I think that's a tad cynical 😉, the S3 tenor is a very good horn, but having owned both, and currently playing an S3 (last 12 years) I appreciate that they are considerably different in character within the 'Selmer thing'. The S3 is tone-wise quite a bit different to the S2 (which I played for 15 years); it's more tightly focused and lighter to play, and I'm not talking about physical weight (although the S3 is a little less heavy weight-wise due to the absence of body straps etc). The S3 articulates more easily and is easier to obtain a warm core to the sound IMHO. I find the S3 more to my liking because I can do more with the sound, I always found the S2s, although terrific players, a bit less flexible and in a recording studio their sound has a tendency to spread all over the place, more so than any other horn I owned, which can be an issue I suppose.
It's a pity Selmer's quality control has been so utterly rank over the years. They are trying very hard to rectify that, and the not-before-time removal of Vincent Bach as importers in the UK will hopefully see a vast improvement in the standard of Selmer horns in the shops. I think the problem was that Selmer shipped the horns on the understanding that Bach would set them up before sale, but of course that was never done. I went to Bach a couple of years ago to try a handful of S3 sopranos for an insurance claim, and only one out of four was anywhere near playable. In the USA the shops expect to set Selmers up before purchase, in the UK it seems the dealers were not prepared to do this; understandable perhaps, but very bad for business 🙁 and has tended to produce this reaction in smaller dealers......
which is ludicrous, but understandable under the circumstances.
