As my Kenwood VR-2090 has gotten older, it has become more sensitive to heat. The symptom displays itself as a clicking in the speakers when the IR remote is used. I have relieved the problem somewhat by moving the center and rears to an external amp (unfortunately - no pre-outs for L and R). I am looking for a solution to help keep this receiver cool. The only thing I have found are these equipment coolers at Smarthome. The price seems a bit steep. Any opinon on these? Is there another solution I am missing?
