It just sounds like it's time to get a louder amp. Screw the critics, man. Start trying out new amps & find the one that suits you best. With today's technology, lots of SS amps can sounds just as great as a tube amp. And to retort to the Marshall amp comment above, why do you think modeling amps have become so popular? With each new innovation, some suck, but some having staying power.
10 years ago, I might've argued differently, but the technology is there & SS amps have come a LONG way.
For me, I've tried both SS & tube amps. I prefer SS amps because they aren't as tempermental as tube amps, they give me a consistent sound at all volumes, & they (generally) don't get muddy in the low end when I crank 'em up. And not to mention, the price is right.
So in short, get a louder amp.

P.S. I have to throw this in there. Last year, I had a wonderful guitarist who was gonna try out for my band. After hearing I use an SS poweramp, he decided not to play with us because I used SS & he was an all-tube guy.
Funny stuff. Purists....you gotta love 'em.
