@oldvinylNot sure what you are referring to. I have an Io Eclipse, but have not added any damping material inside. The side panels are vented grills.
That is actually velcro to secure the top lid. Nothing high tech.@oldvinyl
In this picture you posted, on the interior of the chassis is what appears to be some taped down or glued down material. My assumption it is that is damping material on the chassis rail. My IO does not have that material on the interior chassis rail.

What exactly is the sonic benefit after cleaning pins.
You should use cotton bud cleaning your ears every now and then too Ked. That should gives much more effect than cleaning tube pins.Just clean all your tube pins, cable connectors and plug them back. Once a every few weeks when you remember and have time. Maybe once every few months
The cleaning applies to pins, sockets, cables (power and signal), outlet (with AC off), connectors.What exactly is the sonic benefit after cleaning pins.
And maybe all those evaporating cleaning fluids add a small high that also enhances the sound experience !The cleaning applies to pins, sockets, cables (power and signal), outlet (with AC off), connectors.
Cleaning removes oxidation. This results in a better conduction of electricity, better ground connection.
Benefits: ultra quiet inky jet black background, significant reduction of noise floor, better coherence of sound, more palpable imaging, improves detail (without negative side-effect), smoother high frequency. In short - everything we like about high end audio improves.
Note that this works for solid state amps, power conditioners, and CD players too (cleaning their connectors and cables).
The only overall agreement in audio is that there is no overall agreement.Oldvinyl, thanks for your photos of the cleaning process - very useful. Kcin - you mentioned other methods, with maybe less work?
I will not start cleaning next weekend, but I will do it, the next time I need to open the boxes. Oldvinyl's post made me think of an interview I read with the Lyra cartridge people, Jonathan Carr perhaps, about the need to clean all contacts in the system, and do it thoroughly.
Oldvinyl - your shot shows "standoffs to allow clearance needed for KT66s (in place of EL34)." I have not done this modification in my power supplies. Is there overall agreement that the 66 sounds better than the 34? Plusses and minuses?
