I can't get a wood bodied Benz anymore
Cardas myrtle wood is a benz ruby in a myrtle wood body. It is still available. 
Any step up transformers recommendations for MC's
What is the internal impedance of the cartridge. That information is needed to get a good calculation of the step up ratio needed to reach 6.0mV output. 
Soundsmith dl103r vs. Dynavector 17d3 ruby ?
I compared a ZU DL 103R with a ruby cantilever and line contact stylus retip from Soundsmith to a Dynavector 23R with Ruby Cantilever. I have not heard a 17D2 with a ruby cantilever. I must say that the ZU DL-103r with the soundsmith ruby cantilev... 
Can I make the volume louder by using a pre-amp?
Sensitivity is the lowest value that the phono input will amplify correctly. Since the cartridge also has an output of 2.5mV, that is the lowest value that will work correctly. You would have been better off with a higher output phono cartridge. T...

VPI 3D & 10.5i armwand compatibility
I have a demo 3D arm that comes complete with a pivot assembly and tonearm rest bracket if you are interested. It is tested and works fine replacing a standard 10.5 tonearm. The pivot assembly is backwards compatible to the original 10.5 arm, so y... 
phonp pre amp
A transformer won't extend the distance, since it does not amplify the signal. You should put a phono preamp near the turntable with no more than a 1.2 meter run between the turntable and phono preamp. The phono signal is very small (5mV or less f... 
VPI Classic 3 anyone try a Denon 103R
It sounded so good that I demoed the ZU version of the DL-103R on the JMW 10-inch arm at audio shows (ZU DL-103R on the Classic 4). It also worked well on the JMW 12-inch arm. There is also one shown on a recent post on the Asylum by Seadog. I did... 
MC Step Up Math
I personally use 10x as a starting point. It is at the point where the cartridge sounds unconstrained by loading to my ears. I then adjust it lower until it sounds constrained than back it off a bit. With a SUT, use a formula that allows an output...
