If you look at AmirM's review - although the wording is "clips" it maintain SINAD above 75db at 2V+
The tech review is not clear as to how much more V it can put out beyond that while maintaining acceptable SINAD (ie at what point does it truly "clip" and SINAD drop off dramatically - at 75db the SINAD is till within the acceptable audibility range!)
Denon AVR-X3800H Review
This is a review and detailed measurements of the Denon AVR-X3800H 9.4 Home Theater Audio/Video Receiver. It was kindly drop shipped to me by a member and costs US $1,699. Not much to say about the look of the unit as it is pretty much similar/same as last generations. Here is the back panel...www.audiosciencereview.com
