Placette RVC review in Stereophile


There is a brief review of the Placette Remote Volume Control in the June '04 issue of Stereophile that might be of interest to some folks here. The Passive and Active linestages are also mentioned. It's good see some more recognition for the company in print.

Has anyone heard the active Placette and preferred the passive. I'm now using an RVC, it replaced a CAT Ulitmate MKII (as I only have one hi-output CD source and no phono, and really do like the remote). The RVC is fed by a DAC and plugged into my Merlin BAM, which is a bass augmentation unit for Merlin speakers, and which has 50KOhm input and 200 ohm output impedance (in affect a buffer for the passive - I also use Cardas GR with exceptionally low capacitance). Guy suggested that in this setup, the active might not be much of an improvement. I wonder when the active would be an improvment, and when it would not. Having seen Mike's system in the Virtual section I know he could have gotten an active Placette if he wanted to, but chose not to; so I'm wondering about the difference and reasons for choosing passive versus active in the Placette line.
Pubul57, I have heard both and still believe in my system, that the Active was about 15% to 25% better sonicly then the the passive. But, as we know that last percent in audio still makes a big difference if you can hear it.

I was talking to a designer who has great respect for both the passive and active Placette pieces and the genuis of Guy Hammel's designs, he refers to the Active as a "buffered passive stage" that gives you the best of both worlds, out standing clarity/transparency of passive stages and the dynamics of an active stage.

The Placette Active has no gain, although you can get it if you ask. So it is, effectsively, a buffered passive. I don't think you need sacrifice dynamics with a normal passive line stage, but things need to be carefully matched. With the Active, that problem goes away.
So then what would be ideal matching for a passive to work as well as an active. I guess it is optimizing source output impedance with amp input impecance assuming gain is more than sufficient. But what are those optimal impedances?
