Best cartridge for very old worn vinyl
Howard, there are some heated discussions about alignment on this forum, so I understand your reluctance to go there. I’ll probably get grilled for saying this (or accused of having tin ears) but to me the supposed sonic differences between the different alignments (Löfgren, Berwald, Stevenson) are strongly exaggerated. Many tonearm manufacturers used proprietary alignments different to the established ones mentioned above, so apparently I'm not the only one. The ’experts’ have a preference for Berward and dismiss everything else as inferior. Yet Ikeda chose Stevenson for the FR64/66, so if you use the P2S specified by FR you get that alignment and the FR7’s (and SPU’s) hit all three ’bullseye points’ on the Feickert. That’s good enough for me, as I use several FR7’s and SPU’s. So I adjusted the overhang on all other cartridges in accordance to this alignment, which delivers excellent results. I did try the P2S distance favoured by these experts to adjust it to Berwald and made comparisons with the Stevenson with several cartridges, but the difference to me is negligable. If anything I prefer Stevenson, because it theoretically has the lowest distortion in the inner grooves. I happen to like orchestral music and these composer guys usually like to go out with a bang. I like to entertain the thought that Ikeda must have been a Wagnerite..... I assume that ’turning’ the top plate of the Brinkmann pod shouldn’t be too difficult, but there’s no guarantee you will get the correct P2S distance for the FR66. We must assume the dealer knew what he was doing and tried that. But perhaps you should give it another try, good luck! |
@edgewear thanks for that ! I spoke with dealer and figured out how to move the arm on the Brinkman so hopefully will manage it in the next day or so. Not being technically savvy I don’t profess to understand any of the physics at all... The Brinkman alignment tool is based on the Dennesen alignment (?) All you do is fit it over the spindle, get one end lined up over the middle of the tonearm pivot and when all that’s in place you adjust the cartridge so that the tip of the stylus is in a small hole on the Brinman alignment tool. On that basis presumably the s2p doesn’t matter so much as long as you can adjust the cartridge in the headshell so it lines up on the small hole on the tool ? Where I guess it might matter is if you can’t adjust the cartridge (like in SPU /FR7) ? Again I’ve no idea what I’m actually talking about here, but if I’m able to adjust the FR 66 on the Brinkman that the FR7 is aligned properly on the Brinkman alignment tool, then presumably that’s job done ? At that point does that also mean that the p2s distance will be “correct” ? if the answer to that is ”no” then it begs the question whether something like the Brinkman alignment tool actually aligns cartridges properly or whether ( if it does) whether the s2p is a critical factor ? |
With same PS distance you can use 3 different alignmet methods by moving/twisting a cartridge in the headshell slots. Feickert protractor will give you Stevenson, Baerwald or Loefgren. Read more here. With FR7 series or SPU you have to stick to the manufacturer’s method, for IKEDA it is Stevenson, you can’t twist your cartridge, because they are headshell integrated models, so any other alignment will be wrong for those types (headshell integrated models). Some protractors are made only for one specific tonearm and you can’t use them for any other tonearm. Feickert designed for any tonearm, you can use it on any turntable and any tonearm and it's up to you which alignment method you want to use (Stevenson, Baerwald or Lofgren). The Dennesen is a protractor, not alignment, the alignment is Baerwald Denessen U.S.patent number 4,295,277 cites Baerwald (not Stevenson) |
