Reviews: The 640R’s smooth, substantial fascia is mercifully free of extraneous controls, as is the beautifully tactile remote handset – only the thin, brittle-feeling volume control and the BBC Micro-style set-up menus strike a low-rent note...The manual set-up is simple enough (though it’s a struggle to get the subwoofer to meet the speakers at a common volume level), and the fascia display, while a bit on the ‘big print for the optically impaired’ side, is at least legible from a distance...Thanks to the 640R’s HDMI-switching, video connections to a display can be routed through the receiver...Dialogue is distinct, the bottom end – while fractionally fuzzy – hits good and hard, and effects are steered rapidly...
Retrevo's Recommendation: Older product, look for current models
