I have tried, but have never found an affordable solid state amp to compete with a very good valve amp. I listen to a lot of acoustic music and vocal music. I used to stick to solid state because of the hassle of valves, but I was always struck by the fact that at a live concert there was a certain beauty to mid-range tones and a certain roundedness to high frequencies that was not reproduced on my system. No amount of tuning could ever get it right. Then I tried a pretty good valve amplifier and I instantly heard the hint of what had always been missing. I then went on a quest of trying valve amps and tube rolling until I got what I was looking for. Since then I have tried a number of solid state amps (in fact I own a Plinius SA250 Mk IV to drive Thiel 3.6 in one of my systems), but the only ones that get close do so in a way that sounds artificial in a way that my tube monoblocks do not (but my tube monoblocks do not quite drive the Thiel 3.6, I must admit, but a bigger valve amp probably would). In the end there are undoubted downsides to tube amps, and so the choice comes down to your musical values. I can live with my beach house system (ss and dynamic speakers) for a short while, but the only thing that gets me close to the live experience is valves and panels. Curiously, I am not so adamant when it comes to CD output stages or preamps - I can put up with solid state in these departments quite easily, and I do not like the added sweetening people sometimes use valves for in low-level stages. It is in the output stages of power amps where I believe solid state is not capable of being faithful to the original sound.
