I have one used but in like new mint condition Rives PARC 2 channel 3 band (per channel) parametric equalizer including power cord, manual, test CD and original box. Pristine without a mark on it and works perfectly. This unit was completely transparent in my system as reported by others and fixed a major bass problem I was having. I have since moved to a new house and room with no bass problems so do not need this fine unit anymore. I tried bass traps in the corners and moving speakers around but nothing really helped until I got this unit; if you have some bad room dimensions as I did you really have to nip it in the bud at the source instead of trying to add patches to the problem. This unit not only works like a charm but looks very upscale as well with nice craftsmanship and high quality throughout; also has won awards with excellent reviews found at rivesaudio.com. Current list price is $4,000 so save and get this like new one for less than half price. UPS shipping $75 includes full insurance; no shipping to Alaska/Hawaii, US Protectorates, APO/FPO, PO Box. Add3% if paying with Paypal. If in DFW TX area you can pickup and save shipping/Paypal fees.
I hope you enjoy this unit as much as I did. Thank you for looking and let me know if you have any questions.
