Premium Teflon Socket
Chassis-born vibration softens the imaging and veils harmonics, robbing the music of its tonal tapestry. Teflon sockets act as a vibration break for the chassis’ shakes and a damper for airborne vibes.
The PREMIUM Teflon socket also grips the tube pins MUCH better than ordinary Teflon sockets and has a more favorable dielectric characteristic so high notes can soar! This is not a small improvement and I’d put it on the same level as a major cap upgrade, maybe even higher than that.
