Years ago, I ordered a Supratek preamp and waited nearly nine months to get it. There were quite a few others who waited nearly as long or longer, as the designer lives in Australia and is (or was) a one-man show. It was a long wait, but worth it in the end.
The difference is that people knew it was going to be a long wait going in. For what it's worth, I would recommend to Eric to "under-promise" and "over-deliver," rather than the other way around. Tell customers to expect their speakers in two weeks and deliver them in six weeks, they'll grouse on the forums or even cancel their orders. Tell those same customers it will take two months to make their speakers and when they get them in six weeks, they'll sing your praises to the heavens. It is the same amount of time, but the perception is completely changed. Just food for thought.
The Supratek preamp was worth the wait. The Double Impacts--and I am sure the Ulfs and mini-Ulfs--are worth the wait. I love mine. They are not just a tremendous value. They are tremendous period.
