Rar1 describes the problem very well. On my cambridge, the remote is useless for volume control. Adjusting it by hand is very difficult. I went and took another look at the amp last night. The volume knob has a little play when you rock it back and forth. About 1/8 to 1/4 inch each way would be my best guess. After that you feel the normal amount of pressure that the knob should have. What makes this problem so difficult is that the play is so loose that the slightest touch moves the knob; and it also adjusts volume within the range of play. Something tells me I may be able to make some type of adjustment. Other people would have complained about this. I need a very small torx wrench that I do not have. I will post back in a day or so with the results. To answer Knownothing's question. Given my own preference for sound quality, I don't think you can do much better for the money. I use it for a 2nd system, and in that context, I like it. I have had 4 integrated amps in my home in the last year or so. I thought it was much better than a Nait51. Compared to a Musical Fidelity A3.5, I like the Cambridge a little better for sound quality but the MF has a lot of power. It would depend more on the system. They sound very different. For my tastes, the Creek 5350SE is a big step up in sound quality. I could go on and say a lot about each of these, but is there is anything specific that you need to know about any of those amps, let me know. You cant go wrong with the 640A V2 (not counting the volume knob). Also, last time I checked Amazon, you can get one new for $400. It lists for $700.
