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.

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.

I thank each of you for your responses. I have been led to believe that the higher the amp input/preamp output ratio the better and that around 50K common for amplifiers and <600 was common for preamplifiers. I am not sure on this. Make me curious as to the range of amplifier input vs. preamp output impedances. Most importantly, after spending some time with the BEL and 3A i am happy with the sound. Must say that I enjoy the interactions this forum provides. Thanks again.

I used an AI2C with my BEL 1001 (Mark I) for many years and it sounded wonderful. Regardless of the impedance ratio rules I think that they match up well, and I would be cautious about replacing the Audible Illusions...
