| SL-1200G/Hana ML Best Headshell Should have noted that when you multiply effective mass times compliance and take the square root, keeping compliance constant, then the ratio of the result with a 9g vs 12g effective mass is even less different than the square roots of the two nu... | |
| SL-1200G/Hana ML Best Headshell Think of it this way: square root of 9 is 3. Square root of 12 is ~3.4. So the difference between 9g and 12g is not going to affect the calculation of Fr by much. | |
| Analog Upgrade itch The Steelhead is compromised by its own very mediocre output coupling capacitors. And if you use it as a full function preamplifier, then the signal has to traverse two of those same mediocre capacitors. Upgrade the capacitors, then you've got s... | |
| Yamaha GT 2000 with 40 pound copper platter. Less rotational inertia, which is the main point of the high mass. But sure, it would “work”. Lower inertia would make it easier in the motor. | |
| Direct Drive Ketchup, I take the bearing as a given for any turntable of any type. So there is no special problem of a bearing in a DD type. All platters ride on some sort of bearing. Mijostyn, I don't know precisely how a Cosmos is constructed, but I do kn... | |
| Direct Drive Whatever Harry Weisfeld wrote on Audiokarma, it cannot be accessed unless one is registered over there. Sunnydas1, what is your point? In a direct drive turntable, you can think of the platter as the rotor part of a typical motor. As in a classi... | |
| SL-1200G/Hana ML Best Headshell If you look at the math, there is really quite a bit of leeway in effective mass and compliance that will give you a resonant frequency that falls within the typical range of 8 to 12Hz. And anyone who has done vinyl for a long time with a variety... | |
| Direct Drive I owe Mijo an apology. He referenced the STST because it is DD (and apparently suspended). So he was not being disloyal to his favorite suspended BD turntables, SOTA or Helix. | |
| SL-1200G/Hana ML Best Headshell Don’t bother. The titanium headshell is probably too heavy, if it really weighs 19 g or more. I’m not sure you would benefit even from changing the original headshell, but if you feel like experimenting, I would go with the carbon fiber headshell ... | |
| Direct Drive Mijostyn, Have you fallen out of love with the Dohmann Helix? Also, you can add a Herzan or Minus K shelf to any non-suspended turntable and be better off than with any spring-suspended turntable, BD or not, because all spring-suspended BD turntab... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? Indeed, if the 33 ohm resistor was in series between the IEC and the ground lug, on the one hand, and the PCB ground, leaving everything but the PCB containing the audio circuit at earth ground, that would be OK. But I still don't think we've hit ... | |
| What should I expect moving from MM to MC? Zarzu, you say MC cartridges are”faster” because they have lower moving mass with the “same suspension “. Yes, MC cartridges tend to have less moving mass compared to MM cartridges, but no, the suspensions are not the same. MM cartridges tend to ... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? Ok. My idea that floating the ground lug above ground along with the audio circuit is unconventional at best, based on what Atma wrote and my own measurements of two phono stages at my house. So I expect the ground lug on the EAR is in contact wit... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? So that 33 ohm resistor we see in the photo, which is in series between the threaded screw and the 3rd pin of the IEC, according to the OP, is either doing nothing or the chassis is floated by the 33 ohm resistor which I certainly agree is not the... | |
| What should I expect moving from MM to MC? “Dangerous, misleading, and wrong-headed” You got that right. |
