Pretty similar. It would've been interesting to hear a silver plated Supreme next to the gold plated; I wonde, is the gold plated horn bare metal, or lacquered? If it's bare metal, I think that a silver plated-no lacquer-horn might sound about the same. I'll bet the lacquer on the solid silver horn tones it down a bit. But-how could one tell? Unlikely that a new, silver Selmer would have the lacquer stripped off! The plain lacquered version-to me, anyway-sounds more like a VI. You sound very good on all of them. It'd be interesting if you had the opportunity to play them all for a few weeks, see what you might think then. Personally, I prefer the VI and the Super 20. Might not be a popular sentiment, but there it is. Thank you for putting this together!
One of the most important aspects of a wind synth/controller is how sensitive and how well the mouthpiece functions and it is a pity this aspect is not covered. The octave changing function is also vital in terms of ease of use. I use an EWI Solo and the Akai roller system does take a bit of getting used to but once mastered is very intuitive. Overall the instrument is great to play and good value for money.
