Presence Deluxe MK. II, updated 2004. I am aware of the Vishay resistors and their strengths.
As far as the tubes, none of them changed the "bite." The 7308 tubes are warm, but this just softened information. The 6922 Amperex PQ USA gold pins are the most detailed, but bite? Still there.
Your information about the Presence model and the Holcos is exactly my point concerning the "edge": that Rankin decided to use Shinko resistors because he thought "the Holcos had a slight edge to them..." I'm curious about the possibility that changing to the next higher model, which utilizes Vishay, may eliminate the edge.

OK TVAD, I check my Excel chart and I was wrong. There are sadly only 13 (thirteen) First Sound variants.
I constructed the spreadsheet from the 2004 price list with some additional info from the First Sound web page and several reviews. Emmanuel has verified my count.
