DBP-10 Protractor Instructions......

I think you need to reread Art Dudley's article. Art states in that article that the DPP-10 “is still my favorite protractor”, and has been for a number of years. No where in the article does it say that it is overly difficult to use.

As I previously stated, it is certainly not an intuitive system. However, after reading the instructions, and after you've worked with it just once, it becomes rather simple to use. Don't let the fact that it is not easy to use dissuade you from using a very accurate and versatile alignment device.

As far as the Mint Protractor is concerned, I have used that one too. It is very nice, and fairly simple to use, but at the same time it is indeed limited to one table and arm, which for most of us makes it of limited value. (I say most of us, because as audiophiles, we do tend to swap out turntables, tone arms and cartridges on a fairly regular basis.)

Hi Kurt,
It's perhaps the convoluted way that Dudley described the process he went through to align the cartridge on the Schick tonearm that made me totally discouraged from ever using the DBP-10. I got completely lost in the steps and different calculations; when I read "software," I said to myself, "You've got to be kidding me."

As far as system swaps, I can only speak for myself, but the Classic I'm still waiting for might very well be my last table for a long, long time considering the cost of a good analog setup. Once you get up in that turntable and cartridge price range, my guess would be that not many can afford to swap on a "fairly regular basis." I know I can't. Peace.

Dear Actusreus: +++++ " So if you order a protractor for the JMW-9, it will be "made specifically for this arm," based on the Baerwald values. " +++++

that's right and that " specifically " tonearm made protractor can/must be used with any other tonearm that has the same effective length than the JMW-9!!!!!!!

But that IMHO dishonest Mint people let you think that if you have two same effective length pivot tonearms from different manufacturer/designs you need two " specifically made " protractors!!!!!!: these dishonest Mint people are only decieve/cheat/fool you ( and making a fraud ) because your very low knowledge about geometry tonearm/cartridge different algorithm calculations.

These Mint people IMHO only want to take away your money when you can do it for your self by free!!!!!

Any of the geometry algorithms calculations ( Baerwald, Lófgren, Stevenson, etc, etc. ) needs three primary parameters and parameter values: tonearm effective length, innermost groove and outermost grooves.
With these parameters values the final calculations give you: offset angle, stylus overhang, inner null point, outer null point, spindle to pivot distance.

With these final calculations/values you can build your own protractor as you can see in VE or Enjoy the music:

Now, on each one of those different algorithms you can attain at least two different calculations that can give you two protractor choices for the same tonearm.

How is that?, well exist at least two Standards for the innermost/outermost groove values: DIN and IEC, depend which one you choose you will have two different tonearm/cartridge set up parameter values.

Even you can choose your own innermost/outermost values and make three-four or more protractors for the same tonearm for you can decide which one works beter for your specific needs/priorities not for the " specific " Mint need$$$$$$

Raul,

I honestly cannot speak to the charge that Yip (I've only dealt with him when ordering) has any ulterior motives, is dishonest or is driven by greed. As any businessman, he certainly wants to make a profit, but my dealings with him have been nothing but positive.

You make a good point about many different algorithms that can be used to optimize cartridge alignment. However, in my humble opinion, most vinyl enthusiasts, like myself, do not want to deal with calculations, different parameter values, or innermost/outermost groove values, etc. Mint offers a fool-proof setup method using one of the most popular and recognized approaches to cartridge alignment. It's made to a high standard and offers a very precise alignment, something that a printed out paper grid probably could never do.

I think both a blessing and a course about hobby is the fact that we have so many different options when it comes to setting up our analog rigs. For those who love to forever tinker and experiment, an effort to try out the many different protractors and parameters might very well be worthwhile. For those who would prefer to set up their system and adjust as little and only as often as absolutely necessary, devices like the Mint Tractor are God sent. VTA, VTF, azimuth and the overall system synergy already give me enough headache as it is. Peace.

Dear Actusreus: I'm not against " the business man " and profits but against what that " business man " let you and " oriented " for what you understand in good faith.

+++++ " most vinyl enthusiasts, like myself, do not want to deal with calculations, different parameter values, or innermost/outermost groove values, etc " +++++

because of that it is easy to make business with people: why try to make business with deceives.

Anyway, you get my point.
