Don't know if this will sound too opportunistic, but I was just about to list a pair of Audio Alchemy DLC preamps that served the same purpose in my system. The reason for two preamps is that if you are running a subwoofer, like I am, I wanted to be able to use the subwoofer for my two channel listening, not just home theater. What I did was run the output of the DAC to input one of the first DLC, and the front left and right output of my processor into input two. Since the DLC has dual outputs, I ran one set of outputs to my power amp, and the second set into input one on the second DLC. I then connected the subwoofer output from the processor to input two of the second DLC, and the output of the second DLC to my subwoofer. I know this sounds complicated, but once you get it all set up, it makes it possible to switch from your two channel setup to your home theater setup at the push of one button. The trick is to program the second DLC to unity gain, that way when you use the remote to switch from input one to input two, the subwoofer sees the appropriate signal. When listening to two channel, the processor is completely out of the circuit path, while in home theater, the only degradation is the additional run through the second DLC on the way to the amp. Whether you decide to go this route or not, I'd be happy to help you out either way. Just send me an e-mail at screedchan@yahoo.com
