Ok I know there are a lot of Selmer haters and detractors out there, and others like me that love the core sound of these instruments back in the 80's I couldn't afford one and now I am spoilt, Yes I have a Supreme and I think that the bottom is going to fall out of the MkVI market, which may or may not be good news to some.
The sound is very much a MkVI sound with some major differences the bottom end is the most in tune of all the sax's I have played over the years, the intonation throughout very good not perfect but not far off. High notes and altissimo sound with what feels like less effort and can be played pp. It certainly will shout and holler if you want it to and yet play evenly up and down as sweetly as butter.
What I can say is out of the box it has impressed me the action is noticeably different, and not in a bad way, I would compare this to the difference between a sports car gearbox and an old, (insert ford BMW Vauxhall brand of your choice) family car gearbox it certainly does not take anytime to adapt and I would say improves playing those speedy pieces. Noticeable is the feeling of the front F key when your finger is on the B key its proximity may annoy some but its there when you want it.
I have a good MkVI, I wouldn't dare call it a mythical beast but it has been my go to sax for years and I know its quirks but honestly I can say I am not sure how often it will come out of its case now as the Supreme does all my 6 can and more, it is likely to be more reliable and now only needs a few thousand hours of playing the mech in.
I will try and do some audio comparisons if you guys and girls are interested but I would certainly now change my recommendation of getting a MkVI saying instead save your pennies and get one of these.
On a side note my missus bought one too, and playing together the intonation between sax's in the palm keys is ridiculously close so you can bin that old joke about the definition of a semitone being two alto's playing in unison.
