Norman,
Thanks for your interesting description of your personal experience. I agree that 7.5 ips can sound very good and I take your word for it that 2x copying can be essentially perfect. The issue there is whether the hyper-critical audiophile market would accept anything that appears to be a compromise. Several of the premium reissue labels claim that they do regular speed one-to-one dubbing (i.e., only one slave) which means that, if volume increases, some cost savings could be achieved by making more than one copy per pass of the production master (save wear on the master too). Given how much some people are willing to pay for nice rare vinyl discs, I think you are right about $200 being a cost point that may attract some interest. But, it still would probably be a niche market, certainly much smaller than the market for $50 premium 45 rpm vinyl reissues.
