Audio Systems: Stereo receiver channel shorting, denon receiver, power reserves

Question
I have a Denon receiver I bought about 8 years ago (40 W per channel) and lately the left channel has been partially or totally dropping out or suffering from distortion. I've found that applying pressure to the top of the casing on the right front part corrects the problem, at least temporarily. Is this due to a short or a loose wire or connection, and is it worth trying to fix?  

Answer
Dear David,

Hmm. Yes, if external pressure restores the sound, it would seem that something's out of place which cwuld probably be fairly easy to fix. The cost should be minimal, perhaps an hour's labor ($125-150) plus parts. Most repair facilities will charge you a half hour's labor for a diagnostic and a total repair cost--to which the initial fee is credited, otherwise generally not refundable.

However, the "worth" issue is problematic. First, 40 wpc isn't that much. It will drive smaller speakers and very, very efficient larger speakers, but it lacks the power reserves to get to dynamic musical peaks without pooping out. I have no idea what kind of music you listen to (or what kind of speakers you have and the size of your listening venue--both additional factors in the power equation), but this should be a consideration if you enjoy orchestral music at realistic volume levels.

You can replace it with an up to date 2-channel model with better power (I recommend 65+ wpc) from a good maker (Onkyo, Denon, Sony ES, Outlaw, Rotel) will run you around US$300. A newer model will also be more reliable in the long run.

This is not an easy decision. I'd suggest surveying the newer models that might interest you, both for features and price. Then, if fixing the Denon is still an option, take it to a repair facility for the estimate.

Good luck. And thanks for choosing allexperts.com!
