FR66s vs Ikeda IT-407 CR tonearms


Has anyone compared the FR66s to the newer Ikeda IT-407 CR1 tonearm? Any thoughts? In previous years, the Ikeda was available with either copper or silver internal wiring but the recent models don't mention anything about the tonearm wiring. Can anyone comment what type of wiring is used in the latest editions? It would seem intuitive that the later Ikeda IT407 should be a better performer than the FR66s having improved material and bearings over the FR66s but the proof is in the hearing.

The FR-tonearms can only be perfectly aligned with the Dennesen Soundtracktor.
Try with any other alignment tool of today - no matter if Bearwald or not....... no matter if IEC standard - and it will result in a misaligned cartridge and too little overhang thus in a pretty bad tangential curve with the zero-error points being too close together.
Do align them with a Denessen Soundtraktor and precise - absolute precise spindle center to bearing center of 231.5 mm for the FR-64s and 295 mm for the FR-66s and you will get sonic results which will open up your ears and minds.

Dennesen is just a  predecessor of Dr. Feickert protractor ?
Or there is any fundamental differense between them? 

Here is an old review for Dennesen by B. V. Pisha (Source: Audio magazine, Mar. 1980)

Seems like Dr. Feickert is much better tool today. 



I wondered whether Syntax's post, from late 2014, was written before the advent of the UNItractor, designed and built by his colleague, Dertonearm.  The UNI and the even later SMARTractor are in a way a homage to the Dennesen, so I was surprised that he did not mention even the UNI in his post about alignment.  That said, I own a UNI (and an original all-metal Dennesen).  It seems to me that I purchased the UNI prior to 2014, which means that it must have been on sale when Syntax posted in October, 2014.

After mounting the FR64S using the Dertonearm-recommended 231.5mm for P2S, I aligned it using the UNI.  I am very happy with the FR64S, and Raul has criticized me for liking it.  I guess that is a sort of badge of honor.  I have mounted an Acutex LPM320STRIII induced magnet cartridge on the FR64S, albeit using a Dynavector headshell which is much lighter than any of the heavy FR headshells, but still not really "light" as headshells go.  But still, this combo should not work well, because the compliance of the Acutex is given as 42!!!  Nevertheless, it does work very well; it's just a pleasure to listen to this combo, mounted on my TT101.  We just got home from Tokyo, where I purchased several headshells, including a Yamamoto carbon fiber job, based on Halcro's recommendation. I plan to try the Acutex on the Yam headshell, at some point. 

Does anyone have any idea why the FR64S seems in this case to be exempt from the "rule" that governs matching cartridge compliance to effective mass?  My hypothesis is that over the years, the compliance of my Acutex (which I purchased NOS) has gone down due to stiffening of the suspension, while the effective mass of the FR64S is less than typical due to using the lighter DV headshell.

The general statement made by Gordon Holt which is

quoted by Syntax can be made even ''more general'':

''devaluation as function of time''. This mean more than only

monetary devaluation.

I mentioned earlier the German Magazin ''Das Ohr'' in which

both the FR-64 S and FR-64 FX are reviewed (1984).

The German importer was also allowed to comment on

the reviews. His advice was to buy FR-66 because those

will be in short supply and explained that the cost of their

production are such that the arm can't be sold for a

'reasonable price''. That is why the FX  is produced from

aluminum. The curious fact is that the same happened with

SME 3012 , 3009. Their first version were made from steel

the following from aluminum. While without anti-skate

provision those steel versions are much more expensive

and rare.

Impressed by J. Carr's authority and knowledge I purchased

Ikeda 345 ''the best ever made according to Ikeda'' according

to Carr. I just sold the 345 but still keep my two FR-64 S

and use the silver variation in one of my systems.

To me the FR-64 S is better made and much more easy to

use. The anti-skate provision by 345 is an enigma. But

consistent with my ''general theory'' I just purchased the

''older'' IT 245 about which very little is known.  This is the

first arm made by Ikeda's own company after the FR- kinds.

I hope to inform the members as soon as I get and test

this arm.



Wow, this old thread that I started has come alive again after almost 4 years. Here's my update:
I now have 2 FR66s tonearms and they're still the best ones in my inventory. One thing I would like to pass on to others who may be interested is that Ikeda can service (clean and oil the bearings, replace broken connectors at the tonearm and base) and also rewire FR64 and FR66. I've had one FR66s serviced and rewired and I'm very happy with the results from Ikeda. Another point I want to share is that I had the chance to compare one FR66s with original silver wiring with another FR66s with rewiring done by Dertonarm on same turntable and same cartridge. The rewired FR66s was clearly better which lead me to rewire the original FR66s at Ikeda. FWIW.
