Why is the Shelter 501 mono so expensive?

With hand-built cartridges that are built by one person (as is the case with us, and I assume Shelter), the builder works most efficiently when he is building a single type of cartridge, in continuous production-line fashion.

Having different models in the lineup detracts from the builder's work efficiency, and results in less production capacity. But since a cartridge brand needs a variety of models, the normal practice is for the builder to work on reasonably-sized batches of cartridges all of the same type, with different cartridge models being made in individual production batches.

Usually a cartridge builder won't want to work on different cartridge models at the same time, as each model will require different parts, different tools and different procedures, which slows the overall building down and increases the likelihood of errors, and some of those errors can be expensive. For example, if the builder mistakingly puts stereo coils into a body that has already been silkcreened as "Mono" and solders the connections in, at the very least the cantilever and coil assembly will have to be thown away.

For cartridge models that are in high demand, having multiple cartridge models isn't so much of a problem, as each batch of cartridges can be large enough to keep the builder's efficiency high. But with cartridge models that are in much lower demand (as is the case with mono cartridges), the batches wil be small enough to not lend themselves to efficient building.

Also, the parts for a mono cartridge are different from a stereo version, and will be ordered in much smaller quantities (in consideration of the lower demand). The cartridge builder has to pay more for small-quantity items (and may have to wait longer for them to arrive), and mono cartridge parts definitely fall into this category.

All of the above means that for a cartridge builder, having mono cartridges in the product lineup is counterproductive for efficiency of time and cost spent, and therefore business. That's why a mono cartridge will be sold for more than its stereo equivalent (as would be the case with any semi-customized, low-demand model). The difference in pricing surcharges that various cartridge manufacturers list for their mono cartridges as opposed to the stereo equivalents will be tied to how negatively they each evaluate the reduced efficiency in time and cost.

Cheaper cartridges like the Denons aren't hand-made (AFAIK) and likely are made and sold in greater volume, and therefore the above may not apply.

I really don't understand the hand made argument, if they are being made by hand then simply run off a dozen or so occasionally to keep in stock. Having come from the era when mono was turning into stereo I well remember all the arguments advanced for the increase in price for stereo ones. They simply have a harder task to perform than the mono ones and the mono can be intrinsically cheaper in material or at the very worst certainly not more. Twice as much seems out of line and an example of the old adage " When the market shrinks raise the price".

I forgot to add that I am a dealer for VDH and Dynavector and I have not noted any quantity discount on my price sheets. I seriously doubt if many dealers keep large numbers of cartridges in stock in these economic times. While I use to order 4 Supex 901s at a time to get the best price [87.50] that was long ago and far away.

Stanwal, no, what happens is that the cartridge builder is usually overworked with normal orders, and there won't be sufficient open time to insert orders that don't have clear customers for.

Also a dozen cartridges isn't enough for efficient production - you want to be around double that.

Your statement that "mono can be intrinsically cheaper in material" depends on the quality standards of the manufacturer. If the manufacturer is willing to settle for a lower level of quality for the mono cartridges as opposed to the stereo versions, the mono cartridge may be cheaper to make. But if not, and the mono cartridge is made to the same standards of quality as the stereo version, the cost of the smaller-volume mono will be higher.

Incidentally, the biggest problem with the hand-made MC cartridge industry in Japan is not enough builders - everyone that I know is fully booked and working well into overtime. Although the production capacity of an experienced cartridge builder will vary depending on the complexity of the designs that he is asked to build, and some builders can work at a faster pace than others, I'd say that the maximum number of cartridges that an experienced cartridge builder can make in one years' time is around 1000 - 1200 (and that includes everything - rebuilds and repairs as well as new production, and for all brands that he is responsible for). Since that number needs to cover world-wide demand, it doesn't take much sales to saturate the production capacities of a single builder. 4 cartridges sold worldwide a day will do it.
