Switching to solid state amp?

@bobheinatz 

But the question can I live long term with a SA amp?

You know the answer regarding how you need to go about finding out. : )

If you find the right match for your system, my sense is you may be very pleasantly surprised; and if you get a few amps that don't you'll be wondering why you bothered. 

You haven't mentioned budget, speakers, your tubed pre, or room .... knowing those will help.

@bobheinatz  Hopefully you'll get some traction with this thread. I'm curious also, and would like to learn from those that have done the same.

I don't have your length of experience with tubed systems, but they were thoroughly enjoyable. Over the past few years, I've made the switch to all solid state.

My main 2ch system rebuild started about six months ago. With some recent changes, I'm getting very close to having a solid state system that performs at a level comparably enjoyable to my best tubed efforts. 

I have been happy with the Spread Spectrum Technologies Son of Ampzilla Mk2 (the Wyred 4 Sound version). The Ampzilla 2000 Mk 2 would be an interesting option if you prefer  monos and need more power. I mention both because they don't get much play here and are worth considering should they fit your needs and within your system.

The SST was recently replaced with the Pass XA-30.8.  My preamp is the Pass XP-20.

I'm still keeping the door open for a tubed amplifier and preamplifier, but given the recent major jump up in overall performance the need isn't as strong.

@inna  Can you or others provide more detailed information on why the Gryphon 120 is not comparable to the performance level of the 300, other than the power differential? Assuming appropriate speaker pairing, for each. Thanks. 

@inna   Thanks for the added info and clarification. That's good to know, despite the price differential.

Anyone who has heard both?
