For you people who like holography, nothing better than to use the LEGENDARY BOB CARVER AMPS such as sunfire or carver preamps/amps WITH DAKIOM feedback stabilizers. All my ohm's eminent tech, magnepans are all run by these combinations. Since I am a processor fanatic,I like to tweak using dbx, peavey, bbe to add to the juice. I don't know why ohm did not stick to the old pyramid designs, just because many of their craftsman/cabinet makers retired. I hate the new cabinet designs, but would like to have the new drivers. I can't believe i owned bose 901, 601's in the 80's only to wake up to reality and listen to REAL music coming from a TRUE loudspeaker, OHM WALSH series. I LOVE MY OHMS as well as my maggies.
