Thanks Richard,
I think that makes sense....🤓

The Palladian-A step beyond
The new cartridge from Acoustical Systems may finally be the LOMC to fully realise the theoretical advantages of the genus.
And convince those long-suffering audiophiles to whom the 'modern' MC presentation has been anathema to 'live sound'....that the realism of vintage LOMCs like the SPUs and FR-7 series has finally been recaptured 👀

Halcro, Even if the movements on the stylus end are similar, I think we need to look at the stylus/cantilever as a system, a vibrator. That might sound funny, but that's exactly what it is. That little guy has to vibrate 20,000 times per second to achieve 20KHz. To think that some carts have response to three times that or more is hard to conceive, but it's true. Regards, |
Raul, Given your criteria for a great cart (sounding live), you might like the Acoustical Systems offerings? I try to keep an open mind, but like you, won't endorse something I haven't heard or jump on some bandwagon. Have you heard any of the other AS models? I have to withdraw my analysis of uni-din alignment, at least for now. I have reason to believe it might be based on false information - the 63.3 and 112.5mm nulls. More on this later. Regards, |
Dear @fleib : Here are the calculations to achieve those null points that every one can have and use in any tonearm: http://www.vinylengine.com/tonearm_alignment_calculator_pro.php?arm1=Arm+1&l1=el&a1lv=270&am... you can read the null points values in the number charts under Löfgren B status. @halcro there is the " invent " of your " friend " !!!!!!!!. As usual with: a fraud. Now, that you know how to do it you can play " inventing new " kind of alignments. Regards and enjoy the music, R. |
Not so fast Raul. Okay, here's the deal; I saw a PDF written by Dietrich Brakemeyer in 2015. It kind of explains the design criteria of uni din. It gives a brief history of alignments (I won't bore you with the details) and talks about his alternate alignment as an option. As a preface to the PDF he says the published nulls (Analog Planet) are wrong. I want to make this clear. I have not been in touch with Acoustical Systems or Brakemeier directly, or Fremer, and I have no vested interest in any of this. I saw this late at night and at first I thought perhaps the nulls change with eff length. After a second reading I'm not sure, but probably not. Check this out- to paraphrase: ** You may be tempted to recalculate Uni-Din based on the known second null point with the calculation tools offered in VE or similar websites. However, this inevitably leads to the first null point being more than 20mm away from reality, and thus leads to a curve that is anything but Uni Din.** I'll be honest. I don't know what the hell he's talking about because there's not enough info. I don't have an AS alignment device to debunk this. AFAIK this is like a Dennesen or Feikert protractor which gives you the inner null? One of these protractors automatically gives the outer null. If one null can not be calculated from the other, it can be measured. This requires a novel device called a ruler, or you could go to VE and download a Chpratz protractor which is just a calibrated straight line. Uni-Din owners - measure your nulls. |
