Yes, but in this thread earlier it said that the frequency's below 100hz would be lost on a 5.0 disc under such a set-up. Only that bass intended for the LFE (which in the case of 5.0 is nothing) would be present. So you are saying that this has been fixed since the 1400 originally came out?
Actually I just realized that I had a Frank Zappa DVD-Audio disc that is also 5.0. It has a DTS stream which I could try this on.
