I bought this years ago for my home theater. Soon after I moved and dismantled my HT and the BFD sat in storage for probably 8 years or so.Now I am in my new home and have my HT set up again. I do not have the same sonic issues that caused me to purchase this in the first place. This unit is in its original packaging and has never been hook up. I opened it recently just to be sure that it powered up. $60 shipped to the lower 48 Thanks for looking at my ad.
