Around the mid ’80’s Bob Carver made some very good sounding amplifiers with an unusual and very light power supply. He challenged critics to hear any difference between his M1.0 and an expensive high-end tube amp (forgot which one) - and he proved his point- they couldn’t hear a difference.
Subsequent designs like the PM1.5t and PM2.0t were made for the pro audio industry and they were immediately accepted for their light weight and superb audio quality - and now you can find these used on eBay for around $500.
I don’t think anything these days at any price will give you better performance than these vintage Carvers- even at at ten times the price.
Only down side: A little bit of fan noise, but in a home system where these will be barely whispering, you can easily disconnect the fan, like I did with mine, running the woofers in a bi-amped system.
