Before I moved I had the McCormack TLC-1DLX connected to a Pair of DNA-1DLX Golds for vertically bi-amping which yielded great results, after I moved and had my system setup I tried the McCormack Micro Line Drive that was upgraded to Gold by SMC audio. The results were so outstanding I have yet to put the TLC-1 back in the system. I'm talking this is what transparency is all about, this pre-amp is not there at all with deeper blacker backgrounds than I thought possible. One of the good things about the Micro Line Drive is it has both Passive and Active output, so if you don't like one you can switch to the other. Also the active side has an adjustable output. As a side note I only had the TKD Conductive Plastic Volume Control installed not the more expensive TKD Stepped Attenuator and have nothing but regrets for not having the better one installed. The TLC will be going in for the Platinum upgrade real soon.
