@moose89 your comment here "Mancave is treated, speakers and me complete a 6’ triangle" is kinda throwing me. Can’t imagine, and with those speakers. I’m a former owner of SLI-80, fwiw. Selecting the right dac in your case is critical, imo.
As for dacs, I can share recent experience with MHDT Orchid w/upgrades (all possible tubes), current Schiit Bifrost 2/64 and Border Patrol SE-I now too. I’ve enjoyed all three of these dacs for different reasons. Each sounds different.
For anyone to help more - if I may suggest, you need to share a little bit more about this six foot triangle space you are listening in. What are the actual dimensions of this room/space, walls, width, ceiling height? Wow, and how close are you sitting to the Cornwall speakers? (i.e. really, a 6’ triangle?); share more details...
