Need Help From The Resident Experts

My problem:

My preamp puts out 30db of gain and the output impedance is 1.2K ohms.  My power amp input impedance is 22K ohms.  I can only use 1/4th of the volume controls (9 o'clock) and it is too loud after that point.  What would be the ideal output impedance for the preamp to mate well with the power amp?  Components in question are an Audible Illusions Modulus 3B and an Odyssey Stratos Extreme+++.  I would like to use more of the volume range and am open to a different pre.

Parasound P7 then, or the JC 2 BP

I can attest that the P7 is pretty neutral and quiet, with an excellent remote and useful bass management. Kal Rubinson I think at Stereophile really likes it and uses it when his ARC multichannel pre is out.

The volume is digitally controlled, but analog. Steps are about 1.1 db or so per step. I measured this a long time ago and am hazy on the exact details. :)

Rogue preamps that use the 12AU7 tube have a rather neutral sonic signature with good bass extension. They respond well to tube rolling.
Very well built products.

...another reason to get the amp and preamp from the same manufacturer

Cary AES has 6db gain or unity.
Not sure of output impedance, but it's very transparent and clean.

I spoke with John Rutan at Audio Connection and I will be traveling there Saturday to audition the Belles Aria preamp.  I  may also audition the Rogue RP-5 if the Aria doesn't float my boat.  Thanks to all for their input, the information I received was very valuable to me.  Truly appreciated.
