I checked this out in the morning, before my brain had fully clicked in (I find I need a couple hours to get up to speed these days, and then, by about noon or 1, I'm slowing down again!!!), so I tried to identify a particular sound. The tone of the 3rd horn in the first song (My Shining Hour) was noticeably different, so I tried to identify it in the following ones, and ended up being right 2 out of the 3 times. It was the relacquered horn with its own neck. It sounded, not darker really, but more covered or perhaps more resistant. Very slight difference, but audible. I was wrong in the third tune, but the differences were even more slight there. And too, it could be I was more interested in my coffee by then... I was listening on a cheap Yamaha sound bar attached to my TV, and of course YouTube sound is preprocessed considerably. Maybe on my good headphones I could tell more, but maybe not.
In any case, as everyone else has said, you sound just great on any of those combinations, and unless in a setting like this, with one played right after the other, I would be hard pressed to notice a difference. I've heard bigger differences in tone from just switching a reed, so it's all just a tossup.
You should go on mythbusters...
I remain, yours truly, a DP fanboy,
PS - you owe me $365 - because of your playing on that 10M Fan mouthpiece, I had to get one for myself. It's fabulous, but it's all your fault!
