I was wondering if anyone has noticed a change in the sound since the recent upgrades over the past 6 months or so? It seems the sound I am getting has to much bass or something. I have a Philips plasma that has OEM speakers and was just fine until about 6 months ago. Most channels are OK and some have a distinct irritating rasp or ? I just use regular speaker cabling from the reciever to the monitor. I am not sure if I went to a HT system if this would clear it up since I would be able to adjust sound a lot better. The adjustments through the Philips isn't getting rid of the problem. Anyone notice a change? Thanks
