Alright... Asgard 3 and Bifrost 2 in the house. Most of my listening was with the Focal Clear Pro's (except for gaming I use a AKG K702. Focal's are too nice to put a mod mic on imo)
Unboxing Bifrost 2 definitively feels more substantial than the Modius. I enjoy that it's USB B and that it has it's own power. Even the button to change sources is more solid. Similar look but more solid all around.
Upon first listening I didn't notice huge differences but I know a lot of people here mention mutli-bit DACs take a while to warm up. I think it was 2-3 hours in where I really started to notice changes. Bass has more texture and was less one note (not any more bass output but easier to tell what instrument made the sound. No real advantage here with EDM but I listen to a bit of everything), this already had me checking out a number of tracks I know well.
Other fine details that I had to focus on in Modius seem to jump out at me more with Bifrost 2. It's like 2 photos but one the auto focus overshot where the other one is tack sharp (not sure how many people are also into photography but when you nail focus it's very rewarding). Even hearing things in the background that aren't intended to be part of the recording "did he just hit a button on his shirt?" type moments
Soundstage is a bit more 3D but is really dependent on the track. Some tracks just sound left to right, others I can hear all around. Which lead to me trying this stack for gaming. WOW I can tell distance so well now, I felt like I could see through walls. This actually has lead to me dying more in the past few days (knowing where guys, leads to me pushing but I keep getting outnumbered). I'm too in shock with how well I can tell where people are that I'm forgetting to communicate with my team (my own fault). Tonight going to play again and try and tell them "Hey I know where they are, follow me".
Overall Bifrost 2 seems like a great upgrade from Modius. A lot of my friends likely would never justify a DAC that costs this much and that's okay, but for me I 100% appreciate what it offers. If anything it makes my want to try the Yggdrasil one day...
Probably going to keep the Modius and use it in my parents stereo I'm helping them build in the next few months. Schiit everywhere
