I’m currently running some xpr1’s on them that I’ve had.
IMO, when people have a lot of money in their budget, they will probably buy McIntosh or Bryston. If they don't want to spend that much money, then the next price class would be ATI, Parasound, Anthem, NAD, Rotel.
Below that price class would be Emotiva, Buckeye and some other less expensive amps.
So talk to your dealers to see what kind of prices you are willing to spend.
