Ultra-premium sounD quality


Genuine-CLASS capsule

second to NONE

The importance of capsule quality cannot be overstated. We wanted to find a capsule with that "magic wow" sound quality that we have only found in a genuine K87 capsule. Microphones under $1000 are almost always made completely by machines, which requires major compromise to the performance and sensitivity of the capsule. Each capsule in the Serrano 87 is made by hand, one at a time. This process makes it possible for us to offer a capsule with that exquisite tonal richness and harmonic depth that truly matches the same sound quality of a genuine K87. You will hear the difference.

The Serrano 87 circuit was designed using the genuine vintage 87i schematic. It features the original 2N3819 FET amplifier, properly biased to original specifications. No compromises have been made.​


The SER-T13 transformer in the Serrano 87 simply sounds gorgeous. It was designed after the genuine BV-13 transformer found in the U87i.  Each one is custom made in the USA specifically for the Serrano 87.
