Really? 100K? I always thought that McCormack's were around 10K and Pass around 20K. If your CJ is 200 ohms, you shouldn't have a problem, even with 10K. However, I think you are looking for something with more resolution than CJ.
I've heard the B&K's, but never owned one. I did own a Aragon 4004 mk II many moons ago, it was a nice amp for the $$$. When considering preamps, CJ and Cary are at one end the the tonal spectrum, the rich, warm vibrant end. ARC and VAC are on the other end of the tonal spectrum, the transparent, high resolution end. Audible Illusions is more in the middle, but leans towards the transparent end.
With the 24K inpedence input you should be alright with any preamp with an output impedence under 1Kohm.
What kind of cables are you using? If you're using warm cables like Cardas with warm preamp like CJ and warm speakers like ProAc, that also could be a mitigating factor. Let me know what you think once you get the B&K hooked up.
