Mainly two reasons have led us to create Die Hard line.

First of all, our initial success came from musical accessories such as cables and connectors, which are basic complementary elements, necessary even to the most sophisticated equipment.
Today PROEL is one of the major company in this field, with a considerable competitiveness thanks to its high quality standards.

We have always enhanced our Research and Development: our departments are more and more focused on the opportunities of anticipating market trends, offering to our customers innovative or even revolutionary items, according to the concept of "total quality.

To make a system efficient, we have to carefully consider what can seem "worthless", such as cables, which instead need to be processed with great accuracy.

Cables quality can affect a live performance, that can be more or less successful according to sound transparency. What makes Die Hard cables different from the standard ones is the selection of pure materials, distinctive patterns as well as unprecedented product design's accuracy and constant quality monitoring, all elements that have allowed us to follow closely the signal integrity.

Our difficult but successful Die Hard project is a unique example of cables delivering the most neutral, transparent, fluid and dynamic sound, overcoming any possible distortion.
