I cannot speak to long-term reliability but if you are looking for well-reviewed SS Class A without the enormous price tag, you might try Clayton Audio.
Or you could go for the older Forte 4 amps...you could buy 2 for 1500 or perhaps less...and monoblock. End up with upwards of 200 watts of pure Class A power. Good luck! Sounds like you've already got a good choice.
