I’ve had both the Parasound A21 and Classe CA2200 .. I liked the Classe better.. More detail.. That said I’d choose the Parasound.. Company still doing business.. Just in case you need an amp repair.. The company that purchased Classe I had a bad experience with them recently.. Forgot their name as of now.. About 1 1/2 years ago I’d sent my Classe in for repair because I was having a popping sound.. Thought for sure the amp was the problem. Turns out it wasn’t the amp.. So I had them just check it out to make sue everything was good while it was there and send it back.. I paid them.. all good.. Then 1 1/2 years later they charged my card again.. Without any notice.. Got it resolved through the bank but still, pretty shady business.. Kept my info stored then dinged it
