Miracle by Joseph long on Dynavector XX2MKII cartridge

Dan - enjoy it ! revel in it, lavish praise..celebrate the music and the black disc…. i always enjoy your posts… spelling is optional… but i am just a cave man amidst the brilliant

Of course I knew you’d made an innocent typo error. I think there is a Korean or Japanese company whose name at least begins with “Kom…”, who make earth moving equipment. Anyway, what cantilever and stylus has you so ecstatic?

I have had a few conversations with Joseph about the finer points of retipping and would not hesitate to recommend him.  He is a genuine problem solver and the stories on his instagram page lay out his capabilities.

My only (minor and amusing actually) issue with Joseph was that when I discussed with him the re-tipping of my Koetsu Urushi, he laid out so many possibilities, nearly any combo of cantilever and stylus shape that one can think of, that I felt confused when I really wanted some guidance. He did seem like a fine person, and I would readily use his services. Partly for this reason, I would STILL like to know what cantilever and stylus shape were chosen by Islandman.

Hello Lewm,

I heard from Joseph twice, first was: Nude 3/80 micron Orbray microridge.

Second was a long missive:

If I may interject some information: Your cartridge had a broken suspension wire which necessitated a full rebuild. If all it needed was  a new cantilever or diamond, I would have used an original exact replacement Ogura r/R70/30 uM (micron) Vital Line contact diamond, but to save time and expense , I used an extremely high quality Orbray (formerly Naniki) suspension block/tie wire/coil frame/cantilever subassembly.

The coil frame on this unit is thinner than the original Dynavector unit so there will be a savings of moving mass with improved tracking ability. I could have rebuilt it using the original and knew everything else, but this takes a very long time and adds unnecessary expense to the repair.

The frame has no wire on it, so I wound by hand new coils ~50 AWG halogen free high-purity silver-plated oxygen-free copper coils 50 turns per channel with a resulting internal impedence matched to 7 ohms. Original spec is 6 ohms  so pretty  close Output is adequate , I estimate 0.3 to 0.35 mV to the original rated .28 mV. The diamond that comes on the subassembly is a nude r/R 3/80 Orbray Micro Ridge, that is 0.1x0.1 mm square and 0.3 mm tall. It is lower mass than the original diamond and an extended line contact of the PF. The lower mass will impart a more delicate nuanced quality that the larger Ougra and also pick up more detail due to much finer scanning edge spec'd to to be anywhere between 2 and 3 um by the manufacturer.

I reused your original elastomer suspension because it was in excellent condition. 

I hope you don't mind me coming in and filling in these details. You have been an absolute pleasure to work with, so polite, nice, enthusiastic, patient, and charming.

I certainly hope this will not be the last cartridge you will ever mount.

Thanks for being you, and God bless.

Joseph 

So, lewm, I hope this answers the questions you were wondering about.
