@peterf6 I was close to buying a single Aegir as a small backup lower power stereo amp to my tube amps on rotation duty, then discovered several references through various sources about how running TWO Aegir amps (XLR/Balanced) is reportedly "so much better", functionally, musically. And, I don’t run an XLR capable preamp, RCA single-ended only - so the idea stopped there. My 6SN7 tube preamp isn’t going anywhere, so back to RCA cable options only for me.
Ended up going for purchase of a used higher power stereo amp that I’ll upgrade, similar to what @jl35 did with the Odyssey situation. Would love to have sprung for a pair of Schiit Tyr amps - but not worth the cost to me as backup amps. However, IF two of the Aegir amps could function in RCA/Single Ended cable mode instead of the XLR-only requirement, I might have tried a pair of Aegir amps. No dice.
