Solid State. Tubes threw too much heat, couldn't grip my Magicos well enough, and many great SS exist now that have delicacy and spaciousness of tubes.
To my ears even-order harmonic distortion (tubes) is overall more musical than odd-order (SS) but tubes are limited in damping and the grunt required by many of todays modern speaker designs.
Therefore my plan has been to use tubes for the itty-bitty phono signal and turn it over to SS for the heavy lifting.
If I ever were to do a second system it would be all SET with the required high efficiency box speakers. (At the speed I put together systems don't hold your breath.)
just saying 'solid state' leaves a very incomplete picture.
over a 20 year period I went from mega solid state -> OTL mid powered tubes -> mega watt tube/ss hybrid -> minimalist modest powered solid state with zero global feedback and minimal parts count that sounded 'like tubes' -> to mega watt solid state with zero global feedback and even lower parts count in the signal path.
my experience with OTL tube amps showed me that tubes can be linear throughout the frequency range and not rolled off or rounded. but the right solid state could also do that and yet have a lower noise floor and greater dynamic grip....given the right speaker to drive.
if I listed my top 10 favorite amps 8 of them would be tube amps.
I like solid state amps that have tube attributes. and that is what I use.
I use a solid state pre with those same perspectives. and low noise floor is particularly advantageous with a preamp.
