        My thoughts are: what’s the clock implementation? Jitter? USB as USB audio or something else?

        Knowing Schiit, I'd put it up against any Focusrite or PreSonus interface. I'd use it, but I like having inputs and outputs as well as ASIO drivers.

      Using @purr1n’s 37Hz bass note in Doin’ it Right for testing. Great tip!

        Great tip indeed, the fact that it's a song I love listening to helps. For something more "violent", I've been using Billie Eilish's xanny lately; 30/31Hz at its lowest, hahaha

      Sad(?) Fact: I enjoy figuring out what I consider to be ideal audio reproduction more than I enjoy listening to music.

        I fall somewhere between I think. I don't necessarily chase perfect reproduction of source material, but do have fun seeing how much "better" the listening experience can get. Shame 90% of my library is crud haha.

        I've always thought that the difference between an audiophile and a normal music consumer is that, to the audiophile, all recorded music is acousmatic to some extent. Audiophiles are keenly aware that changing the manner of reproduction can dramatically affect the way the content is perceived.

        I’m out of the headphone hobby forever. I sold my Sennheisers and just use a Porta Pro and HD 25. The Porta Pro is just as far from speakers if you get a 6.3mm adaptor and plug it into something real.

        I compared using the most sensitive-to-jitter track I’ve found and I can’t hear any difference between ifi and batteries when listening with speakers (headphones are often more resolving but not really to jitter). FWIW, my wall warts are far away from DigiOne

        Seems timbre is not so mushy now. But still sounds compressed in the macro dynamics. Volume control was not at issue.

        It has a moderately bad noise floor that goes up with the volume trim, limiting the total dynamic range. I can *always* hear it regardless of volume. I’ll measure it later. It’s not as bad as PSAudio DirectStream, however. EDIT: on the bench the noise measures way below audible levels. Yet I do hear noise with Convert that I don’t hear with other DACs I don’t here it. SNR = -80 to -113 dB according to QA401.

        It is also bright. Universally, regardless of transducer or program material, It sounds tipped up at the end. It sounds flat elsewhere.

        If it's not TT2, never bother. Applies to every pre-dave things imo. Chord started to get things (relatively) right since dave. In terms of only SQ, I prefer qutest -- presumably slightly improved hugo 2 -- to og TT. It's at least $700-900 good (not 1.9k good) to my ears.

        No where do any of those measurements suggest audible levels of 3rd order distortion.

        It’s OK to not like something, but let’s be real here and not start reaching.

        Plus if you are twisting measurement results in such a way, I have no clue why you’d want to try the Adagio, which measures much worse. (Plus Pavane Lvl 2 or 3 will get same sound for less, unless you want the preamp part).

        Digital attenuation has artefacts. If you can't hear them your system is not resolving enough.

    I like a detailed/textured sound that accurate timbre. I listen primarily to older jazz, piano trio, bebop, and classical. Sucker for a bit of warm tonality provided it doesn’t screw up timbre and imgaging too much.
