Looking to upgrade


Hello, I'm looking to upgrade my home theater system and was trying to figure out where to start. I was thinking starting with an old Lexicon DC processor and 5 channel amp. I don't want to spend an arm and a leg, but want to improve the overall sound over my setup which includes:

Original KEF 105's mains
KEF C100 center channel
NHT VT-3 surrounds
SVS PB12-ISD subwoofer
Marantz SR-18 receiver
PS3 for Blueray/DVD

Any suggestions would be appreciated.

Thank you for you graceful response to my post. I'm afraid our beliefs are irreconcilable.

It is interesting that you say you used to hold the sort of views that I do, but now have moved on to your current position. I am just the opposite - I used to hold your views, quite tenaciously, until listening experience forced me to relinquish them.

There is nothing that is mythical about the differences I and so many others hear. Likewise, there is apparently nothing convincing to you in what you hear. I suppose the good news for you is that you save money on electronics. The good news for me is that I am able to hear more music with better gear, music that stirs my soul.

Advice from someone who has been there... upgrade your amplification . It will give you the biggest bang for the buck and a noticable improvement . Buy used and get seperates . Receivers just don't have the power to get the most out of decent speakers . If you are on a budget , start with a good 5 channel amp and use your receiver as the processor .

Good luck .
