Tubes are like taking care of a small child, they give you wonderful moments but need a lot of care.
If you want the best SQ, IME, it is still going to come from tube gear, unless you spend the very big $$ and go for top ss. OTOH, if you want greater reliability of the sound and no fuss, and SQ is secondary, then ss is the way to go. BTW, Brent Jessee offers a two year warranty on his tubes, something that I took advantage of when I bought from him, I highly recommend it.
