Are MC step-up transformers better?

I haven't tried the T-30, but if it is anything like my T-5000, then I'm sure it sounds great! I was on Ebay last night and typed in Ortofon. I found 4 transformers for sale: T-2000, T-3000, T-5000, and a T-20 MkII. A friend ownes a Forsell Air Force One turntable with a Koetsu Onyx Platinum Diamond cartridge (life must be rough!). Anyway, we tried my Ortofon transformer with his Koetsu and it sounded great! So, it appears that they will work well with other cartridges besides their own. Another thing to keep in mind when shopping for transformers is impedance matching. Some MC's have a low internal impedance (sub 10 ohms) while other are somewhat higher (30-50 ohms). Typically, a higher gain transformer likes to see a low impedance cartridge, due to the turns ratio and subsequently reflected input impedance.

Does anyone use a step-up with a Benz Ruby 2? Please give details.

Audio Note Step-up Transformer is the way to go. Try the silve wired wound ones. Will blow your brains out.
