best tube preamp under a 1000 for B&K 200 sonatas?

+1 Quicksilver, < 300 ohms output
Audible Illusions line1, 2 ~1600 ohms output
Jolida Fusion has both RCA and balanced outs, if one comes up used,

I am driving a BEL 1001 MK5 having 22K ohms input with Aubilbe Illsions 3a with no problem, 2M interconnects.

I could be mistaken, but I seem to remember that the B&K M200's having a fair low input impedance of 22K(?) Ohms.

you're very close - the published spec is 24.3 Kohms

Mesch,

Not to get off topic, but I haven't thought about BEL for a long time until I saw your post. Are they still in business? I almost bought a pair of 1001's myself. They were one of the best solid state amps I've ever heard.

I would also reccomend the mapleshade, space tech, or beleive it or not a fisher 400c if mechancial condition could be verified.

However for just over 1k i would strongly consider trying to get hold of a joule electra la100

Zd542, Mr. Richard Brown passed away in 2009. one Sal Zambrano of Audio Summa manufactures some of the BEL cables and offers repair for the 1001. I have not contacted him so know little else. I have read many of your comment over many threads and have appreciated your input. I have only followed this forum over the last couple months. very enjoyable and educational. Thanks.
