Currently, I have '78 Klipschorns, a pair of JL Audio F113 subwoofers, a Yamaha RXV1800. I am almost going insane with the forward tilt of sound, I'm looking for a more romantic bass tilt to the music. I've eq'd as much as i liked. Thinking the MC275 will fix that. I purchased the Klipschorns from a guy who had a wonderful Adcom amp & all the bass I needed was there- looking to gain that back & then some.

Any recommendations to complete this system?
