I would be interested in this filter. Mine has this pretty bad as well (2004). I have the audiophile system and if you turn on the radio you can hear the wine if the radio is only like 1 or two notches up, and the whine matches the rev. I had this REALLY bad on my summer vacation. I had my laptop as my 80GB MP3 player, plugged into the read DVD AUX port, and the laptop was on an inverter (Pure Sine Wave 500 watt inverter). The noise wasn't there if it wasn't plugged in, but it sure was noticeable, even at mid volumes, when plugged in. I thought I wouldn't have that issue since I bought a pure sine wave inverter.
