I have always used tube amps all my life but recently started looking for a solid state amp because of the growing unreliability of currently made tubes. There are some solid state amps that can make tube enthusiasts happy because they will sound a bit like "tube amps", but the problem is the price, as you have to pay considerably more for a good solid state amp than for a decent tube amp. For me, for example, Vitus Audio SIA - 025 is a wonderful amp I could replace my tube amp with any time, but the price is very high.
