new design of tube damper from ARC ?
Yes. Tons. I dumped my ARC silicone rubber rings on all the tubes in my Ref 40 preamp a few years ago. Herbies RX on all tubes on preamp and amp (28 Tubes). Sublime. Tonal balance is much improved as are other aspects. Place the RX damper on the 6H30 tubes as high on the tube as you can w/o them falling off. Much better than the placement ARC recommends on the tubes. Give the dampers at lest 25/30 hrs on time to settle. There’s a 30 return guarantee on them so it’s easy to tell.
Note I also have them on the 6550 Tubes in the power supply. Place them level with the getter.
You’ll be glad you did. The ARC dampers somewhat throttle the ultimate potential of the tube.
