I feel that you can get a nice sounding, powerful solid state amp in the $1,000-$1,200 range (used) where you would have to spend double that to get an equally well built tube amp.
I really enjoyed my Classe CA-200, and I also like the Parasound Halo A21, McCormacks and Conrad Johnson amps.
My Primaluna Prologue 3 was nice but felt more like an entry level tube amplifier and not as highup the chain as my Classe CA-200. The Primaluna also ran out of steam at about 80% of the volume I wanted. It also couldn't control the bass like a hefty solid state amp.
Tube amps can require more maintenance and swapping tubes can get expensive. My Primaluna popped and blew smoke one day while just being turned on.
Also, I like to leave my equipment on 24/7 so I don't have to wait 10-20 minutes for itto warm up and sound its best; you can't leave a tube amp on constantly.
Many people say solid state amp, tube pre amp is the way to go but I have never tried this set up.
Tubes look sexy though, and they can impart a certain richness and texture to the music which can make it sound a bit more organic, but at the same time, a good solid state amp can sound rich and full bodied also.
