Dear Mordante:
While the assembly of the Dorian was initially planned to be outsourced, this plan was cancelled while the cartridge was still in the prototype stage. Every production Dorian has shipped with Mishima's hands-on TLC.
The Dorian was originally planned to be a lower-cost cartridge, it was planned to be made in higher volumes, and it was planned to be not made by Mishima. To increase component volume and get individual component costs down, the mechanical components of the Dorian shared the same design as the Argo, and were made on the same machines. Anodizing was changed to a less sensitive color than the Argo (nothing is as aggravating as having a perfectly machined body get rendered unusable because of duff anodizing), and we specified a stylus that was as close in dimension and shape to the Argo, but off-the-shelf rather than a custom design (custom designs will always be more expensive).
However, the Dorian project suffered a setback in the assembly phase. I've written previously about what happened here
http://learn.audiogon.com/cgi-bin/fr.pl?eanlg&1268751339&openflup&62&4I kept all of the design aspects of the Dorian, but brought in Akiko Ishiyama as Mishima's apprentice-in-training. As she learned the craft of building MCs over the past 8 years, Akiko has gradually taken on more and more of the early assembly stages of the Dorian. Nonetheless, Mishima does all of the final assembly and voicing work which is critical to the performance and sound. This is true for each and every Dorian that has ever shipped.
The situation is the same with all of the Delos' - the basic assembly is done by Akiko, and the finishing, voicing and measuring is by Mishima. Actually, Akiko is now involved in some of the basic assembly work for the Kleos as well as the Delos, and she continues to do good work.
Since the Dorian was never outsourced, keeping it in our lineup would have indeed been an extra burden on Mishima (and Akiko).
Although the Dorian would still have been cheaper than the Delos if we had kept it in our lineup, rising material, energy, processing etc costs meant that it wouldn't have been much cheaper. I estimate that retail of the Dorian as it was would now need to be US$1300 or thereabouts, and that meant that it would clearly offered much less performance and sound quality for the money than when it was priced at under US$1000.
I didn't feel good about seeing the retail price rise without any accompanying increase in performance, so I pondered various ways to boost performance. OTOH it wouldn't have made sense to increase performance by throwing advanced materials or complex machining at the problem, as this would have bumped the resulting cartridge right out of its intended retail price target. Luckily I had the "New Angle" inspiration, and this made it possible to introduce a Dorian (and Argo) replacement with much-improved performance, for not much more than the Dorian would have ended up costing anyway.
As to how well the Delos performs in comparison to the Dorian, that is going to change depending on what kind of audio system you have and your setup skills. Also when it comes to subjective opinions, there is no wrong or right. Although I've heard (a very few) systems where there wasn't much to choose between the Dorian and Delos, by far and large, I find the Delos to perform at the Helikon class and above.
