Suggestions for the best SS amp for Tympani 4a's

Happy Holidays fellow A'goners,

I need some help with trying to pick the appropriate SS amp to power my Magnepan Tympani 4a's.

I have been using a Joule Electra 80-80 with Paul Speltz autoformers. I know that this amp doesn't produce enough watts to do these speakers justice. I love the OTL sound, but unfortunately, this amp is really not appropriate for the speakers that I currently have.

I would like to keep my choices of ss amps to 4k or so in cost.
My short list at present would be:

1) Parasound JC-1's...used
2) Pass Labs X250...I don't know if this amp has enough juice to
adequately power the 4a's either.

If I make this switch in amps, I want it to be a positive step forward
so any ideas or suggestions would be greatly appreciated.

Thanks and Happy Listening!!
