It looks to use the same caps as the RX-A860 which was measured by Gene. It`s bit shame if you compare to old days when there was less features, but the internal components were better. But with all these fees they have to pay Dolby, DTS and god knows who these days it´s quite understandable that the compromises have to be done somehow to keep same price. At least on the budget models. \n\nRx-A30x0 has 18,000uF caps. Denon X6x00H 15,000uF i think @PENG mentioned. Just general information, not to directly compare 400-600$ product to these expensive ones.. \n\n\n\nThe power supply is a bit smaller than I've come to expect in AV receivers in this price class. As comparison, the power supply in my friend's $400 Yamaha RX-V659 AV receiver that just lost a battle against a lightning storm is a bit bigger with a larger IE core transformer and more generous capacitor bank (71V 12,000uF Caps x 2) compared to the much more expensive RX-A860 (71V 8,200uF Caps x 2).
