Q: When does a preamp tube become a Premium Selected tube?

 

A: All preamp tubes labeled Premium Selected have passed the following tests:

-      Low Noise Test

-      Microphonic Test

-      Gain Test

-      Sonic Tests

-      Shock Tests

-      Listening Tests

-      Balanced Output Test

 

Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems.

This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.
