The latest and greatest


Sometimes I see a new product (in this case speakers) that get lots of press and discussion only to see lots of them for sale a little later. 
Right now there are many pairs of Kef LS50s coming up for sale (both the regular and W versions).
Are these just a flash in the pan or just showing up on the market because so many have been sold?
In my mind there is nothing like a product that has stood the test of time. 
Am I just being a sceptic?

Isn’t the LS50 an update on a classic British Broadcasting (LS5?) monitor design? (Might be wrong about that, though) I read KEF was responsible for mftg. the LS5 for some period back in the day.  If the LS5/LS50 "connection" is true, one might argue the LS50 represents a design (if not the exact product) that has indeed stood the test of time.

It is not really an update on the venerable LS3/5a (that was indeed also built by Kef, among many others). That honour goes to the Spendor Classic 3/5, and even more so to the Harbeth P3ESR. The LS50 is a rather different animal, if only because of its co-axial drive unit.
Interesting topic crwindy.  I am concerned that when my "legacy" gear wears out I will not be able to replace it and get the same performance.  Classe, Thiel, vintage CJ as an example.

The latest greatest doesn't always stand the test of time, or get the opportunity.  Manufacturers of high end gear is thinning out, and most of the survivors, in order to survive and even grow, are on high speed innovation programs.  They are training us to always look to upgrade.
