So you're after "never mind the quality feel the depth"?
....and the Herons are fine for real music made by real instruments!!!
Seriously though - thanks for the compliments. I just count myself so lucky to have the amp. I think the biggest compliment (inadvertent) was from HenryT, when he asked whose recording of Mahler 8 (albeit only the opening flourish) I'd just played - and then couldn't believe it was the same one he has!
I guess a dedicated sub will always go lower than an integral speaker, but I'm not sure you're right about the "whole octave" - the Herons go down to 28Hz (before any room reinforcement), and there's only half an octave below that before you cease to hear anything. I was at that Infrasonic experiment a few weeks ago, where they were transmitting enough 19Hz into the room to flap a programme held at the end of the resonator a good couple of cm, and it was completely inaudible (at least half the people in the hall got it wrong whether it was on or not).
I wish I'd played a whole number of other pieces - it just keeps on getting better. In particular I've just played the finale to the Rite of Spring (Tilson Thomas/SFSO), which I played at Robbos, and the bass drum beats are fantastic - they really shake the settee (and are far more lifelike than when at yours

) - there's thwack and timbre and decay :banana: . We also didn't play any female vocals, which really are absolutely stunning.
The other really interesting experiment was playing with interconnect

rolleyes: ). I've normally been using my standard 2.5m NuVista I/Cs. We also tried some 1m Acoustic Zen Matrix Reference balanced, and Towshend Isolda balanced. In previous tests the balanced has come out clearly ahead of the RCA, so here we got - NO DIFFERENCE (or as least nothing a blind test would come close to detecting; surprisingly the RCA may have been a bit louder than the balanced). Later on we also tried a passive (Lee's DIY) attenuator with cheapish RCA connections, and still little difference. Even putting in an active component (Lee's Art Audio pre-amp) made very little difference other than volume - other than maybe a very slight loss of ambience (which was a tad more pronounced with Sideshow's EAR pre). So maybe this is vindication for the engineer types who say that magic I/Cs are not required if the components involved have properly designed input/output stages. The biggest difference, and that still wasn't huge, was a bit of a clean up at the top end with a some mains conditioning (either Robbo's Kimber stuff or my Trichord block).
As for the problems with the chamber stuff - the major problem recordings were digital recordings from 1982-1984, so it could be just that the amp was showing me just what was on the disc

. We did get a definite improvement switching the amp from the symmetric mode I'd been using up until then into single ended mode, when things became a bit warmer and sweeter (if a bit less tight at the bottom). So with that option things are looking pretty decent.
Upgrades over!!!!! :boogie:
(...now what was that about a TT?)
