Preludio is an innovative line tube preamp with output transformers.

These are used to obtain an extremely low output impedance to drive at best any power amp.

Another specific feature is the dual output, the first has a gain of +12 db to drive any amplifier with authority and dynamic; the second has a gain of       -12 db and is specifically designed to drive high sensitivity vintage amps like Leak, Quad, etc..

Is understood that, upon request, we can vary output's gain, depending on customer needs.

Prelude's generated noise is very close to zero, this is an important feature for those who use extremely revealing, high-efficiency speakers.
