I have the 1070 and use it in the bypass analog mode (toggle all the way up). I use the pre-outs for the front and center speakers to NAD C370 and NAD C270 amps. While the 1070 in bypass analog mode sounds pretty good for two channel listening and allows me to use a sub-woofer, I have found that it is does not sound quite as good as my 2 channel integrated amplifier (NAD C370). I also use a unity gain set-up with the NAD370 so that I can use it for two channel as well as to power my front speakers when using multi-channel. I have the Denon 3910 and I usually let it do the decoding as opposed to the 1070.
