    Hi all,

    I just bought a Bifrost MB and a Modi3 to upgrade my HiFi system. (Bifrost MB Serial number start with a B)
    I have to say that at first, the improvement over my Cambridge Audio 640C v2 (modded) was not obvious. But now the Bifrost has been on for 3 days, and the performance improvement is now clear:

    - Bass is much more articulate, less bloomy (which also means less meaty acoustic guitars xD). It really becomes enjoyable to follow bass lines and cellos without the relatively overwhelming un-controlled bass I experience with 640C v2 (also true, to less extend on the Modi3)
    - Mids are less shouty
    - Highs have more texture and extension (more subtle this one)
    - Stereo image and localisation is a tiny bit better.

    Modi3 does not even compare, but that was expected.
    - Modi3 is much less transparent, and seem to lack a lot of high frequency details and snap compared to the Bifrost/640C.
    - I was not able to use Schiit's power supply, and used some other. I got surprising differences by using various ones.

    Note: I experience some important hum on the Bifrost when pluging the SPDIF from the 640C. It might be a ground loop, to be investigated. At the moment Optical and Usb inputs on bifrost give same performance to my ears (usb is noisier if I push the volume, but not a concern.. I might need to play around with the windows audio configuration).
    I'll post a separate detailed review once all set.

    I just joined the Bifrost Multibit club, upgrading from a Modi Multibit/Eitr combo (v1 firmware). The rest of the setup is a *heavily* modified Crack and Atticus cocobolo. I guess you could say I like it warm. This is effectively* my end-game (*until I can find a better job that pays me a lot more money).

    It's "only" been on for two days, but I have definitely noticed that the stereo imaging/separation/soundstage is much more precise and spacious. In my experience modding the Crack and building a little regulated PSU for the gamma2, power supply upgrades generally improve separation and staging, and as I understand it the Bifrost Multibit is basically a Modi MB with a fancier power supply and analog section. The Eitr/Modi sounds a bit bloated, compressed, and smeared in comparison (but is still an excellent DAC for the price--it's now hooked up to a Chromecast Audio and Oppo Blu-ray player which go into my speakers). I am a pretty big fan of the idea that this thing is upgradeable; I know there's an even better USB input next year.
