Summary: Not impressed by the QC on this product. I bought it because I have had great luck with Yamaha products in the past, but this one did not tow the mark. The unit blew out without tripping the built in circuit breaker, so I could not do anything but watch it go.
Summary: Unfortunately I hooked everything up in my tight/cramp stereo cabinet to find out it was DOA. Really wished I would have plugged it in as soon as I unpacked it. Fortunately the seller took care of things quickly.
Summary: One of the main reasons I bought this unit was the subwoofer out. It turns out the unit has less control over the subwoofer than my other Yamaha and Sony amplifiers with two sets of speaker outputs and controls. (Much less bass as a result.
Summary: Nice overall, except it doesn't work with TivoHD. When switching channels or powering up, the unit creates a loud, high pitched squealing sound for about 1 second. It's impossible to ignore. It happens on both the HDMI input and running in Optical.
