        Its a coincidence that I'm in providence for the summer but I have my hilo with me using it as a headphone amp/dac. Please feel free to pm me to discuss your needs.

      I’m going to Seoul. Any must visit audio places there?

        There was a headphone store I liked in Apgujeong Rodeo, but there’s better things to do in Seoul than investigate audio equipment :P

      Just read specs on newish Pass XA25. 50uV noise floor. Looks like it could be a good headamp for planers.

        Spouse: Why does your iPad (JRemote) say it’s 5pm?

        Spouse: You mean we’ve been doing this all day? Oh. Where was that track for hearing jitter again...

        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

      Crane Song Solaris in the house. Stage is great, timbre is mushy (AKM?). Has a gray background. Taste good, but not juicy.

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

      Convert-2 is much better than I had anticipated. I’m frankly kinda pissed off about it.

        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.

      Initial impressions of Lavry Black DA-11 via Eitr: this DAC is the embodiment of @Psalmanazar. It has “fuck-you” accuracy...

        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).

      What do people think of the idea of digitally cutting signal by 3dB to eliminate distortion from intersample overs?

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

        Shiity digital attenuation and/or extreme digital attenuation. Otherwise everything processed digitally would have artifacts...all those DSP plugins fouling up the music.

      I’m so curious why the cold Gungnir Multibit sounds bad. I somehow doubt it’s the resistors. Makes no physical sense.

        Most likely the clocks since it's not oven controlled. Resistors do change with temperature but they probably heat up quickly enough.

        More thinking: if all the resistors in the R:2R have the same temp coefficient, nothing should change. If the rungs and the rails have different temp coefficients, then we would get harmonic distortion.

        As long as one clock is MCLK, shouldn’t the sound be slight out of tune but otherwise distortion free?

        Average clock frequency isn't the problem as much as the jitter. I would say that within the chip the resistors can heat up unevenly. Tbh I'm pulling at straws myself, but the end result is hard to deny.

    I like a detailed/textured sound that is not fatiguing (but I find nearly all detailed sources are) and has good imaging. 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.
