Any Amps with Volume control??

I don't know what your price range is but David Berning makes an amplifier with a very high quality volume control. The model # is the ZH270. I have heard this thing and it is amazing. In fact David Berning designed it to be used direct from source. This amp is like the Swiss army knife of amplifiers, in that you can also adjust the feedback for desired listening tastes. It is an otl tube amp that produces 70 watts into 8 ohms. It is quite expensive, will run $4500 big ones, but man is it worth it.

some of the older Carver amps have volume controls them

If you can get by on 12 tube watts per channel, Audion has a little amp with one line input and a volume pot. I would call it an integrated though. It is a nice sounding amp and retails for around $1200.00. I would only buy it new as there have been some good upgrades performed in the past six months on the model and you would want an up to date version.

Some of the former NAD products had these. I have used a 2600A, and gotten many wonderful sounding years out of it. I recall Parasound also having these. If you want an SET amp, Audio Electron Supply(Cary) has two. One is the SE-811A, which I have heard, and sounds great. The other is the same amp using the 845 tube(maybe 27 - 32 watts), which I have not heard.

Acurus makes a unit called a DIA 150 (DIA = Direct Input Amplifier). This is a 150 wpc unit. You can get information at their site (http://www.mondialdesigns.com). I haven't heard this particular unit, but Acurus is a sister company to Aragon (both are divisions of Mondial Designs), and both are considered to make high quality gear at real world prices.
