@unsound thanks for that info! That narrows down the selection of amplifiers somewhat. Based on those numbers, I ordered a PS Audio GCA 250 over to audition, which is supposedly stable down to <1.5 ohm
@jafant , thanks for your input. I don't have any particular hybrid amp in mind. I'm just currently using a set of monoblocks of which the first 5 watts are pure class A. They switch to a/b mode when more watts are required. Sounded great on the 1.2, but seems to lack a bit with the 2.4.
My primary source is a pi2aes streamer into a Schiit Yggdrasil dac through an Audioquest carbon aes/ebu cable. Speaker cables are Kimber 8TC, interconnects are Kimber PBJs. The Schiit dac is very good at separating instruments but a bit forward sounding, so I'm curious to see how it matches the PS Audio GCA, which is supposed to be on the leaner side for a class d design.
