Duo-Tech Cable Enhancer - a unique and nice little box to help burn in
interconnects and speaker cable. The unit has RCA jacks, with adapters for
speaker cables (via binding posts). Hook up your wire in the appropriate
direction, turn the unit on, and leave it. A constant signal is sent thru,
helping burn in cables MUCH quicker and quieter than using the stereo. I
have used this quite a lot, mostly for interconnects. It does work, though
there is still some improvement once the cables are in the system. This has
saved me a ton of time over the years. The Unit is like new in the box with
all adaptors and instructions. Was $199.00 new. $75.00 or b/o
