The Erse Pulse-X uses a premium grade of defect-free polypropylene film, wound on the latest German designed automated winding machines. The leads are 99.99% pure copper tinned and welded to the body. The precision tension control is the real secret to the exacting tolerances (+/-3%) and control over microphonics.

The combination of superior engineering, use of premium materials and an exacting manufacturing process produces one of the best capacitors in the industry. With tight tolerances, low microphonics and virtually immeasureable distortion these make very neutral and transparent components. They don't add any appriciable sonic character (if your looking for flavor try another method).

The price? Don't let the affordability of these parts fool you. Erse is a company built on OEM business by engineers and real production people. They are priced appropriate to the cost of manufacturing.

Proudly designed and manufactured right here in the USA. I'm proud to support them!
