Thanks for all the replies. I took Amir's EQ's to heart using my existing Loki. It helped a lot, but it wasn't enough. I boosted 2k by about 4 dB, cut 8k by about 6 db, cut the 20 Hz by as much as possible (I have two subs, not in that circuit. I also used the preamp treble control to cut by 4 dB. AND, I installed 1 ohm 100 watt resistors on both legs of the tweeter bi-wiring (the woofer is still direct). All of this has helped A LOT.
But the best move was to aim the speakers about 15 degrees outside of my sweet seat. Now, that has helped a lot. My ears stay at tweeter level, approximately. Yes, I can NOW tolerate the Klipsch's without wanting to shotgun them both. (I'd have to buy a shotgun.)
The music (listening to a Chesky 'Symphonic' recording at the moment) is much more listenable. I know the tube stage won't help the response. I just thought I try some 'tube sound' to see if I might prefer it. If I don't like it, I'll return it. IF is ever gets here!
I've rejected the Maggies plan - there's too much glass behind where they'd have to be placed. Keeping my eye out for a replacement set of speakers. Currently, I'm sniffing around the new KLH 5's, but all the pundits who rave about them just listen to the likes of Led Zeppelin and Metallica. I listen to classical symphonic, solo acoustic, some vocal, and jazz. So, unless Amir, or maybe Erin tests them, I'm not sending in my order. I no longer trust any You Tube reviewers who don't listen to my kind of music -- or can test, objectively.
One burned is twice careful.
