Benz micro glider cartridge loading advice needed.


Hello! I hope you are all doing well!

I just purchased a new phono pre amp.

I have an older Benz micro glider moving coil cart with 1.1 mv output.

The pre amp has gain of 45db (mm) up to 65bd (mc).

Load settings for moving coil are: 10, 22, 47, 100, 220,  470, 1k, 22k, 47k.

I know that I should listen for myself to determine the best setting. But can someone with more experience than myself give me a range within which to start based on having used gliders in their systems?

 

Thanks !

Please note that when you switch your SFP1 to MC it inverts phase.

You will need to invert the cartridge connections plus to minus and vice versa on each channel.

Personally I would try 47k and work your way down. I have run this cartridge into 47k with excellent results.

I should have added that, for those who can hear differences in absolute phase,

You should be so lucky.

Unfortunately I hear inverted absolute phase even in foreign systems. David Fletcher of Sumiko the same.

Sadly there are many records where instruments/vocals are out of phase relative to each other - eg you can have clean vocals with fuzzy sax or  vice versa.

Can be annoying.

ESL's are less pronounced than cone speakers.

Absolute phase.

Think of it this way - 

If you have cone speakers and absolute phase is correct the drivers first inpetus is to push out and then back as the signal is applied.

If the absolute phase is reversed the cones first inpetus is to suck in instead of out when the first signal is applied.

When the absolute phase is correct with cone speakers I generally hear a more natural sound, when it is wrong I generally hear a slightly flattened soundstage, and at worst slight compression in the mids.

With electrostatics such as @lewm runs, his speakers, unlike most  cone speakers, are pushing sound both frontwards and backwards so the effect is less apparent.

The problem with Conrad preamps is that most of them invert absolute phase in the line stage, so you simply reverse the + and - connections at the speaker.

However if you have a phono stage that inverts phase ( and the line stage does not ) then you can't reverse the + and - at the speaker because the CD or digital will then be out of absolute phase. In this case the best solution is to reverse the + and - connections on the cartridge for each channel.
