500+ Head-Fier
The Bifrost 2/64 seems like a great choice.I originally got the 1990 for use as a mixing headphone and they're definitely great at that. They also sound incredible with my Nord Stage 4. My next upgrade is the Bifrost 2/64. I had the original Bifrost 2 and loved it but I did think it was a bit too warmly colored. What I'm getting from 2/64 review is that it's not as warm and improves in other areas which sounds perfect. Listening to the 1990s I wouldn't mind a bit warmth, but not as much as a tube amp which is a bit too thick for my liking
My desktop system uses a Modius AKM DAC, with an Asgard 2 amp. The Asgard 2 is about as close as one can get to tube sound in solid state (Class A, single-ended MOSFET, zero negative feedback). I liked the 1990 a lot with a Bottlehead Crack, but I still preferred the Asgard. I get my best sound with the 1990 plugged into the headphone output of my exaSound e32 Mk-II.
