This is an absolute monster. If you are looking for a separate two channel amp for your towers, this may be it. This is the one (I think Clint or DVV) that was mentioned putting out enourmous power for long periods of time. HK Citation - older, but one of the best amps ever for home audio. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=71546&item=5779084925&rd=1&ssPageName=WDVW
