VAC Sigma Preamplifier Front Meter / Thoughts / MC Cartridge


So I did a search of Audiogon to find info on my Preamp because usually I post something and people say this has come up before search it .. So I did and there is nothing on my Preamp the  VAC Sigma Preamplifier.
My question is what is the meter on the front panel for ?
I have the manual and it doesn't mention it at all it is just there . Whats it for ?
I bought the Preamp used from ebay local to me seller great guy explained a lot and was right Its a great sounding preamp. I was wondering if anyone else has experience with this preamp it seems rare. Its a dead silent preamp with great sound a big improvement over my past Preamps the Rouge 66 Magnum ( What a Joke ) Conrad Johnson PV-10 (Good ) and the Conrad Johnson REF 3 (Great Preamp) 
So was wondering if anyone has thought on this preamp ?
And lastly anyone with experience with it for a MC Cartridge recommendation I have a High Output denon MC cartridge 110 I think it is and it sounds great but looking more for a low output MC being it is set up for either a MM or MC. I find that with the Denon HO MC If I use the MM input I have to turn the Volume quite High like from 1/2 to 3/4 Vol If I switch it to MC on the preamp Its the opposite problem I barely turn the Vol up and its loud and seems to sound better with the MM input . So I was looking for a recommended Low Output MC Cartridge I would say in the 1000 Dollar range or less that works well with this preamp.
OK Thanks for any input

If you make the switch to a low output MC be prepared for a 50-60 hour break-in for the step up transformer if that input has not been used before.  My experience as a VAC owner.
