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.
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.
