Know anything about the BSG Technologies QOL?

My advice: don't waste the output on the sub, since directionality is so little in low frequencies. I am running my sub directly out of the preamp. I think that you are correct is stating that the Qol should have been a multichannel device. Remember, the volume level on the rear channels will have to be bigger for balance. You will see that the info coming out of the surround channels is quite different and much more realistic.

Preale, I agree about subs. I tried my JL-113s both ways, but preferred subs driven from preamp. This weekend I will test supreme fuse and give feedback to group.

Preale, With only an analog input on the Qol, how are you driving the rear channels?

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.

Preale: Like someone said earlier.. "stereo is also just an effect". That's so true, you have 2 speakers trying to create the illusion of the room. So now the QOL is also an effect, and apparently doing a nice job by adding to the 2 channel setup. I would love to hear it, but I wouldn't order one for the 30 day trial as I know it would go back because I can't afford it. I'm going to AXPONA in Jacksonville, FL in March and I hope to hear one there.
