Dan-
Thanks for the heads-up. What is your opinion of the quality of the stereo in the portable intercoms? Is stereo capability for music worth the added cost, or should I stick to mono?
No reason to pay extra for something that might be of marginal quality, sound-wise.
Dennis,
I am assuming you have stereo headsets (otherwise you will have to operate mono on your intercom). Quite frankly, I had a PM6000B panel mount and Lightspeed 20XL's. The difference between stereo (just using the CD and headset adapter) and mono (through the intercom...it's not stereo) with a portable CD player to me was only marginally a benefit. Add to that the high noise environment of the cockpit and mono music is probably not a huge setback.
I hate to admit that since I am very into audio (have my own little basement studio) and really like quality sound. The Lightspeeds (especially the QFR solo's I have for the back seats) do a very nice job of sound reproduction, but I do not feel that the stereo/mono difference is great enough to be overly concerned about.
