I am probably ordering a couple pairs, but the continual changing of design is maybe of some concern.
I don't mean any disrespect, but it is simply hard to sort out the various iterations and connections with others (Wolf, Hoffman, etc) of this designer and the various builds over the past couple of years.
All manufacturers do so in some sort of cycle (one year/two years/five years), but it is kind of unsettling and actually can make one confused if it is done as often as seemingly has occurred this Spring/Summer.
It begs the questions "Does Grover have a reference in mind?"
"Does Grover establish in his mind what is his ideal sound he is seeking ?"
"What actually is this presentation being sought?"
"What is the design philosophy?"
"Will a new design come out in September 2007 that is "light years beyond" the old April/June 2007 "S" version"
The Money back guarantee is a good thing and by all reports Grover is an ethical businessman and a nice guy. Maybe a website with product offerings, some design details, and reviews would help allay some concerns. As it is-I envision a really high energy hard working guy in his basement or garage workshop making cables who gets a new idea every few months.
Not sure we know too much other than they are white techflex, have newer higher silver content connectors, use some combo of silver and copper wire, and they are 20pf. per foot capacitance, and are known for being monsters at detail retrieval.
We don't know what insulation and shielding is used, if it is stranded versus solid wire, how the connector creates synergy, what it mates best with, why there are not different versions (silver, copper, more copper, more silver, better wire at different price points, etc) for different needs or applications, etc.
Anyway, I am sure the business model will sort itself out.
The price of admission is pretty reasonable which allows this business model to work I think.
Anything higher and it would probably not.
The bottom line is people seem to really like the cables and they do reportedly work in a variety of applications, and there are very few who are coming on here and saying they are not impressed.
