| Fidelity Research FR64s Headshell dilemma Dear @lbelchev : A tip for your calculations and with 245mm. on EL. At recorded LP surface 80mm. position the tracking distortion Löfgren B is 0.350% and Stevenson 0.735%. Difference: 0.385% higher on ST. At 90mm. is over 0.25%If you know what to ... | |
| Fidelity Research FR64s Headshell dilemma You have to made your home work. The data you posted are average or the maximum not at a specific groove position as my examples between Löfgren A and B. I know I can’t detect 0.09% or 0.13% differences in tracking distortions. I can detect a litt... | |
| Upgrade Dear @bms72 : Try the Analysis Plus Silver Oval speaker and IC cables, those are the ones I'm using in my system.I owned your 23.5 and even today very good amp and competitive with today designs.The unipivoth VPI change advise is a must to do it d... | |
| Fidelity Research FR64s Headshell dilemma So, there is no better cartridge/alignment geometry but we always listen differences when we make changes and those differences are present because the inaccuracies between the cartridge overall set up parameters at each alignment changes. Does no... | |
| Fidelity Research FR64s Headshell dilemma Dear friends: The whole cartridge/tonearm alignment subject is really important to understand it to stop that after market items follows taking advantage of our low level knowledge and I say that because that's exactly the history of after market ... | |
| Thinking about a Zesto Andros 1.2 to replace the John Curl PS in my Audible Illusions M3B Dear @mglik : Good that you followed the rigth @tooblue advise.Look, even with out the JC board the AI is better performer than the other one and you can know trhough its specs. The Zesto is really bad in the most important subject in any phono s... | |
| Fidelity Research FR64s Headshell dilemma Of course, no diagram/graphics in teh vinilengine calculator because the null points are inside the LP label not in the usable LP surface.R. | |
| How often to demagnetize mc cartridges? Dear @wcheng2 : I still have the same Sumiko you own. I used several years ago and in those old times I thought it makes that the cartridge recovery its " transparency " or something like that.I used till the fluxbusting damaged one of my cartridg... | |
| Fidelity Research FR64s Headshell dilemma Using other calculator it confirms that SAEC made it a " deep " manipulation with the must inner/outer groove radius.In this other calculator I used 37.4mm and 66.9mm and the off set angle and overhang coincide with SAEC specs.So manipulations/com... | |
| Fidelity Research FR64s Headshell dilemma Dear @bukanona : please correct me if I’m wrong. I just finished to analize what SAEC did it for the cartridge/tonearm alignment on each of his models and I took as an example your 308SX.Thank’s that you brought out here the SAEC tonearm alignment... | |
| Fidelity Research FR64s Headshell dilemma Other often " trouble " is that tonearm manufacturers sometimes like to " round off " the values, example: if the off set angle real value is 15.22° they just round and use 15° and same thing could happens with overhang too. The FR/Ikeda analized ... | |
| Fidelity Research FR64s Headshell dilemma Dear @nandric : """ What Kessler and Pisha discovered is that by te most tonearms the offset angle and overhang were wrongly chosen...""for me that only speaks that not all tonearm manufacturers took with the necessary professional attitude th... | |
| Fidelity Research FR64s Headshell dilemma Dear @bukanona : I owned SAEC tonearms and it’s a disaster for say the least. The only model with an orthodox alignment is the WE-8000 that I owned and that uses Löfgren B wiith JIS standard not IEC one. I have to say that the 8000 model was thenl... | |
| Fidelity Research FR64s Headshell dilemma @chakster : " This is how anyone can change alignment from Stevenson to Baerwald without changing PS distance...""yes, I’m not saying you can’t. The issue is that you are changing the EL with its implications and of course that with TT with integr... | |
