i’ll second the Bryston Amps they have been making gear for decades and stand behind everything they make. They do a huge amount of business with the pro side that’s why they can back their stuff with 20 Year warranty as they have a rep to stand by and build for punishment on the road. you would be surprised at home many bands travel with Bryston gear for their live events. that said the newer stuff has a good rep for durability and sound quality.
Just a side noet when I started out in Audio 20 years ago I had a 15 year old bryston pre-amp that needed work I sent it to them and they completely rebuild it upgrading all the old inputs to gold plated ones and updated the transformers came back better then new. They will be here 30 years form now...
IMHO they build better quality then Classe for the money. Sound wise that’s user defined.
