effort into actually conducting direct comparisons or listening tests in a manner that reduces inherent biases, and other posts that state opinions as fact without any reference as to how they reached the opinion, so I appreciate hearing about your methods.

I recently compared two DACs literally side-by-side so that I could quickly change the digital input and two output cables and even though the comparison was sighted, my bias did not win out.  I could definitely hear differences but the DAC that I wanted to sound better actually didn't to my ears.

Like you, I have not heard many dacs. Started with a Jolida glass dac and it really didn't sound any better than my MacBook. Bought a Bluesound and started streaming with that. Heard a slight improvement to my ears. Then on to a Denafrips Ares II. Night and day difference (for the better!) over the Bluesound. All associated equipment stayed the same. Of course, YMMV in this crazy hobby!  I'm content with the Ares for now.  

IME, what better (usually more expensive) dacs offer is a sense of realism. They do a much better job of transporting you to the venue. They're simply better at capturing the nuances, emotions, and the soul of the music. Once you hear that in your system, it's hard to go back to a lesser dac.

Other than that, when it comes to the usual suspects -- soundstage, imaging, detail retrieval, etc., most competent DACs have that covered. If that's what you're primarily listening for, then I agree it's hard to tell them apart ... especially, when you're doing quick A/Bs and wearing your analytical hat so to speak.

Of course, the rest of the chain, and very importantly the streamer, has to be revealing enough and synergistic with the dac to really hear what it's capable of.

Agree with arafig, have spent the last month trying 2 new dacs that have been praised by reviewers at their price point. When comparing the two against my  yggy OG,  Gustard X20, chord 2qute, and a Bitwise Z (which is a vintage sigma delta) using every option available USB, DDC-coax, i2s, AES and streaming with switched optical isolation. I found at first listen difficult to say that any one of them is the clear winner with all music. They all do the expected and some are better at certain things. I like them all for different reasons with different music. The 25 year old Z puts me in the sound stage on some recordings but it is veiled and slow. I still listen to it occasionally and with the right music I am still wowed. I want to be transported to the venue and feel it, not just listen to a hyper detailed reproduction. One piece won't do that, it takes a system.  I had a very enjoyable system 50 years ago, the era might have contributed though, sex drugs and rock and roll.
