Who makes the best passive volume control?

George, a passive is a volume control. Long interconnects can give you problems as the source must drive the amp with no help from a pre-amp. With some source and amps you would have no problem with 3 meter interconnects. It all depends on many things, speaker used will also have an effect on how it works out. It's a great way to fly when it does work.

There is no best of anything in audio, there are only opinions. Passives come in all prices so I would start looking for one in your price range. There are a couple of passives that sell for over $4,000 I think, the three I hear the most about are the silver rock, placette, bent tvc. There was a couple of shoot outs on these over at AA forum and I think there was one here also, I would do a search on both forums. I think these three can be had for between $1000-$2000 depending on options. Adcom has an active/passive pre-amp that is very good and can be found used at around $750. Creek and E.T. audio have good lower priced models that are good at their price point.

Sorry, that passive should read F.T. audio.
