Apr 30, 2012	Technics SP-10 mkII speed adjustment question Dear Sarcher, If the CU180 weighs 4 lbs, I personally would to use it on a Mk2, as the stock mat weighs only about one lb. The whole platter weighs ca 8 lbs, I think. So by using the CU180, you increase the inertial mass by nearly 50%. But this is...
Apr 29, 2012	Who needs a MM cartridge type when we have MC? JCarr, Thank you for one of the most thoughtful and informative posts ever, among the 7000+ posts on this thread. I am going to copy and save it on my desktop for reference. When I qualified my perhaps ill-conceived hypothesis by admitting I have ...
Apr 28, 2012	Who needs a MM cartridge type when we have MC? Dover, Note use of the word "theory". In other words, I made an observation and I then have advanced a hypothesis to explain it. I just threw it out there. Also, it was very late at night when I wrote that, with kind of a snootful of booze on boar...
Apr 28, 2012	Technics SP-10 mkII speed adjustment question If EMI is a real problem, one could also make a shield expressly to treat that problem; the shield can be placed under one's mat of choice. I did exactly that for my Kenwood L07D, which uses a stainless steel platter mat, which you would think is ...
Apr 28, 2012	Who needs a MM cartridge type when we have MC? Henry, Sorry for my indiscretion. I am sure that the direction of the rotation of the water in your house, in sink or toilet, as it goes down the drain is politically correct. It's interesting to me now; for years I read the reviews of REG in TAS....
Apr 28, 2012	Who needs a MM cartridge type when we have MC? Timeltel, The SUT in the Allnic is built in to the MC inputs. You can't avoid it, if you want MC-type phono gain. He reported to me that the max net resistance that can be presented to an MC cartridge (and in this case to the Stanton) is 278 ohms....
Apr 28, 2012	Who needs a MM cartridge type when we have MC? I theorize that the sense of increased detail with LOMC cartridges is due to their lesser ability to re-create the harmonic envelope of a voice or instrument, compared to the best of the MM or MI types. Your comments fit with my notion, if you thi...
Apr 28, 2012	Which Mono Cartridge at around $1,300.00? Thanks, JCarr. I think it was I who conflated "Dorian Mono" with "Delos Mono", which may have created some confusion (at least in my own mind), or maybe it was my own wishful thinking that you would build a Delos Mono. Also, you confirmed what I a...
Apr 27, 2012	Who needs a MM cartridge type when we have MC? As far as I can find out, the AT630 gives "20db" of gain. This implies a turns ratio of 10:1, which means that if Timeltel has a 47K resistor at the input of his phono stage, the Pickering is seeing 470 ohms. It might well be that 470 ohms would s...
Apr 27, 2012	Which Mono Cartridge at around $1,300.00? Correction: Miyajima supplies a 3.0mil stylus for 78s, not 1.0mil. However, for some reason I seem to recall that there is a class of mono LP that plays best with a 1.0mil spherical tip (or "conical", as Miyajima describes it). There is more infor...
Apr 27, 2012	Which Mono Cartridge at around $1,300.00? What Pryso said. My predilection for the Miyajima is based on the clear statement on their website that the Premium is a "true" mono design. Added to that, as I understand it (could be wrong) the best stylus for original early to mid-50s mono LPs,...
Apr 27, 2012	Can I Degauss my vinyl ? Rodman, Thanks for the URL. Yet another, totally different, explanation for why one should demagnetize LPs.
Apr 27, 2012	Who needs a MM cartridge type when we have MC? Raul, Have you listened to your LZS with a 1000R load or higher? If not, then your opinion that it sounds "good" with a 100R load is neither here nor there. Further, what we need to know is the turns ratio of the AT630 and the resistance across it...
Apr 27, 2012	Which Mono Cartridge at around $1,300.00? "More expensive" than what? Compared to their stereo equivalents, e.g., a Lyra Delos vs a Lyra Delos Mono? Is the latter more costly? If so, I would guess that it's a matter of marketing and very low production numbers. If the Delos Mono is more c...
Apr 27, 2012	Which Mono Cartridge at around $1,300.00? Goofyfoot, Your rationale is as pointless as mine, so, go for it. I will say that I trust Syntax, since he is not one to say anything at all, unless it is from his personal experience and is strongly felt.By the way, I do not know why building a c...
