Help for a novice in picking a preamp

I'm currently using a Musical Designs SP-2B pre with my McCormack DNA 125 and am having issues with lack of volume control. Other than Steve's preamps can anyone suggest a good match in the $1k range new or used.

I'm driving Vandersteen 1cs in a room about 14 x 20 and listen primarily to blues, folk and classical.

I agree with Bob. I would give John a call and let him know what is happening. I am sure he can help you out.
