I've had a pair of RF-7's for the last 1-1/2 years or so and have been very pleased with them. I've been running a 2-channel setup with a Parasound P3 preamp and A23 amplifier and Denon 3910 DVD player. Both speakers are biwired. Recently, the left speaker has dropped significantly in SPL compared to the right speaker. When I use AVIA and a SPL meter, it measures about 10 decibels lower than the other. I've swapped all components and cables to make sure it's the left speaker, and sure enough, it is. I bought these from Good Guys, which obviously went out of businesss several months ago. According to their website, it says all service plans and warranties will be honored through the product manufacturer only, so I'll have to talk to Klipsch. It says to refer to the product manual for more information. My question is, I spent hundreds of dollars on extended service plans for all of my speakers (in addition to my two RF - 7's, I have five RB - 75's that I'm planning to use in my basement home theater in the coming months). Does this mean I'm just out of luck with Good Guys, and have to send it directly to Klipsch for repair? How long does something like this take to get the speaker back. I may just have to run a pair of RB - 75's in the meantime. I'm obviously going to contact Klipsch customer service on Monday morning, but here it is, about 1:30 am on a Friday night and I'm upset. Does a consumer have any recourse whatsoever in a situation like this where extended service warranties cannot be honored by a retailer because they've gone out of business, even when that same consumer spent upwards of $500 on those plans? Anyone have any advice? Any and all help is much appreciated.

Wow! Thank you to all who are responding. I truly appreciate the input and constantly find myself eager to learn more and more. This seems to be the right place... I find it fascinating that XLR cables can actually introduce noise into the system. I will switch them out and use RCA cables to see if this is indeed the problem. Thanks again.

Hello all. I was hoping someone could clarify if there are actual differences between playing a CD on a dedicated CD player or DVD player. If so, why? It would seem to me that since both are digital players, the differences in audio output would be minimal (if any), but I've heard that because CD's use redbook audio, they can sound harsh if played on a DVD player, but I cannot substantiate this. Can anyone provide an explanation? I have a 2 channel setup and would like to know if I should eliminate my DVD player as the source component and replace it with a dedicated CD player. Would this make an appreciable difference in sound quality with CD's? I'm running RF-7's with a Parasound A23 Amp / P3 Preamp combo, along with a Toshiba SD5700 DVD player. Thank you.

I've been looking for quality 2 channel separates for some time now, and finally found a discounted Parasound Halo A23 Amplifier and P3 Preampifier combo at Good Guys this last weekend. Apparently, they're discontinuing the Parasound products, so they've been on clearance for awhile but I got lucky and found these units after calling every store in Washington State. Anyway, I wondered if anyone on the forum had any experience with these 2 units? If so, how do they mate with RF-7's, which is what I'm running for my current setup. I'm still new to separates, and am trying to critically listen to see if it was worth it. I know I got a good deal, and they are certainly an upgrade over my Yamaha RXV 1200, which I was running in stereo, but is this a decent mid-level 2 channel configuration? I'm also using a XLR cables from the preamp to the amp, but not from the source component to preamp, as my Toshiba SD5700 does not have balanced outputs. Also, one thing I've noticed is that there is a faint "hiss" coming from both of the horns on the RF-7's with the Parasound combo hooked up, but it's not present when I switch back to the Yamaha. I've tried all the recommended fixes in the troubleshooting section of the Parasound manual, including activating the "ground lift" switch on the back of the A 23, but no luck so far in eliminating the hiss. It's not very loud or noticeable, but it's there nonetheless and annoys me. Thanks in advance for any help. I've been lurking around these forums for awhile now, but this is my first post...
