    Good questions. I originally used them for two setups. That’s no longer the case, but I’m keeping both “just in case” I want to put together a second rig again.

    I could definitely be happy with either the 1541 or the ADI-2 DAC. I actually tried to find a convenient software PEQ to use with the 1541, but found nothing I like (closest thing I found was using Apple’s AU plugin with Audirvana, but I’m really looking for a lightweight system-wide solution).

    I’d say that the decision should be based on how much your system benefits from EQ, since that’s the ADI-2’s killer feature. For, say, the Andromeda or the PMx2, there isn’t much equalization needed. For the HD800 or the PM3, it’s a game changer. For the HD600, it’s a bit of a wash. For speakers, I think it benefits most systems by helping fit room acoustics.

    As for the Gungnir Multibit, it doesn’t sound different enough to me from the 1541 to justify keeping. Yes, I tested volume-matched, with a switcher, and for both short and long sessions. They didn’t sound identical (and I have stronger evidence than “I said so”), but the differences washed out in seconds as my brain adapted. I’m also probably the only person who cares about this, but I found the Gungnir Multibit’s (and Yggdrasil’s) relay click unbelievably obnoxious. It goes off all the time when the USB input has no lock (i.e., connected to a sleeping laptop), and it’s plenty loud enough to echo through a quiet house at night. And since you’re not “supposed” to turn off multibit DACs, I’d have to remember to change inputs all the time, which annoyed me. That, coupled with the 1541’s vastly better feature set, made it a no-brainer to sell the Gungnir Multibit.

    The only time it bothers me is when using it for tv, as commercials are apparently recorded at different bitrates. Never hear it listening to music.

    Do you have a speaker system on hand? I'd be curious to hear which one you prefer through speakers.

    I don’t have anything high-end, only a pair of C-Notes I built this summer for my digital piano. I do like using a bit of EQ with it, but generally leave the mid-range (where most piano-playing occurs) alone. I can switch to the 1541 for a week or so and report back what I think, but it’s currently running nicely off the ADI-2.

    I have a question about the ADI-2 for MAC osx users, when you connect it does it disable volume control on the computer or can you still adjust it on the mac?

    Also does it get warm?

    The ADI-2 series disables system volume control. Some DACs supposedly (?) have a feature which allows system volume control to affect attenuation on the DAC chip itself, but I'm pretty sure RME uses a custom level control which cannot (easily) be changed that way. You need to use the external volume knob.

    Yes, it gets a bit warm. Nothing crazy hot.

    The top of my ADI-2 DAC's case is 15°F warmer than the desk it's sitting on.

    Does it do that on both MAC and windows? I know some seems to work fine on windows and others on MAC.

    I had a benchmark with disabled it, but now i have an aune which i can still use the volume control.

    Is there any reasoning behind disabling the volume control on the computer? I find it almost a must have when using it with the computer.

    ADI-2 DAC has a remote control. I’m quite fine using that instead of the vol buttons on my iMac keyboard.

    Also the remote has 4 configurable buttons, that’s quite cool for a control freak like me. Here’s my buttons...
    1. Bass and treble on/off
    2. Loudness on/off
    3. EQ on/off
    4. Change screen view

    The Mac's system volume is locked when using the RME, but the application (like iTunes) can still control the volume.

    On a side note, if you feel this DAC/Amp is worth of recognition with a Golden Schlong award, head over to the Club Room and voice your thoughts. Of course, you can also comment on all the other great gear being discussed.

    Just remembered not reporting this (unverified) tip to this thread.

    After repeated self-experiments, I found that balanced outs of adi-2 dac were marginally better than unbalanced ones in terms of micro- and macro- dynamics. Note that the difference was much smaller than OG Gungnir Multibit.

    Anyway, for that reason, I've been using this cheap transformer between my amp (BW2) and dac (ADI-2 dac) for four months.

    I didn't want much for such a low price and made-in-china. Also as expected, it increased distortion and added coloration. My perception includes the followings:
    • Slightly reduced micro-dynamics. This loss was canceled by the benefit from balanced outs.
    • Tad grayer black-ground. But it feels like the background having natural-ish gradation.
    • Slightly rolled top
    • Looser bass definition
    These seemingly bad things surprisingly went well with my rig (and my preference). The total sound became more relaxed. DS-glare was also fairly reduced -- still there, but much less annoying. In other words, overall change helped me connect to the music more closely at a cost of a little loss of technicalities. This is a good thing. At least to my liking.

    Higher quality transformer like Jenson might work better.. or not. Dunno.
    The fact is that I am enjoying this unexpected and pleasing synergy a lot.

    I just checked, and volume control remains enabled in Windows 10 with the ADI-2.

    I imagine the theory is that OS volume control is lossy, and you should use whatever the DAC/preamp manufacturer gave you instead — presumably, it's higher-fidelity. Of course, most DACs implement their own volume controls digitally, so it probably amounts to the same thing in the end. ¯\_(ツ)_/¯
