STEVE TOYTip: remove those rings from around the valves - they kill dynamics!
Jonathan.I agree Steve, tried some EAT valve dampers on the valves inside my Puresound P10 and didn't like it one bit.
Seemed to go to dry for me.
HI Guys
My findings are different. I have never heard a loss of anything with TUBE RINGS in place. The improvement is small but there is an increase in clarity, openness and detail with slight bass improvement too. Some valves show more improvement than others but all show an improvement. I am with Mike Homar on this one. I have them or similar on nearly all my valve gear.
