Looking for some advice. I'm going down the path of adding a 2ch integrated to my current AVR driven HT/music setup to do dedicated music duties. Setup will be as follows: Marantz NR1602 (until I pickup another avr to get rid of the stupid DD+ decoding issue) NAD C368 (waiting for it to arrive) Revel M16 as mains Focal CC800V as the centre SVS SB1000 (non-pro) So all my AV sources will run into the AVR, which will drive the centre directly and send a pre-out signal to the HT bypass input of the NAD, which will drive the Revels. Music sources will be fed directly to the NAD and the avr won't even be on for that playback. My question is about the sub: I'd like to be able to use the sub for both AV and 2ch listening, and my preference for AV playback is to drive it from the dedicated sub output on the AVR, as from my testing so far with the Hegel amp I currently have, that produces better results than just feeding the sub from the 2ch's preouts with the AVR seeing the integrated as full range mains. My initial thought is to do this: sub output on AVR to low level input on sub preouts from NAD into 2>1 RCA cable and into the other half of the low level sub input sub LPF and levels tuned to blend with the mains for 2ch listening (I expect to be around ~60-80Hz) I know that will work fine for 2ch, because it's how it needs to be setup regardless. But what I'm hoping will also work is that when I setup the AVR using audyssey, I can set it's internal crossover to match what I have set on the sub itself and it will send all the LFE plus the low end of the other channels to the sub via the direct cable it has. It'll then send the remainder of the crossed signal to the NAD which will drive both the mains and the sub, but that extra signal to the sub should be filtered by the LPF at the sub, so really the sub is only being driven by the signal coming direct from the AVR. I'm thinking though that I might end up with a spike just below the crossover freq, since that attenuated portion will be coming from the NAD and get past the LPF on the sub, but I'm hoping that the (admittedly crappy version) of Audyssey on the AVR will be able to largely account for this in its DSP. Thoughts? Alternative options include using the NAD's built in HPF instead of the dual setup, but it seems to be fixed at 150hz which I think is going to be too high. I could also get an RCA switcher I guess and so long as it has an IR remote I can get it to switch the sub intput as part of my Harmony activities, but I'm not sure how reliable they are.
