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

HIGHGRADE SELECTION
But only those tubes which pass these tests best are labeled Highgrades.

Matching and Selecting Options for Preamp Tubes
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.
