Gini LS3/5a mods?

An online search indicates that Pete Riggle discusses modifying the Gini LS3/5a in a review called Hi-Fi Reader. Thus, two questions:

1. Is anyone familiar with the nature of these mods; and
2. Is anyone familiar with any other mods to the Gini/Ho's/Audio Space LS3/5a?

I'm quite pleased with my pair but am rather curious nevertheless.
