The Moscode 401HR improves substantially with a good active preamp, IMO. I
initially heard the 401HR in the Moscode demo room at the LA Home
Entertainment Show in 2006 (I think it was 2006...). George was using the
Placette passive preamp.
I thought it sounded very good, but I thought it sounded even better...more
musical, robust and lifelike...with a Lamm LL2 Deluxe preamp.
While I can only speculate, I suspect George selected a passive preamp to
eliminate one variable that could affect the system's sound. By using the
passive preamp, listeners could be more certain that they were hearing the amp
as uncolored as possible.
