Benz Micro Reference specs
« on: 7 May 2024, 09:28 am »
I have an old treasury Benz Micro Reference, 25+ years old, but without any documentation. Tried to search, no result, producer send me some old document and it says that recommended loading from 1.000 - 47k, which is strange, cannot be matched with mc step up, kind of difficult. 
 
Does anyone have specification for Benz Micro Reference (without s, 2, 3, just plain)?

Searching on Vinyl Engine, it shows internal impedance of 20 ohms, the cartridge likes to see >60 ohm load, and the output is 0.4mV. This should work just fine with a MC SUT. If you have a 1:10 SUT into a 47K input, try that. A 1:15 should be fine as well. If you have the ability to tweak loading resistors, try backing them down to 33K or even 25K with a 1:10 SUT. Benz Micro are weird on their "suggestion" of loading resistance where they really let you run wild to search for perfect values. All in all, this should work great with a SUT.
