The non-twenty versions were good, but the twenties are great. I had recently a friend over who has the R-series, now he feels he has to upgrade his as well, as the difference between the non-twenty R series and 5/20 series is getting quite small

.
I upgraded my VX-5 to twenty mid last year and it was my best ever value-for-money hi-end investment. On the pre-side I went from K-5 xe MP to the KX-5/20. The interesting thing was, that prior to the twenty upgrade the VX-5 was not getting the full potential out of the KX-5/20.
On the upgrade policy I totally agree, a great way to get life time customers. Who else has that nowadays? This is also what I have tried to get Alon Wolf to understand: If people pay 30-50K for speakers, they might do grudgingly one upgrade cycle while still enamored with the brand. But if you expect people to re-do such an investment every four years, while losing minimum 50% on their initial investment, they will eventually walk away and Magico will remain a niche forever. Would he however enable upgrades for the S-series for a third or even half of the new price, he would be able to develop a more sustainable and longer term following. Upgrades can of course be sold through the same people who sell them new, that's how Ayre does it.
This is also quite easy to rationalise mathematically: Just calculate the Cournot-Point between how many new purchases he will lose when offering upgrades vs. how many more will stay with the brand when an upgrade path is provided and how many more will buy new because of the sustainability of investing in Magico products. - Apologies for the rambling, my first Masters was in Economics [emoji4].
