I posted this on Bifrost 2 thread but I took the initiative of posting it as a separate topic here in advice sub category. After all it wouldn't be wise to flood the BF2 thread with these type of questions I presume. Apologies if I did wrong! Anyway for what is worth, here it is.. Hi everyone new here but Ive been lurking for a while. Of course I'm a Bifrost 2 owner for quite some time. A great DAC no doubt. I'd like your help/advice on something. My audio chain currently consists of a pair of Focal Solo 6 Be active speakers and an SVS SB2000Pro hooked up to BF2 which in turn is hooked up via balanced to Freya+ and then balanced to speakers and rca to sub. So it's all balanced BF2 -> Freya+ -> balanced Focal Solo 6Be+SB2000Pro. No need for an amp (just yet that is) with active speakers. Have also Valhalla 2 + DT1990Pro and Senns HD600 for headphones. First of all I can't say that I'm not fond of my Bifrost 2 I would seriously be lying if I did. Especially when my Freya + is in tube mode. Their synergy is lovely I find myself listening less and less to other modes of Freya+.. Anyway lately I came across a quad pair of Raytheon VT231 6sn7 tubes which to my surprise (since 2 sets of NOS I had were good but not that special) completely opened up the sound to my ears. Suddendly there was more air on top and less congestion in organs, better stage and slightly recessed mids without losing presence though. Micro, macro details and tamper are amazing in Bifrost 2 I never had any issue to begin with, with virtually the vast majority of genres.. It's just that it was so nice to listen to these tubes because they provided better tonality and musicality to my audio chain, it kinda of reminded me what I've missed in some genres. So I started thinking of acquiring Gungnir A2 or Denafrips Pontus II. I think their overall signature will provide me with some of the things I admired from this pair of vintage tubes and I miss with Bifrost 2. The latter is an exceptional DAC no doubt but sometimes it can be too dark.. I don't mind warm. I love warm and lush.. The way tube mode in Freya+ is presented in synergy with the BF2 is really good because it strikes a great balance between analytical and rich/full body even with the stock tubes. I'd imagine a tad more of these qualities would be more of what I'm looking for.. So my question is.. If I'm to look for a DAC with bigger stage and warmer and slightly more "laid back and congested" presentation do you think that one of those two could be a meaningful upgrade? I don't want a sidegrade,I'd probably keep my Bifrost 2 for its assets, it's a lovely DAC, it can be amazing with its presentation for some genres but I wouldn't mind an upgrade with a DAC with the assets I described. And of course this begs the question. Is it feasible in the sub or close to 2k region? Thanks in advance for any help and for the long post!
