I have just sold my Yamaha DSP AX1 because I'd like to get into the newer HD audio formats. The Yamaha was built like a tank and what I'd like to know is where do I have to start to find an amp that will match it in plain DD/DTS stakes (I'd hate to buy a newer amp that sounds great with HD audio but not as good as theYammy in plain vanilla DD/DTS mode)? Is the Onkyo 875/ Denon 3803 / Yamaha RXV 1800 a good place to start?
