Well, it just keeps getting better. Sound stage focusing up nicely, sub is turned off for two channel, and the bass output is amazing. I am still stunned at the difference the amp made.
But...there's always a but...the extreme highs are still too much, and not accurate. Most noticeable on piano notes for me. There's a shrill-tinniness that I can only ascribe to the ribbons-style tweeters (or to my ears).
Audiolabyrinth, I am somewhat surpised to hear that, since the PSB's sounded great to me. I am also thinking that the environment they were in at the store (large open room, no boundaries to the side) would make them sound worse than in my 'real life sized' 12X19X8 room. As I've said before, and hence my quandary, the Infinity's don't give much away to the PSB's (except as the differences in room would effect the PSB's), but they don't sound as good. It's just that I don't hear $3500 difference in price, so it's a hard leap to make.
I may try the tissue-over-the-tweeter trick I read about here and elsewhere. But I would be open to other recommendations, either of speaker upgrade or other tricks-n-tips. There's no doubt the Odyssey is bringing out the best in the Kappa's, but they are hardly the last word in sound. Given that I like the sound of the PSB's, and the size works aesthetically, bass extension isn't critical since I do have a sub, and $$ aren't unlimitted, what do you all think???
Thanks
