  Thanks Kona, you're a legend! Thanks to you I was able to find the Absolute Sound article. I assumed it was Stereophile since it was my go to audio mag as Absolute Sound wasn't as available in Australia all those years ago.
  
  Here's a link to part two of the series that described the BB pellet tweak. I was impressed with how much effort the authors went to limit subjectivity in evaluating performance improvements. You were right about zinc-coated BBs being critical. Copper BBs made the sound worse through what they proposed was an "inverse faraday effect".

    I've used the technique for years and not due to the article. I found some very small cardboard boxes(from a hobby shop; they look like 2" or so hat boxes) and filled them with BBs. The idea was simply damping the chassis of the gear

      I also have a circular plastic pill box filled with lead shot for the same use on my CHORD DAC. I thought the article was interesting in that they said it wasn't simply due to weight damping since weights alone didn't have the same benefit in their DAC test. The zinc-coated steel BBs were the critical factor. I would love to try this myself but can't seem to be able to find zinc BBs here in Australia so far. I'll keep looking.

    Thanks doublej. Yes that's the very one. I appreciate your constructive reply. Cheers.
