Hello, does anybody have opinions on the SB Platinum "idrive" drive bay thingamajiggy. I was wondering if i should plug my mackie into the front unit with a 1/4" jack or should i plug directly into the soundcard line in on the actual soundcard? it seems that pluging into the front jack would make for a longer signal path and also that line in volume nob sounds like it introduces a lot of noise. thanks...
