http://www.behringer.com/02_products...T1951&lang=eng I played around with this for 2 uses: a) parametric EQ for my main front L & R speakers. (Because it's analog, won't degrade the signal the way a digital eq would.) b) Adds an adjustable amount of tube sound to the signal. Original Manufacturers Suggested Retail Price $189 My price: $100 The unit is in like new condition (I've had it less than 6 months), and come with the manual, warranty registration card, and original box. Cashier’s check, money order, and personal check (must clear 1st) accepted. Paypal too. My ebay id is kcb-5. Check it out: NO NEGATIVE FEEDBACK. Ever. Zip, zilch, zero negative comments from anyone who has dealt with me. I'm not a dealer out to make a buck. Just an audio/videophile who likes to try different things.
