can a new amp amp tame my speakers?

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

It sounds like you want new speakers. Don't expect any of us to stop you. ;)

If anyone is going to be of help, we need to know what source, and cabling you are using. Your current problem can possibly be solved with a preamp, cabling, or source, but maybe you need new speakers to start with???

Sometimes ones dissatisfaction is in the recordings themselves and not necessarily with the playback system.

@ English210,The problem you described can be fixed for sure with cables!thats were I would start,please do not go chaseing the cat by the tail by mixing different cables,I have friends on the gon that do that,seems they are never satiesfied with their sound!,I do not believe you need other speakers,I agree with acman3 with what he said,but with the exception of keeping the speakers you have,It appears on the most part that the aquaired amp you just got is working out good for you,excellent!,cables useally become an issue when we change a componet,the synergy has to be matched,their are plenty of cables that will fix the ribbons sound that you have,If you want a basis for recommendations for cables,and your desired pricepoint,let me know,cheers!

English 210, I jumped into the audiophile fray a couple of years ago and have learned a lot. As my ear has improved, I have learned a good deal about synergy of systems, etc!
Before spending more on speakers and amps, you might want to check on what you are playing your CDs in. We upgraded to an Oppo 95 last year from a Yamaha DVD player. I was astounded by the huge improvement in smoothness and imaging. My kids $300 bluray player sounded harsher and thinner by comparison.
Also, trying different interconnects made big differences in my speakers' perceived character. I tried very high quality Audioquest silvers that made my fast, but musical vienna acoustic speakers sound harsh on the top end. Low quality copper wires collapsed the soundstage and dulled both bass and treble extension. Everything affects the output!
Speaker wire upgrades--I stepped up from $150 monster cables to MITs. I bought OLD generation mIT 750 series2 with cvt speaker wires and had them professionally reterminated so that age and oxidation didn't interfere with my sound. MITs were a bit darker and more transparent and linear than the monsters were. They are reputed to roll off highs a bit, though I have not seen any issues with the sound I am hearing from my setup. That roll off however "could" help with your harsh highs issue.
I am not familiar with either your speakers or your new amp, so I cannot speak to their characters. However, synergy is an issue. If the amp is one you like, then take it with you if speaker upgrades are your chosen path.
When we first shopped for our system, we chose an amp we liked, then tried speakers with it till we found a set that sounded right with vocals, tympani and horns. Few speakers did justice to all three, but fewer still did a great job with vocals.
Good luck!! Have fun with the process!!!!
