Started upgrading from a Yamaha rx v659 and a set of cerwin vega ls-12s in December. SVS prime towers, svs prime center, dual svs sb1000 subs and def tech promonitor 800's. Yamaha mx-2, Yamaha m80, denon poa 800, anthem mrx 310. Rega rp1 w/upgrades, lounge audio mkIII preamp. Plus running dedicated electrical circuits for the system. Pretty happy with the way it sounds. Not high end but it is a good start.
