If you're interested there is a McCormack TLC-1 with the Rev A upgrades done to it. The TLC has a buffered output that is second to none and a passive output. Plus if you want to improve upon its performance you have the help of the designer here on this site or at SMc Audio. The price being asked would cover the cost of having one upgraded. I've enjoyed mine so much I had mine upgraded to the Signature Edition that includes the power supply built for the VRE-1c and balanced outputs. Anyway just a suggestion.
