I can't disagree with anything Pipetman said, but could add that I'm using a DIY passive with OTL amps with no problems. Placette looks very good to me but if you're a DIY type at all, you can make a world-class passive using Shallco switches, Holco resisters (Michael Percy Audio has kits) and good input and output connectors, RCA or (better) XLR, for about 1/3 of a Placette's price. But will it be as detailed and transparent as a CD player with a good digital volume control? In my experience, with an Accuphase DP-75 going into my OTL power amps, definitely not. There's little in a good passive to degrade the signal--but in a refined system even a little degradation can be clearly heard. Bu the way, there's a recent post on passives you might want to look at.
Placette pre amp
I don't have a pre-amp yet and I'm not sure if I should get one. I am waiting to decide whether to buy a cd player with a volume control or to get a passive pre-amp. What would be the difference in sound? I have tube amps (Legend Audio Design) and love the sound of them, but their pre-amp doesn't have a volume remote, which I really want. If I get a passive preamp or cd player with a volume control will I lose the sound of the Legends? I know there has been a lot of discussion about passives but still not sure what to do. Does anybody own the Placette (or any other passive) and what does it do to the sound versus having an active pre-amp or cd directly into the amps? I don't own a turntable right now, but will be getting one down the road, so I may need a pre-amp?
