Which SS amplifier has similar sound as the LTA amplifiers?....

LTA is certainly hard to beat. this might work and save you some $$. maybe call Frank

Thanks Jmolsberg, the AVA control amplifier looks like an excellent option. Dan

There is no SS amp in your price range that can match an LTA offering. My CODA #16 comes closest but at 13K. My ZOTL40 is a care free, maintenance free amp. The tubes in it will probably outlast me. I would check out the used market.

First Watt F7 or a used F5.

There’s a used Valvet E2 available here for $1850.  It’s Class A, but it’s small so isn’t as much of a space heater as the larger, more powerful beasts out there.  Read the reviews if you haven’t.  Best of luck.
