Allnic Gel tube dampers

Hi All!
I was wondering if anyone has purchased these items and what they're reactions have been...Good or bad...:)
I have 2 Vac 300.1's and was wondering if this product would be benificial and needed on ALL tubes?
Lastly, is there a better or [in this economy!] cheaper product that gets you almost all the way there?

Many thanks,

If you are going for cheaper and effective you need to look no further than Herbie's Audio Lab Tube Dampers in their various iterations. They can be found at: Herbie's Audio Lab Tube Dampers

I would second Herbie's dampers. Very good value and nice people to deal with.
