Need help. I need recomendations for amp, or amp/preamp

Based on the design type alone you’re going to want a solid-state amp of 100 WPC minimum. 

Not a mass market receiver 100wpc. Quality power. 

Price could range up to $2500. Can you give some suggestions for "not mass market..quality power."

There’s a nice McCormack DNA 125 with the coveted SMcAudio upgrade that bring this amp to near SOTA performance levels available on USAudiomart for $1750, which is a relative bargain given the pricey upgrades we’re done in January 2022.  Pair this with something like a Schiit Freya (whichever version suits you best) and you’ll have a very nice setup.

If you might prefer an integrated there’s a Hegel H160 also on USAM if you can stretch a little, but I’d go with the pre/amp combo above, and it’s cheaper.

Musical Fidelity M5si or even the M3si or a Rogue Sphinx.

Take a look at a Schiit Ragnarok integrated. 60 watts a channel at 8 ohms and 100 watts at 4, all solid state -- AB, not D amplification.

I don't have this model, but have been very impressed with the sound quality of the amps and preamps I've purchased from them.  And, in your case, it leaves a healthy amount of money in your pocket. They also have a two week trial period (starting after you receive it) with a 5% restocking fee if you send it back.
