How to calculate the Step-up gain for MC cartridges.
The gain of a step-up is specified in dBs. When you multiply the gain of the step-up with the output voltage of your element, you have the gain at the Phono amplifier. For most elements up to 0.35 mVolt output voltage you need a step-up ratio of 1:20 (27 dB). Above 0.35 mVolt a step-up ratio of 1:10 (20 dB) is recommended.

Turn Ratio: 1:20

T.H.D.: 20 Hz: <0,006 %
High Permeability Nickel Core.
Double Shielded.

One word: Enchanting!
When I unpacked the red jewelry box and connected it to my system, I was ill prepared for the shock – and awe – of a lifetime. In duet with my Shindo Giscours preamplifier, which is in a much, much higher price bracket, the pair sang more beautifully than any choral work and presented music in a full-bodied way than did Ben Webster when he ‘met’ Gerry Mulligan. Your creation is, it would seem, now the most important link in the chain of my arguably ‘high-end’ system. And all of this for a price which can only arise out of a philosophy and not a marketing strategy. You have indeed reached out to the mass with a true ‘audiophile’ component, a jewel of a product Für Das Volk.

Great Transformer! I makes my SPU meister MKII sing ! It beats the triple priced Ortofon ST80 in musical performance with an SPU. Highly recommended!
