Yep every reciever that has any kind of line level out is really just a pre-pro in disguise, PLUS they throw in those magically rated amps. Wow you've really uncovered quite a conspiracy.
If its a receiver with pre-amp outs, then yes its a pre-pro in disguise. Just ask Outlaw as they marketed their own 1050 and Sherwood R965's that way and continue to do so for the Martanz SR5005.
FWIW, your Bugatti comparison is pretty lame. Outlaw, by definition, is not and never will be a Bugatti type product. In this instance, comparing a Miata to a BMW Z4 is still a stretch with its approximate 2x price factor.
