can a new amp amp tame my speakers?

Just spent some time listening to what I've been planning to upgrade to for main speakers. PSB Synchronys. The Imagine T2's are close, but slightly veiled in comparison. My current, but old, Infinity Kappa 7's really don't give much away to the PSB's. My amp is an old Yamaha MX2, 125wpc, and I've heard them described as bright or harsh, and that's the only complaint I really have with the sound now. Can a well-chosen amp tame the highs on the Kappa'a, which use a ribbon-style tweeter? Or is the 'taming' I seek only going to happen with a speaker upgrade. I honestly don't mind upgrading the speakers, and fully expected to, but after today's auditioning, I'm wondering if I'm going to get that much benefit from that level of investment. $3500+ is a healthy chunk of coin for benefits of slimmer profile and tamed highs. In terms of imaging, weight, and bass, the Kappa's are equal, imo. The system is also the theater, but the avr can power the surrounds, so an amp upgrade could be 2 channel. A power boost is a must too, as the current 125wpc isn't enough for when wifey's not home and the volume gets wound up ;)

English - In absolute terms, no, it doesn't mean much. Coupled with your speakers' efficiency rating and room size, it can mean a lot. IIRC, Yamaha AVRs used to be widely criticized for not having enough output. Especially when tested by mags like Home Theater, the power output would usually fall to well below the advertised output when more than two channels were driven.

I think the best way for you to procede is to either borrow a more powerful amp from a friend or dealer to try out, or purchase an amp from a direct seller or dealer with a good return policy (watch out for "restocking" fees). Then you will see quickly if a beefier amp gets you the results you seek.

If not, report back, and we'll take it from there.

Bondmanp, ok, so I'll fill in the blanks: The problem I'm having is in 2-channel mode, so the avr's only sending signal through the preouts, the surround speakers it is also powering aren't in the equation. The speakers are notoriously tricky, Infiniity Kappa 7's (but they're far easier to drive than the 8's or 9's big brothers) with a guestimate of efficiency @ 87ish. The room is 12X19X8. I had thought of just trying an Emo amp, but then I read they can be bright anyway, and that's the last thing I want. From the feedback here, I'm 'aiming' for a Parasound, Classe (read elsewhere they are laid back), or Wyred. Emo has the best return policy if it didn't do the job I need, but if they're bright-ish anyway, what would it tell me?

I'm of the opinion that one should purchase an amp that best allows the speakers to do all that they're capable of, not fix the speakers.

I agree, but if you read my earlier posts, you'll see that the sound is great until volumes get elevated, THEN it gets harsh/bright and objectional. Until then, they sound great. My question originally was perhaps phrased badly, and it was written badly badly, but the intent is clear enough. I certainly wouldn't want an amp that tends towards brightness, based on the problem I've having. Most brands claim and aim for neutrality, but the reality seems to be that there is a tendency, or favor, towards one range or another. Some emphasise bass, some mids some highs. At least until you get to the upper price ranges I can't reach. So, here I am...

I did read your earlier posts, and somehow missed the part of high volume causing problems with the highs. I've just reread it, and sure enough its there. Another amp, perhaps with more power might help, then again it might not. Are the added subs self powered?
