There are a number of good amplifier manufacturers still around that do traditional solid state designs. However, they are starting to get expensive for the really good stuff.

The future of the industry is in PWM digital amps. Some folks may scoff at that, but those same folks (or their fathers) were probably scoffing at solid state gear back in the 60's/70's and saying that EL34's or 6550's or KT88's were the be-all end-all in amplifying music.

Much like the current state of tube gear vs solid state development, we're seeing a shift in "high end" to the older more trusted technology and the masses are slowly catching on to the newer/cheaper/more efficient stuff. History tends to repeat itself.

Cheers,
