Agreed, most people at the raves are pretty set on what they have and like.
You may want to try letting the regional audio groups get it for one of their meetings.
I know the California club is very active and they spend.
Your top of the line pre is I believe above 20K , that requires a special buyer with deep pockets and people with access to those types of people.
I know people who build really great stuff, and they want big money for their gear. Selling it is difficult , without a dealer network, marketing, and street cred. And resale value is critical to success for any product. My friend makes great gear but resale is about $1.50. That means alot to someone who spent alot of money.
And todays economy ain't helping. These forums can help alot, but I find they create more of a flavor of the month product, the buzz comes and then it goes, they never have staying power.
Shrinking economy, shrinking market base, and products going up in price create a conundrum...what to do?
Soon only the 1% will only be able to afford high end gear, the way the industry is going, and it seems they want to go only after the 1%. Make the money fast and quick.
Sorry for the tangent, but without a big marketing budget the only way to sell gear would have to be a grass roots movement, get it out there, take your lumps and hope for the best.
I personally know at least 4 other people trying to do the same thing you are trying to do and it is difficult to say the least. I wish you good luck and think you should take your chances with the audio groups, if the product is good it will sell, if not, then Darwin takes over.
