Lew,
I'm sorry we missed each other earlier this month.
Kevin is launching a company with a retail distribution model - Sonus Veritas. This is likely what you're alluding to.
John fairly well nails it - that the K&K Max will evolve more quickly as Kevin learns more from his explorations into this realm.
It's unrealistic for a retail product to undergo changes as quickly as a product designed for someone with soldering skills. Where changes to the DIY product are welcomed, a manufacturer runs the risk of being perceived as being only interested in improving his cash flow if he offers upgrades too frequently.
Manufacturers have to walk a fine line - much as they'd like everyone to have their current work.
If I were a betting man, I'd guess that the time will come very soon, where Kevin will stop offering a build service for these phono stages - selling them either in kit form or possibly discontinuing them.
I doubt he'd want to compete against his Sonus Veritas line. Of course, if he saves a few "tricks" for the Sonus Veritas line, then he'll have no issue and will be able to address two different markets - the DIY-er and the retail mode.
As has been said before, Kevin is a straight-shooter, and I have never hesitated to send my customers in his direction.
Cheers,
Thom @ Galibier
