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.

Premium Selected
We call the tubes SELECTED which have passed above tests and thus qualify as reliable all-round tubes of their type.Typically this is around 30-60% from a batch that receives the SELECTED label from TAD.
For applications in particularly sensitive functions such as V1 or input stage with combo amps, V1 in high-gain amps, tube microphones and phono preamps, we recommend using the respective HIGHGRADE selection
