At NAMM 2020, manufacturer Serrano Audio sent out its love letter to Berlin mic making with the Serrano 87.


Serrano 87

It’s a fully custom-made replica of a very famous mic with hand-made K87 capsule and SER-T13 transformer (manufactured in USA), original 2N3819FET amplifier biased to genuine spec, and Styroflex capacitors.

The diaphragm is made on a vintage sputtering machine using platinum of 1-micron thickness. This, says Serrano, results in sound quality matching that of a genuine K87. The SER-T13 transformer is made after a genuine BV-13 unit as found in the U87i microphone. Again, everything is being wound and spurred in the United States. The mic itself offers three switchable polar patterns.

All in all, a no-compromise approach to honoring some historically fine German microphones. Then again, you’d be right to ask about the price…

Price and release

Turns out you are in for a nice surprise. The first 25 units are priced USD 600, then the price becomes a still manageable USD 800. Shipping is scheduled for March 2020. Pretty brilliant, I think!
