Tonearm recommendation

Hello all,
Recently procured a Feickert Blackbird w/ the Jelco 12 inch tonearm.
The table is really good, and its a keeper. The Jelco is also very good, but not as good as my Fidelity Research FR66s. So the Jelco will eventually hit Ebay, and the question remains do I keep the FR66s or sell that and buy something modern in the 5-6 K range. My only point of reference is my old JMW-10 on my Aries MK1, so I don't know how the FR66s would compare to a modern arm. So I'd like to rely on the collective knowledge and experience of this group for a recommendation.

Keep the FR66s, or go modern in the 5-6K range, say a Moerch DP8 or maybe an SME.

Any and all thoughts and opinions are of course much appreciated.

Cheers,      Crazy Bill

dover, no I don’t modified my 505 and the new set up is only 2mm ( around it ) on P2S and less than 1.5° on OA. The dyna specs are not accurate.
Never mind, has no critical importance your posts but a misunderstanding by your part. Please don’t give any answer to this opinion.

Raul,
Accuracy of set up is critical to optimising the performance of an analogue playback system.
You are wrong when you make a contention that alignment choice - Baerwald, Lofgren, Stevenson etc - is of less importance. This shows a complete ignorance of the underlying engineering principles and choices that designers have employed in the design of their tonearms.
If you think that aligning a cartridge in such a way that the cartridge is out of alignment with the vertical bearings has zero impact, then this reinforces to me that you do not understand basic mechanical engineering and basic principles of physics.
If you don’t want responses to your posts then you should not be participating in this forum. I suggest you start another website where you can peddle your theories without being interrupted by others who may know more than you.

Pryso, Dennesen sold a separate device for dealers. I couldn't remember the name. I searched for a photo, but couldn't find one. It was called the Pivotram and used for locating arm mount holes.  I do the same thing as you - reverse the SoundTractor bar and use a ruler to measure distance. It's easy for me to correct for the offset of the bar and get a pretty accurate mount hole. There is usually a little play in the fit of the arm pillar into the hole, especially with DIY drilling.

When using a pivot pointer device like this to align, it doesn't matter if your mounting distance is off a hair or two, as long as you can align to the grid with the pointer in correct position, your alignment is good. A SoundTractor or Feikert works where the pivot is actually located, not where it theoretically should be. If your arm mounting distance is off a bit , and you get a good alignment, then your offset angle will also be off a hair.  Here's an old discussion about it. My user name was lfleib.

With most pivoting arms the cantilever is not pointing to a pivot, due to offset. The discussion of maintaining mfg. offset is arm specific, and should be limited to that IMO.

RE: the quote - I tend to think the Brits should be blamed for most things, but I don't know about the Japanese use of the Stevenson alignment. That seems a bit of a stretch. The use of Stevenson was a very sensible thing at the time, but became a sort of default standard along with 15mm overhang.  If you have an arm designed for Stevenson, there are some options.

Part of the quote was linking Dynavector to Stevenson.  It is not.
