Budget/value SS power amp recommendation


Hello all would appreciate any recommendations for a budget solid state power amp for a lightly used 3rd system to pair with some tube preamps. Budget is less than $500. New, used , cosmetics irrelevant. Initial thoughts are the following but don’t know if they obtainable on this budget.

older belles model
used AVA

Any thoughts or suggestions welcome. Would love to find a sleeper under the radar model or something discounted if it’s cosemticlaly challenged . Thanks

I saw a PS Audio Sprout on eBay for $ 499.   That would be a great addition to your listening needs.

Shad 
Kinergetics Research has a few amps under $500.  They are out of business and a good value sound per dollar. 
I bought an old Marshall Leach Heathkit amp for $250.  I am rebuilding it now,  but it is surprisingly nice sounding.  
Sumo has the Polaris, they run about $300
Rotel, Parasound or Adcom from the early 80's can all be had easily under $500...Adcom 535 is around $200.  
I'm sure a couple of Chinese amps are decent,  Here is a quad knock off by Douk audio:  https://www.ebay.com/itm/Nobsound-Classic-Power-Amplifier-Audiophile-Hi-Fi-Dual-Channel-Stereo-Amp-1...

Rega power amps are low-cost, sound like music to me and often pair well with tube preamps.
