In reading the thread, I have tried to think of a better way to improve the buying process. I really like the idea of a trip to Japan for “free” to buy a cartridge! But probably not realistic for many.
Putting aside comments on prices, I think reps should be supplied with a demo unit that can be sent out for trial. Manufacturers should provide the demo to the rep free of charge. The potential buyer would need to provide a security deposit equal to the retail price of the cartridge (yes, the entire price). It must be sent to, and installed by, a turntable tech approved by the rep. The tech's fee for this service is paid for by the potential buyer. The tech would attest that the cartridge was received in perfect condition. The approved tech would need to sign off that he had installed AND removed the cartridge and that there was no change in its condition from when installed and removed (photographic evidence of cantilever condition would be useful). If not, you bought the cartridge, even if it was a demo. There would need to be a time limit, say, 30 days, for the demo.
Is the buyer shouldering a lot of the risk? Yes. But to me, this is an acceptable compromise to be able to try the cartridge out in YOUR system. If there is no approved tech in your area, you may be required to drive a considerable distance (two trips) but this comes with the territory of purchasing an incredibly delicate, expensive device.
OP, would you consider such a service? If not, why?
