Electra Tube Connectors and GR Research Speaker Update Kits

  Has anyone here used one of GR Research' update kits for speakers?  My first issue is with the Tube Connectors.  Danny at GR claims them to be a superior product to everything else out their.  I cannot find any data or reviews that bolster his claim about their superiority over a high quality binding post.  The only review that I  found was with a speaker system with the cheapest quality binding posts.  I found the review useless.
  The second point is the price of the parts replacement kit.  I have not priced out the parts ( six Sonic Caps & eight better resistors, "No Rez" damping material ) but was wondering what the  the price difference between purchasing them my self as opposed to the kit.  Parts are simple swaps of the same value with the exception of a resistor on the tweeters which have a slightly lower value to raise its response.

One of the differences is support from GR and the GR community.

Second you get Danny's improvement. I'm sure there are better ways to do things. At his price point and the improvement he offers, is it worth it to you? He already did the testing and made mods that work.

The question is do you think it's out of the goodness of his heart? Or do you think he should get paid for improving YOUR speakers..

As far as the tube connectors. Binding post are always better. Pure red copper studs, red copper nuts and washers.  Red copper with mill spec pure silver clad studs, washers and nuts with mill spec silver the same way.. Pure silver studs nuts and washers. Yes they cost a few bucks.
You get what you pay for...

Danny has a preference for "No Rez". For practical purposes and selling kits. NO Rez has a neatness to it.. and an all-in-one solution too. It is a good product..

I like sound coat and black hole. I use course fiberglass for bass. I use sound coat and highland wool for mids. My tweeters are either dipole or enclosed so the housing just needs an opening, no dampening..
