Placette 100K volume control, problem solved


I'm now controlling my digital via a laptop, but it is a pain without remote volume when jumping from song to song since the volume varies so much from album to album. I wanted to add a remote volume control and having heard the Placette before it was at the top of my list. My system has plenty of gain so I really don't need an active stage. Up to this point I was using an Alps pot at the input of my DIY amp to control volume.

My problem was my phono stage has a high output impedance (about 3.5K) so the stock Placette wouldn't work with it's relatively low input impedance. They built a unit for me that has 100K input impedance and it is truly wonderful. A small price premium since the larger resistors are more expensive but well worth it.

The first thing I noticed was how much quieter the system is with no music playing. Then when it does start there is greater transparency and flow than with the Alps pot. I struggle a bit when trying to describe the sound of things, but suffice it to say that this RVC sounds like nothing. I've tried various pots, transformer controls which added noise, and the stock Placette which choked the life out of my phono stage due to it's low input impedance. This unit is perfect for my system.

Forget what you’ve heard about poor dynamics and the other knocks on passives. These things are true if the passive isn’t properly matched to your system, but I’ve got dynamics that will make you jump out of your seat. If you want to try a passive contact Placette. Great people to work with. Highly recommended.

Congrats on your discovery Herman! I completely agree with your acessment of the Placette. I started using one about a month ago and am absolutely amazed and delighted with the results. I liken it to opening a slightly dirty window - there is no longer anything at all in the way. Mine is hooked up to my Odyssey Stratos Dual-Mono playing through Silverline SR-17's. I've tried it on my SET system, but it didn't have as good a synergy with them for some reason. The Sonic Euphoria PLC did sound pretty darn good in that system, but I have to listen some more as I only had one short session with it. In that session I marginally preferred my tube preamp in that system, but the margin was not profound. The effects of the passive were similar with the SET, though there, the tube pre seemed to add just a bit of flesh to the bones that I liked. Again, have to try listening some more. Great solution, and I'd definitely recommend it highly as well. Do be careful in considering passive solutions as system synergy and setup is very critical. The Placette is an amazing value for the money.

Very interesting. I just picked up a Placette myself, but it doesn't seem to be completely happy with either of my sources and feeding into Nuforce amps. I will try some other amps. I once owned a Placette Active, which I wish I had never sold, so I know how this should sound. I am also going to be trying a TVC soon and see how that works out. I'm on a passive kick.
Drubin -
Please explain what you mean by "doesn't seen to be completely happy with either of my sources". I have been switching between a balanced PLC Sonic Euphoria and balanced Placette RVC and my NuForce Ref9s for over 6 months now to get a good feel for each passive's strengths and weaknesses. Both work extremely well in my system with no issues whatsoever. But I am only using a SACD player as the source. What sources are you using?
Drubin - I think both the output of the source, and the input of the amp need to be taken into consideration. I think Herman is far more qualified to speak on that stuff judging from some of his contributions here. Ultimately Guy at Placette would be your best resource. The Nuforce amps have a 47Kohm input. The Placette has a 2Kohm output as I recall. Conventionally that is less than you want for a ratio (I seem to recall a 5:1 minimum), but I think you'd need to factor in the output of your sources. On the system mine sounds best on the input on the amp is only 10Kohms. I believe my source is 3V on the output. The same source downstairs did not work nearly as well with the Placette. Down there my amps have a 300K input. Also, keep your IC's from passive to amp short. I don't know if that's any help in terms of giving any clues as to what may be happening, but I'd say give Guy a call.

I'm using a modfied Marantz CDP and a Dynavector P-75 phono stage, feeding Reference 9SE's, all single-ended. I just got the Placette (the 3-input model) two days ago and I am hearing a lot of what I remember about the Placette "non sound", but I am also noticing bass that, while wonderfully clean, is too light; a very flat soundstage (and very two-dimensional images in general); and an overall character that tends toward thin and light. The active pre I have been using is a Rowland Concerto, which is fairly neutral itself, so this is not a case of having been used to an overly warm and full tube preamp.

A few months ago, when I was using Nuforce 8's, I briefly tried the Sonic Euphoria, just with my CD source. I wanted to love it, but it clearly was a mismatch as it sounded choked, rolled off, all wrong. I don't know why,
