CFz is one of the best MC step-up transformers to recover the rich musicality and highest sounding quality from analog disc.
Based on the silver wire application know-how compiled over many years in transformer winding, CFz is designed to reach full performance of a step-up transformer by using copper wire and a new and original winding technique.
In addition, a strong core, which is with the same design and material as SFz, is used to further improve the sound quality. Result is open and natural sound with stunning freshness, giving delicate expression with wide dynamic range.
