Divo: I have the Mk 1 Super Eclipses. Dopogue: I tried the Gallos pointing straight forward; woofer in, woofer out, etc. The upper mid forward thing is lessened by the toe-in. (Side wall reflection makes it worse, maybe
.?)
I think I figured out the problem. I re-tubed the Cary SLAM-100's and noticed the new KT-88's biased lower on their own than the previous set. When I brought the new tubes' bias up to the former level, the upper-mid forwardness came back (to some degree). When I backed off the biasing, it is greatly reduced. (I will have to check the Cary website to make sure I am biasing correctly.) Who's to say, at this point, whether the major difference comes from the new tubes themselves or the lower biasing? Perhaps both. Maybe lower biasing more will sound better yet.
Without this forwardness and with the greater integration, the result reminds me of a top-notch monitor with a bit of extra lower extension: open, detailed, images like crazy, engaging, etc. Now, if I could just fill in the bass more.... (The Super Eclipses have bass and dynamics that help lend impact and scale.)
Has anybody tried the Gallo sub-amp to co-drive the woofer vs. another separate sub from another manufacturer?
