finding a solid state amp to replace a tube amp

I've found Pass and Rowland to possess "tube-like" qualities. They still sound like SS though.

I would look first at CJ SS amps, as they are products of the same design team. I use a CJ 350 myself and it is a great amp, although not cheap. But as noted above , tubes and SS have their own sound. If it is to be a back up why not try a different flavor, I am a SS user but occasionally use a tube hybrid pre amp, it gives a different, but equally valid, take on the music.

Don't know about CJ treble response but you might like ARC'z 100.2 and D400MkII amps - both are considered to have some tube like character.

Bel Canto eVo should be on your short list. I replaced a tube amp with an eVo. Needed more power, but did not have the budget for high-powered tube. Including both tube and SS, the eVo has turned out to be one of my favorites.

In this case, I agree with Stanwal.
