We could do that, but it seems his stuff is just a pot-in-a-
box with a Noble attenuator. If you go that route, I would
look at the Music Reference PiB which uses one of the most
expensive attenuators ever made by Noble, the one used in the
ARC SP6. However, we are trying to identify the best volume
control, so some system context and comparative info would be
useful. I believe that most passives, in the right system,
including Richard Lee, will sound very good compared to most,
not all, active linestages, but if you are looking for the
best, I don't think you can come to any conclusions till you
have heard the Lightspeed Attenuator, for my money, it is the
one to beat - including any resistor, TVC or AVC on the
market.
