How should we know xExio you didn't say how much you paid for it lol. Do you mean is it a nice tune , Yea I think it's pretty well reviewed as being very highly sound quality so says Salvatore and I'm pretty sure he is one of the top 3 people having listened to nearly every tube so..
Amperex 7308 White Label PQ: Combines the best qualities of both orange globe and telefunken. Feels natural and has proper punch when needed. The bass is simply perfect and the overall sound manages to be very transparent, airy and highly detailed without being cold. Lots of layers which help you discover new interesting things from your favorite tracks. This tube just seems to have it all. Listen some quality jazz recordings and you can easily hear all the brushes and strokes of individual instruments.
Sound stage: ****½
Total: 13½ / 15"
