The upgrade bug is back again. Not sure if I will really be able to better what I have in this beast :rolleyes: I have had this amp for over a year and very happy with its performance driving a Paradigm 5.1 reference set (studio 100 V.3s, cc 570, ADP 470s). This is housed in HT entertainment center, non pet and non smoking environment. I have the original box and manual. The amp is in excellent condition. I would not want to ship this 115 Lbs amp. Would like to sell it locally in Dallas. Asking for $1650. Here is the link to a PDF file for specs. Also couple of links for reviews. http://www.sherbourn.com/PDF/7_2100/7_2100_Features.pdf http://www.audioholics.com/productreviews/avhardware/SherbournPT700072100.html http://audioholics.audioreview.com/cat/amplification/amplifiers/Sherbourn/PRD_302718_1583crx.aspx my contact: sumit.ralli@sbcglobal.net
