Reduced: Silvercore MC Pro pure Siver wired Step Up Transformer, SUT

Original owner, over $4,500 new (not included the upgraded feet) if you can find one.

The MC Pro is Silvercore’s flagship Step up transformer, made with the greatest attention to detail possible. It uses 99.99% pure silver wire custom drawn to their specification and large amorphous toroidal cores resulting in a primary winding with an incredibly low 0.1 Ohm DC resistance.

THE RESPONSE OF THE TRANSFORMERS IS EXTREMELY FLAT MEANING THERE’S NO NEED FOR LOADING RESISTORS WHICH WILL RESULT IN A VERY DYNAMIC SOUND QUALITY.  Audiophiles often spend considerable amounts of money on cartridges, preamps, amps, speakers and cabling, etc.  This unit protects the signal at its most important & delicate point, like none other.

Rare unobtanium reference unit.  Large silver-wired mu-shielded lowest DC transformers.  White delrin and stainless case. 
This particular specimen has factory upgraded.vibration damping feet. Among the finest available.  Exquisite.
 

The “mc pro” sets a new standard for the transmission capabilities of mc-transformers. With its uncompromising design, our decades-long experience and the use of the very best materials we have created a candidate for the worlds best mc-transformer.

In theory an ideal transformer has zero winding resistance and a core material with very little magnetic loss. Our “mc pro” comes very, very close to this ideal with its lavishly over dimensioned nano-cristalline toroidal and a primary winding of custom made litz wire with an unbelievably low DC resistance of 0,1 ohms. This minimal DC resistance does not only dampen the musical signal much lesser, it can also increase gain and will thus play more dynamic due to these low losses. The signal will only travel through the transformer and will not be additionally damped. These transformers have an extremely high resonance frequency. This and their extremely linear frequency response allow us to completely omit internal adjustment resistors. The transformers are housed in mu-metal cans to completely isolate them from external interferences.

The “mc pro” is offered in two varieties with different turns-ratio and impedance, to be able to match it to every cartridge on the market.

Variants

These are all the varieties:

▪ 100 ohms / 1:10 is a rather universal mc transformer suitable for cartridges with an internal impedance up to 40 ohms and an output voltage between 250 and 750µV
▪ 25 ohms / 1:20 for cartridges with a lower internal impedance up to 12 ohms that require more gain, thus have an output voltage between 150 and 400µV
▪ EMT special – optimized for the classic EMT cartridges with a turns ratio of 1:20
▪ SPU special – specially wound with a turns ratio of 1:20 for the classical Ortofon SPU cartridges

Of course we will wind a custom transformer for your personal favorite cartridge.

Cabinet

Different cabinet varieties are offered:

▪ Either black or white Delrin with high gloss polished stainless steel front- and back panels, engraved by hand, for a merely resonance free enclosure
▪ Black Acrylic which looks really classy but is rather sensitive to scratches etc.
▪ Individual wooden frames are available on special request. The wooden frames made of makassah wood with an 8-fold glossy polished surface are in a class of their own and underline the high quality appearance of this exceptional transformer

Terminals

Since each device is individually built, special requests such. 5-pin XLR sockets in the input are possible.
