I asked Christopher Thornton, owner of Artisan Fidelity, for the unit cost of 1 to 5 platters for both stainless steel and copper before I placed my order last year. The price break per platter for 3 or more platters is necessary to bring unit cost down to a reasonable level. For 3 or more platters the cost for copper is about $350 more than SS per platter. No mixing SS & Cu. to get a better unit cost.

For my order of 4 platters (3 SS & 1 Cu.) the unit cost for SS was at the 3 platter rate, and unit cost for copper was at the 1 platter rate. That made the single copper platter much more expensive than the additional amount per platter for copper noted above.

What are the rough prices per platter that you paid in the end you can also PM me?

I am busy here in the Netherlands to check if someone can make a copy of the original platter in Copper or Brass.

Anyone know what the mix combination is of the Copper version is like or is it 100% or a mix with Zinc?

The stainless platters from Artisan Fidelity were fabricated from 316 stainless steel, and the copper platter from pure copper. I'll send you a PM with per unit costs.

Could you send me a PM as well? I'm also curious to know.

Sure, PM sent.

Mark B thanks for the information i have someone who can build for me an copper platter and he can use my original platter as base. He is a skilled turntable builder that makes it easier to communicate.

 

[Plato65]

And what does he charge and is he willing to consider doing more, if I may ask?

 

[Plato65]

I haven't tried that tonearm, but that Mitchaku headshell is a personal favorite as is the SaSuPa stylus cleaner.

Did someone say alternative to YSA-2?

That's a nice looking arm.

 

[Poorbeek]

I'd also add:

Who bears the cost when the aftermarket platter eventuates to be less than perfectly machined? Will the machinist back up their reputation?

My turntable has to go there first so he can investigate the motor and bearing assembly and the spindle. Then he also has my original platter.

He is an pro builder of turntables here is a link to his website: https://www.wilkingturntables.nl/

Offcourse there is an risk but with the original platter and turntable that is an minimal risk i think.

As Mark B mentioned earlier it is way cheaper to make more then 1 platter due to labour, etc!

Have we discussed these Yamaha studies of tonearm geometry before? Quite interesting:

"Regarding the tracking error distortion, according to the measured data, in YSA-2 , only the distortion of almost the same level as YSA-1 which suppressed the tracking error is generated on the outer circumference where the tracking error should have occurred as much as 10 °. You can see that it is not .
From the above data, it is shown that the tracking error, which was considered as a problem, was not a big problem in YSA-2."

In othe words, YSA-1 & YSA-2 produced the same distortion even if cartridge alignment was completely different => cartridge alignment doesn't really matter...

Very interesting link Theo and on further researching I found a page on the DIY Audio website where the very talented and highly regarded cartridge designer from Lyra (Spectral) Mr Jonathan Carr said some positive things about the pure straight tonearm. This is what he had to say.

"Two days ago I had the opportunity to participate in a listening session in which one of the variables was a pure straight arm (Fidelix 0 SideForce), along with a prototype version of the same design (with offset angle). The bearing is a unipivot with a hanging extension that stabilizes rocking tendencies in a manner similar to the Simon Yorke. Both tonearm versions use universal headshells, making it easy to compare them with the same cartridge.

I felt that the offset angle version was a little cleaner-sounding in the mid and upper frequencies, but lost out in a substantial way when it came to dynamic range, transient impact and pitch stability.

The designer agreed, and said that the listening results were why he never put the offset angle version into production (although that was his initial plan).

The cartridges used were a Fidelity Research FR-1 Mk2 (with elliptical stylus), and a JVC MC-L1000 (with Shibata stylus).

IMHO, it is worth listening to a pure straight tonearm such as the Viv Rigid Float, if for no other reason than to educate your ears regarding what having an offset angle does for the sound, and does to the sound."

Great link. Thanks Plato65

Very interesting! The moniker "berlinta" lower in the page is Frank Schröder, the well-known tonearm maker. He really seems to know what he is talking about, and not just in this comment.

Could I also get a PM regarding this subject Mark.

Thank you

Of course. PM sent.

I have a question is the spindel conical in size so the platter fits better?

View attachment 2012487

Yes it's conical with 1/10 relation between diameter/deepness of hole. This means the hole on top is 13.5mm and the platters thickness or holes deepness is 18mm which gives 0.1x18mm=1.8mm wider hole on the bottom side which equals to 13.5+1.8=15.4mm.

I have ordered an Holistic Audio 103C which is an upgrade DL-103 and an retipped Benz Micro Glider L2 which will be both fitted on an Jelco HS 25 headshell. Hope to have them in 2 or 3 weeks. Very very curious how they will sound.

 

[chobochobo]

That Benz looks like a hypodermic!

I had to lookup the word "hypodermic" but you are absolutely right
