Switching to solid state amp?

I would also recommend you take a look at Plinius amps and/or Integrated. This caught my eye today:

If one wanted an Integrated that sounds some what tube like.

My Quicksilver amps were reliable and sounded great, but did not have the level of grip the Atlas has on the bass. The change in the bass really made the sound lock in for me.

Good luck with your search and have a listen to the Aesthetix Atlas.

As another poster suggested, Nagra is also an option but the price is quite a bit higher. 

@bobheinatz , what sort of problems are you having with your current amps? Do you think they can't be fixed so they'll hold up?

There's a pair of Clayton M300s for sale here now that would be worth a look.  Thinking Class A amps might be your smoothest transition to SS.  Best of luck. 

Ralph I had my current amps worked on recently and one of them came back dead.  So not reliable. I will need to replace.
