Yes, the difficulty revolves around the different nomenclature we are all using on Head Fi.
The LCD-2's Rev 1 originally had straight down connectors, but the later ones had angled connectors.
The LCD-2 revision 2's (also called the LCD2.2 or LCD 2r2) had the angled wooden connectors and the newer, lighter diaphgram.
You are talking about a revision of a revision: The LCD 2 Revision 2 Revision 2 - which would mean the metal, angled connectors are LCD2.2.2's ...
The difficulty lies with most people here referring to the LCD2 Revision 2 (LCD2.2), as LCD-2 Revision 2.2 (as they are confused by the Revision 2 being labelled an LCD2.2). Most people on HeadFi saying "Revision 2.2" don't mean "Revision 2.2" at all, they mean Version 2.2 (which is actually an LCD-2, Revision 2).
To avoid this confusion, most people don't discuss the Bamboo/Metal connectors as a "Revision" (as there was no change to the driver - well, no OFFICIAL change, though as you point out the treble has increased and the bass maybe decreased during the production run). They will still call them LCD2.2's (LCD Revision 2's) and simply state "with metal connector" or "bamboo" version - which also neatly manages to clear up all the confusion engendered by referring to an LCD-2 Rev 2 Rev 2 or LCD2.2.2.
