I have the SH and wish I would have gone with the SM or SL. I don't like it run through the mm stage of my VAC. The loading isn't right and the 40db gain is a hair light. I use the Phonomena pre which is very adjustable, with 44db gain and 1000 ohms loading. It sounds good but I have a suspicion it would sound better with the lower output fed into the VAC mc input.
