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 ;)

I do get the potential issue being the source (material or player). Right now I'm using a PS3 through my AVR - Yamaha RXA3010. An Oppo 103 is on the shopping list. I know (now) that Yamaha is notoriously bright, so that certainly could be the issue, but it is relatively new, and the processor for movies, so I'm loathe to replace it. I'll have to verify which i/c's are going to the Odyssey - I was using AQ, but they are made in such a way that the terminals won't spread far enough part to connect to the amp, so I switched them with the ones I'm using on the sub, and have to see what those are. Speaker wires are old Monster cable from when I got the speakers. Can't remember which ones though. All I can say is that the actual wires are about 16 gauge, wrapped around a central conductor, then insulated and the plus+minus are then wrapped again. I use bare wire, and trimmed back for 'new' wire connections.
Some of the material I notice the harshness on is off Pandora, (but by no means all), which is using the ARC on the HDMI.

There is an 'itch' for new speakers, emotionally based as so much of this is, however the $$ isn't really there...the wife says it's her turn, and has a long list ;) (and to be fair, she's right).

It does bring up the next point though...Given that perfection is a moving target that can never be acheived, at some point each of us has to say 'enough's enough' and be content. Fine tuning to get the most out of what we have is also important, and the synergy of course - $5K total can sound better than $50K worth of equipment - Having said that...I think it makes sense to me to have an eye on where I may go with speakers in the future to prevent wasting money in the short term. Also, one of the items on wifey's list is taking out half the back wall behind the listening position, making it open to the kitchen. The room is currently 19 long, but opening up that wall will make it 36. To picture the layout of the 'new' back wall, it would be open except for a false header full width, down 1' from the ceiling, and from left to right, a half wall 3 1/2' high, 7' wide, leaving 5' open. the room itself will go from carpet to wood floors with area rugs. (so brighter yet). So, the environment for the speakers will change their sound as well.

Should I wait til all that's done and see how big the problem is then? Perhaps (unlikely) the room qualities will ameliorate the problem, or conversely (and most likley, given Murphy's position on my back most days) make the problem too great to be 'solved' with cables-I/C's. Or is the change in the room not likely to be so great as to render changes I make now in cables-I/C's pointless? How do I determine a realistic budget for 20 year old $1600 speakers, a $2K AVR bought cheap, and a $1500 amp bought used for less. I know I could easily spend that sum on one pair of interconnects and speaker wires.

Thanks!!
English210, Don't try to use common sense, it just confuses us. I might add that your Rationalization skills will need to improve if you are going to get those $$ interconnects.

I would go for better wire if you can pull that off, and keep your wife happy. It can always be resold. I will let other experts help you with wire recommendations, but I used Reality Speaker Cable when my system was bright, and Audioquest Type8 was really warm to me. Also Anti- cables worked well on one system and were terrible on another. The cable abyss.
@ english210,Do not be suprised if the bigger room improves your sound,I am banking on that it will!,you do need better cables!,take your time!,we all buy a little at a time,I am not rich!,I have been building my main system for a year now,and still building it!cheers!
Ah--your question of choosing appropriate interconnects and cables...
My future son in law who led us back into vinyl after 10 years away, is an avid audiophile. His rule of thumb-- speaker wires should be 15 -20% of the cost of your speakers. If you double the cost of your speakers to minimally account for inflation, you might be looking at $600-800 for speaker wires. Interconnects--his rule of thumb is buy a good name brand used set for $200 or so. That gets you about 80-90% of audiophile wires. You can but cheaper for interconnects that feed your rear speakers.
He likes kimbers, nordost, MIT as his go to interconnects. If you want to tame harsh highs, Silnote interconnects are designed to do that, and have sweet mids. If you stay with solid state, choose copper wires. Do not buy $100 silver wires--your ears will bleed!!
We bought some Tara interconnects for our vinyl setup--superb!!! They are VERY neutral and will show you if there are flaws in your setup. So don't buy them if you don't love your amp and speakers.
We own Tara's, MIT, AQ, and silnotes. I have some monsters in my home theater setup. Just move them away from your front speakers.
Wow, with all that change going on, I think I would concentrate on getting your Oppo and 5 pr of decent interconnects to hook up proper analog sound from the Oppo to your amp. I had a flagship for its day Yamaha rxv1 that still plays my center and rear speakers in my set up. Your Yamaha amp should suffice for home theater. The ps3 is great for movies and Internet connection, and doesn't have to be replaced by the Oppo--depends on you! We use a ps3 for our mid-Fi home theater set up and are fine with it. But the Oppo should kick its butt on music playback--superior drivers all the way around. We reserve our Oppo for the separate audiophile setup/music playback.i
Once your Oppo is in place, your "source" 2.1 playback will be about as good as you can get. If there is still harshness, then a 2.1 amp would be my next purchase. Because speaker wires work in synergy with amps and speakers, I would upgrade them after your amp or speaker purchase. If you find your playback greatly improved with the Oppo and are almost there, then keep your amps and speakers and grab some better quality speaker wires for your front two or three (center) speakers. If harshness remains, save for a decent 2.1 amp.
I am no expert. But that is what I would do. Start with the source and work outward.
Btw, I use an hdmi cable from my Oppo straight to my tv for picture for my music DVDs. I use analog cables from the Oppo to my Yamaha and from the Yamaha thru my kw500 for fronts. Sounds heavenly.
When we bought our Yamaha, we bought some laid-back Vienna Acoustic speakers to tame any harshness. Worked pretty well. But the tube amp made them reallllllly shine. I have seen vienna acoustic mozarts go for crazy cheap prices on the Gon. If you get viennas, I can vouch that MITs are a crazy good synergy. My VA Beethovens do well. Someday I will upgrade from there, but for $500 for used MIT 750s I get $2k in performance. I am not ready to spend the $3k to better them yet.
Btw, for our rear speakers in our midfi TV room, we still use the 16 gauge monsters!! But if you find some better speaker wires super cheap, you can always grab them for your front right and left. Buy a brand name used that you know you can turn around and sell later. It will improve your sound. Don't buy cheap silver interconnects or speaker wire with the Yamaha. Your ears will bleed!!!
My two cents!
