remember, 80% of the sound is made in the first 20wpc.
if you are not yet a brand snob, the BC Crimson stereo amp is a real over achiever and will supply enough power I suspect for your transducers.
I have no dog in this hunt what so ever but have heard the crimson recently and thought it an exceptional amp at well above its price point .
so I’ll also say ‘plus one for the Carver crimson 75wpc stereo tube amp’.
at well under $3K, with as was said, a 30 day trial… tell me, exactly what can you possibly lose by giving one an audition in your own room?
it beats buying on speculation AND adds to your Experience.
it is a manual bias amp.
has 4 & 8 ohm taps.
RE Auto vs manual bias
this is pretty much a pick ‘em debate. it lays in the who’s making the auto bias amp IMO.
on the other hand, a manual bias amp enables the ‘tweeker’ in us the opportunity to check and recheck bias every 12 minutes or so. loll
usually manual biased amps as has been said, hold bias well. that ins once they’re run in some.
AS Ralph said, once you hear the effect tubes have with detail and so forth, you will either dig them/it or not. if you do like the presentation, obtaining a preamp that as well is glass topology will enhance and ordinarily escalate the overall performance level and bring more ‘life’ or ‘reality’ into the room.
tube amps generally capture more reality given the same dolar amount as SS amps.
in other words, it takes an lot more money in SS to do what tubes do for very often much less.
again, IMHO.
as for which tubes are still out there? well there is a finite supply. especially in New Old Stock (NOS) tubes.
don’t let that stop you or scare ya. therre are still enough solid choices and availability to enjoy some occasional tube swapping or ‘rolling’.
Google is your friend so use it. I think there is a pretty good primer on the sound of this or that tube called “Joes’ tube lore’… I think. he is mighty close on what many of those tubes provide sQ wise.
once you’ve settled on tube amps, if that is your choice, there are tons of folks here who have a wealth of EXP with various tube brands, and types.
just ask.
it may seem daunting but really its not.
good luck!!
