BEL 1001 MK V PREamp Match?


I recently purchased a BEL 1001 MKv. Was manufactured in 2007 so is not old in amplifier years. I am currently driving it with a Audible Illusions Modulus 3a. I am not sure that this pre is the best fit as it has a high output impedance (~1600 ohms). I have not been able to find input impeadance specs on the BEL. Any thoughts? Thanks in advance.

I have a Modulus 3A and a Modulus 3B in 2 different systems. The 3A has been used with 2 Classe amps, a 10 and a 15, an Adcom amp, a McCormack DNA 1 amp. The Modulus 3B is being used with an Odyssey Stratos Extreme Plus+++. No problems at all with any of the amps, preamps combo.
The input impedance for the BEL run in stereo is 27 kilohm 200pf according to the owner's manual. I do not know what 200pf means.
The input impedance of my amp is 22K ohms and it was used with a Modulus 3A and now a Modulus 3B. It is 100% perfectly compatible. The Bel will be a perfect match.
