Solid state - but with that warm, involving sound. As a former five-year owner of a .5 I can honestly say it's one of the best amps I've ever heard - I know that's saying a lot, but I truly miss mine (if it could drive difficult speakers, I'd still own it - I now run a $6K Rowland amp). My guess is that it will be the best money you can spend on your system.
Enjoy, and if you get a .5, let me know what you think.
