As I narrow down my avr choice for 5-channel HT and 2 channels for a second room, I’m considering a hybrid route. I was thinking of buying an HK 520 for $500 or so and teaming it up with a Nad c270 for about $500. I’d use the Nad to power the front Dahlquist QX10s I plan to buy to handle their 4 ohm load, and ideally get the Nad sound I love in 2-channel playback. I like the sound of Nad over any other receiver I’ve heard. The HK would power the center, surround rears and main pair of inwall speakers in the second room and provide all the processing. And it doesn’t have a fan, like the 525. Alternatively, I could buy the HK Pa 2000 amp (2 x 110 bridged) instead of the Nad and save $200. Has anyone here tried this sort of hybrid route with great success? I might just go with one AVR, but I wonder if I will get all the sound I could out of the four-way DX10 tower.
