Tube vs solid state (with all apologies)

Tube vs ss.
 Mids and high frequency to me are much sweeter with tubes. Ss is most dominant in the bass. Bi- amp your speakers have the best of both worlds 

Tubes if you are a hobbyist and like to fiddle around and roll them and deal with problems (how often depends on the amp). You can get a great sound for solid state with no hassle. My motto KISS.

When it comes to reliability questions in the tube vs. solid state argument, I can only say that over the years I've gotten more reliability from my tube gear than from my solid state gear. I ain't gonna name names here, but if pressed I might lose my composure and begin to blab.

Use tubes wherever you need to amplify a signal and wherever you rectify a signal. 

@edcyn - clearly you are the exception. Please let us know the SS amps you had problems with and the tubes that are super reliable, long lasting and maintenance free (for decades without periodic tube replacement).
