New aftermarket plinth for Technics SP 10 MK2/MK3/R from Acoustand

Well, if something to obvious we can't be aware of then obviously that something is wrong down . This is not in anyway an insult but only common sense.

Btw, this is what Jonathan Carr ( Lyra designer ) posted in this forum about those FR tonearms:

" I agree that the FR-66S would be somewhat better than the SAEC, but truth be told, I'm not overly enamoured of the "S" family either (and I say this as the long-time owner of a 64S with Elevation Base and Arm Stabilizer). The stainless steel is great to look at, but less great to listen to, and when I run mine I prefer to keep a compression wrap around the tube. "

That compression wrap is used to tame the developed resonances in the 64/66 tonearms.

He said too:

"  I've known Isamu Ikeda for many years,............... .....................................

And as Raoul suggested, I use the Warren Gehl armwrap, which is far more effective than heatshrink. It dampens the resonances of the armtube by compressing it radially, and works on a similar principle to how you play harmonics on a bass or guitar.

The armwrap's radial compression of the armtube makes the 64S and 66S operate a bit more like Ikeda's later arm designs like the IT-245 and IT-407, although these added interference damping by force-fitting multiple concentric tubes of various materials together.

FWIW, from the resonance-control point of view, Ikeda's personal favorite among his own designs is the IT-345, which I believe has a three-way concentric armtube structure. The person who's been building these arms for the past 20-odd years is of the same opinion.  "

That's why I posted what I posted.I know  perfectly what I'm talking about.

Please no bad feelings because what I posted had no intention in any way to insult you.

Btw, if some one knows about the 64/66 and any other analog subject is Mr. Carr. Don't you think?

Between other very special " toys "  JC owns this fabolous TT that in the picture has mounted the MAX 237 tonearm:

@rauliruegas 

You are living in the past. The Micro Seiki MAX 237 is not a great arm. One of its many failings is that like many vintage arms the vertical bearings are not offset to match the cartridge offset, which means that every time you adjust VTA the azimuth goes out. This is a fundamental flaw for me for a true reference system.

With regard to digital - what is your current reference.

Your opinion, good.

Dear @billstevenson   : This was posted by Jonathan Carr about that cartridge/tonearm resonance frequency:

" The match (or mis-match) between tonearm mass and cartridge not only affects the fundamental resonant frequency, it also changes the tracking performance. "
