I have the 403. Incredible for 2-channel music and runs all 3 front/center for movies. Using 2 S-1500/4 amps (150w/ch x4) for each 2 surround and 2 overhead speakers per side. Krell is still closing out the S-1500 amps and you can order any number of channels from 1-7. The 3250 is a great amp as well, but probably harder to find.
It's critical that you have the necessary power circuits to supply these big amps. I installed a separate 100-amp panel for my theater, with 8 individual 20-amp circuits. One circuit is for the 403, one for the two S-1500s, 2 for my JL F113 subs, 3 for each pair of GoldenEar Tritons, and one for the components and display. You can choke these big amps by placing them on a circuit with insufficient capacity.
GoldenEar Triton One speakers (6, for front, side surround, and rear surround), GoldenEar SuperCenter XXL center channel, GoldenEar HTR7000 overhead speakers (4), JL Audio F113 x 2 (subwoofers), Krell Foundation pre-pro, Krell EV403 (front 3 channels), 2 x Krell S1500/4 (one for each side's 2 surround and 2 overhead speakers), OPPO 203D (4K, Blu-ray, SACD, DVD-A), Calyx Audio DAC24/192, MacMini w/ 2TB drive (server), Purist Audio interconnects & speaker cables, Sony XBR-75Z9D monitor.
