Cambridge 640A V2 Volume Control Issue

I have a Cambridge Audio 640A V2 integrated amp and was wondering if anyone has the same problem with I have with the volume control. When I increase or decrease volume with the remote, it is very difficult, if not impossible, to get it to the loudness I need. If I just tap the up/down button to make a very small change, it overshoots and I end up getting too much volume, or too little than what than what I need. The best way for me to describe what is happening is to say that the control is sloppy or impercise. Also, when I use the volume wheel, it is very sensitive. It only takes a very small adjustment with the wheel, to get a big change in volume. I welcome any comments from anyone that has used this amp.

FWIW I have the same problem with AMC integrated, it over performs in all other categories. I think it is a combination of cheap(er) volume pots and perhaps a slight mismatch in the output of source with amp. Only way to improve is to get higher end integrated amp or pre + amp, or install Rothwell line attenuators:

How is the sound of your amp otherwise?

R1g_audio,

From your last comment - it sounds to me like your problem has more to do with the mechanics of your nob than with the electrical performance of your pot and associated parts. I suggested the Rothwell attenuators because they would reduce the sensitivity of your volume control and give a smaller change in volume for a given rotation of your volume controller. Assuming you do not ever operate your system at full volume - you would probably not notice any negative effect from the increased attenuation other than normal listening occurring at a higher volume setting than before.
