I do admire Mr. Wilson's marketing acuity and there are many individuals, like you, who are dedicated followers. I assume you are also a Wilson dealer.
Having said that, I've always had a difficult time with the many versions of the WP and the subsequent price increases thereof. I assume there's a valid reason for it but when Wilson Audio released the WP8 and then came out with the Sasha less than a year afterwards (maybe it was six months) at a reduced price, the marketing philosophy became somewhat untenable, or at best, very difficult for the average person to comprehend. If I had been one who had purchased a WP8, then heard news of the Sasha, I would have been a bit upset to say the least.
I know that Steve (aka Slowgeezer) one of our senior members who was a previous ML'r, has the WP7 and seems to be quite happy with it.
In the end and as validated by the above posts, what matters is what's best for the individual that allows that person to emotionally connect with the music.
