Anyone try the replica B-60 Fidelity Research VTA?


My sammle moved not only up an down but also sidewards.
The reason as far as I can judge is the pin on the screw
which connect the inner and the outer collar. The inner collar
slides along this pin up and down but if there is
any play between this pin and the notch of the inner collar
the tonearm will move also sidewards. This means that the
'replica' is not as 'exact' as claimed by the producer.
I assume that this screw is better made by the orginal B-60 .

Lewm - I had a spring cleanout of surplus gear about 18 months ago. At the time I had sitting in the cupboard unused - Garrard 301/401, couple of Rowland amps, Quicksilvers, Dynaco Mk3's, various preamps and a pile of other stuff. I was also sitting on a Klyne system 7 phono, Exposure phono in addition to the other stuff.
I also had the following arms - Eminent Technology ET2, Naim Aro, FR64S ( with original B60 ), FR64S, Helius Cyalene, Helius Omega & Hadcock ( and a couple of vintage SME's 3009/3012 ).
Cartridges owned at that time Ikeda Kiwame, Dynavector Nova 13D, Koetsu Black Goldline, Denon 103D, Fidelity Research FR1mk3, Shure V15vxmr, Shure V15vmr.

When the Dyavector Nova 13D came back from Dynavector ( they rebuilt it for me ) I decided to test all my phono gear and arm/cartridge combinations.

In terms of phono stages both my tube Marantz 7's ( 1 std and 1 heavily modified ) and Theta B Revised blew away the Klyne & Exposure so the Klyne and Exposure were sold off along with the Rowlands, Quicksilvers, Garrard 301/401 and other surplus gear..

I then tried the Dynavector Nova 13D, Koetsu Black & FR1mk3 on the Naim Aro, FR64 & Dynavector 501 arms - all mounted on the Final Audio VTT1.

Koetsu Black - on the Aro the sound is quick and lucid but fragile on piano. I do not think the Koetsu is a good match for the Aro, despite being Martin Collins reference for a number of years. On the Dynavector - less information, forshortened soundstage, very good lateral precision within the forshortened soundstage. Not as transparent as the unipivot Naim Aro. On the FR64, this is much closer to the Aro in speed and transparency, and the fragility on solo piano/guitar etc disappears. A more stable sound.

Dynavector Nova 13D - on the Aro - easily the best, fast lucid, transparent and excellent timing, this combo will track severe warps without missing a beat - it is very stable. With the FR64 & Dynavector the same differences as with the Koetsu - the FR64 resolves more than the Dynavector, presents a much more accurate soundstage, the Dynavector forshortens stage depth.

Fidelity Research FR1mk3 - very good on Naim Aro, ok on FR64, less than average on Dynavector 501.

Lewm, I do agree arm/cartridge combos are critical. For example I still think the best arm for the Koetsu Black was my old Zeta ( after I had the bearings replaced ). In terms of the stone bodied Koetsu's ( Onyx Gold vdh ) the Sumiko The Arm is the best combo I've heard. The Koetsu Reds are more variable, but I had excellent results with an Alphason/Koetsu Rosewood.
However, the general outcome of more speed and transparency on the Aro than the FR64 is consistent across all cartridges. Similarly the lack of transparency as regards the correct presentation of soundstage of the 501 compared to the FR64 is consistent with all cartridges.

From using the ET2 for 30 years with much experimentation on mass, electromagentic damping & decoupling of the counterweights, my gut feel is the Dynavectors electromagnetic damping is too severe and is killing the arms potential.

In general terms the Dynavector Nova 13 has considerably more resolution than any of the other cartridges except for the Ikeda. At present I am running it straight into my Marantz 7 tube preamp @ 47k - no step up required, the Marantz has plenty of gain for LOMC's, even the low output Dynavector. Step up devices I have to hand, but not used, are various vintage transformers including Altec 4629, Music Ref tube head amp modified, Blue Audio Systems solid state head amp ( built by Reto Andreoli of Magic Diamond cartridges ). Rest of system is power amp by Richard Brown and Tannoy Monitor Golds with my own crossover, all wired with MIT - Oracle power & interconnect cabling, original double shotgun 750 for speaker cable.

Dear Syntax, That is why I love my German group. They
always agree with me. There is, alas, no such thing
as the category 'wanted stuff' on our A'gon market.
So I was forced to use the 'selling category' as if my
intention was to sell the original B-60. There were
more as 250 viewers in the first day of my 'listing'.
There are more as 13 days since and I got not one single
offer. If you had not mentioned your anticipated price
I would write an very charming and polite email to you
but for this kind of money I can get the new Ikeda B-60.
I hope that my naming J. Carr next to Aristiteles may
have some influence on his reaction to my request to sell
to me the 'old-fashioned made' B-60 which he still owns.
Dover,
That's a very interesting summary, and you certainly do have a lot of listening experience that enables you to speak with authority on the products you've listed, or at least it qualifies you to have an opinion. Did you sell the Klyne 7 phono? (I'd be interested, maybe.)

Your choice of the Marantz 7C "uber alles" is a big surprise to me. Has yours been modified/upgraded/etc? It almost certainly cannot be all original, since any electrolytic capacitor made in the 1950s or 1960s is dead by now. Also, the germanium diodes used at that time are probably kaput. It's been decades since I owned a 7C, probably pre-dating the hegemony of MC cartridges, so I cannot recall whether it would have had sufficient gain for a true LOMC, but has yours been modified for more gain than original? The 7C was a wonderful piece of gear that I often regret selling, not because its sound quality was transcendent but because of its historical significance and the perfection of its design, the same reason I have kept my Leica M3 and its lenses. (Same reason I should never have sold my Porsche 550RS Spyder.)

Nikola, As I think I said by private email, I don't have issues with my faux B60, yet. There is no horizontal "play" in the mechanism. I agree the lubricant used is annoyingly "sticky", but I will leave it alone. It's really a simple device, and even the reproduction is overbuilt compared to some other devices that accomplish the same end for other tonearms.
Dover, you wrote that the Marantz 7 tube preamp @47k has plenty of gain for LOMC's.
Are you referring to the heavily modified one or stock
The load resistor might affect frequency response but not gain. However, I too am wondering about Dover's claim that his 7C has adequate gain for "any" LOMC cartridge. I tend to think his unit must be modified, but he will tell us.
