The Audio Research SDP1 operates as a matrix unit in the analog mode. Ordinarily, you would take a preamp output and connect it to the SDP input. I used the second output of the Qol and put it into the input of the SDP. I am not using the front channel outputs of the SDP, but taking the Output 1 of the Qol straight to the basic amp. In other words, I am not taking the front output from the SDA1, just the rear channels.
This setup produces a believable illusion, and all the levels are controlled by the main preamp.
As an aside, I would say that I have been entering into all kinds of hi fi discussions on the net, and this is the first one where all participants are helping each other with a new, untried product. I am sure that the usual prejudices of orthodoxy will eventually creep in. I have already gotten some flack from the purists at the Sound Lab Owner's Group, where I first brought up the topic of Qol.
