Another find from the closet. This is the stereo R203 feedback stabilizer that sold for $109. It worked really great with several CD/DVD players, including the Toshiba 3980, Oppo 980, Denon 2910 and Denon 3910 but as I exclusively use an external dac with my Oppo now, I don't need this anymore.
$40 shipped in lower 48 and no paypal fee.
Yes, the vendor's ads are a little off the deep end but this thing really did work quite well on the players I mentioned.
Thanks for looking,
Jim
