BI-amping Rti-4's: Mosfet vs. Bi-Polar

aaharvel

I have a pair of Rti-4's wired to an Adcom 5300 MOSFET amp, and an Adcom 7300 60x5 bi-polar amp wired to my center, side and rear surrounds, with a Harman Kardon 235 serving as the receiver, pre/pro. My question is regarding listening to music in 2ch. mode with just my rti-4's with subwoofer.

Adcom's midrange tonality is nice (the 5300 amp) - yet the high notes are kind of in your face. For home theater- the Adcom's bright/aggressive sound is of no consequence, but I listen to music first and foremost and prefer a warmer laid back sound that the Adcom isn't giving me. Is it because it's a Mosfet design instead of a bipolar one?

Question #1-
Which amp design is better for 2ch. music playback if you much prefer a warm/laid back sound from neutral speakers (rti-4)?


BI-AMP option- (Midrange to the Adcom, Tweeter to the H/K receiver)

Bi-Amp Scenario #1- I could wire the tweeter to the h/k and let the 2ch. mosfet adcom 5300 (80 wpc) play the 5 1/4 inch midrange- do you think that will improve the sound?

Bi-Amp Scenario #2- ... or should I instead hook up the 5ch. bi-polar 7300 (60wpc) to the rti-4's woofer while wiring the tweeter to the H/K?

The reason I'm thinking of hooking the tweeter up to the H/K is because Its widely accepted that H/K has a warmer sound in it's highs than Adcom does. I haven't tried either yet- cuz i'm afraid i'd blow the speaker.

Any feedback (specific) would be much appreciative.

danger boy

i've never heard of a bi-polar amp. where did you find that?

My experience with Adcom amps.. is that tend to be bright... change out the Adcom for a different amp.. or change the interconnects out.. that might tame the brightness.. also make sure the treble on your receiver is set to flat.. center position. cranking it to the right will add tremendous brightness when mixed with the Adcom.

they're called Bi-Polar transistor amps- the ones Adcom used to make.
