I've been running 803S'sssss for many years and started out with the Big Rotel 1090 (380wpc & 80A peak) with same 1070 preamp.
MSRP on the 1090 was $1999 back in 02-03(?) and I don't think they produce it anymore so you'd have to watch the classifieds. If you do, proceed with caution if your running off a 20A service using a 12 gauge or fatter powercord...the toroidal transformer in that thing is the size of a small pumpkin and you're likely to smoke something
something in the amp like this guy I knew did.
Don't let the magick smoke out!
Marsh Amps where also favorably rated and if I recall had good synergy with the 803S(?)
IMO you can't put enough current flow to the 803. Everytime I upgrade amplification the speaker changes in accordance with degree of ampflication improvement.
