New Speakers or Dedicated Amp?
Here's my current 5.2 setup:
Polk CSiA6 center
2x Polk RTi10s towers
2x Polk FXi A4 surrounds
2x HSU VTF-3 MK5 subs
I'm trying to coax some "better" sound out of my setup, both for movies and music. If I had to isolate a weak link in my system, I'd be forced to point to the RTI10s. Don't get me wrong, they are wonderful, reliable speakers, particularly for the price I paid many years ago, but I would like to get some more out of them if possible, or look into upgrading. To add some detail, they are fairly clean, always play with zero discernible distortion, and they can get quite loud. On the other hand, they can sound a little shrill and thin at times, and on occasion they have a "distant" quality...like they're playing through a thin barrier of some kind. I know that's a rather vague and probably unhelpful description, but it's difficult to translate into text.
Anyway, at 89dB they aren't the most sensitive speakers around and the Denon is not exactly a beast in terms of power output. Would I be well served by something like a Monolith 3X? Would this "open up" the speakers at all, particularly at high volumes? Or should I look into different towers completely? My concern with changing speakers is that I would then be faced with the possibility of needing a matching center, and I'm really not looking to stretch my budget that much. Whatever I do I'd like to stay under $1500 total.
Also, with the two subs taking up LFE duties, full range towers maybe aren't necessary to begin with. Everything is currently crossed over at 80Hz.
Primary uses are movies (played at or near reference) with a fair amount of 2.2 channel music thrown in.
For reference, the best sounding consumer speakers I've personally heard were 800 series B&Ws - obviously those are dramatically beyond my budget, but that's the overall style of sound I'm after...somewhat warm, yet crisp, very detailed and impactful.
Thanks in advance for any suggestions.
