| antiskate disc Yogi, there are many factual errors in that video. Some are as follows: He says that early tonearms did not need AS because VTF was very high for early ceramic cartridges. Wrong. The friction force is directly proportional to VTF. So high VTF mea... | |
| They should charge more for it… I think Einstein was referring to a hypothesis, not to audio gear. A hypothesis should be as simple as possible to explain the data, but not simpler. The design concept of the GMT is reminiscent of an older very high end turntable that was made i... | |
| Opinions on a Grace F8c for a freshy Buy an F8 or F9 cheap and then send it to Sound Smith for their Ruby upgrade. The resulting cartridge will outperform many low to medium priced LOMC cartridges, which of course is a matter of my opinion. But my opinion is based on owning an SS u... | |
| antiskate disc The skating force exists because of friction between the stylus contact patches and the groove walls. Blank LPs don't have grooves, obviously. So a blank LP is not a really good model for creating a skating force and then correcting it with AS. ... | |
| antiskate disc Here’s what I do, and I don’t claim it’s the only way to end up with an effective amount of AS. (There is NO exact correct setting.) Play a stereo LP with music and set AS to zero. The result should be some audible distortion in the R channel. Now... | |
| Bi-amping McIntosh MC2120 and MC2125 with Klipsch RP-5 The possible advantage is eliminating the passive crossover network at the speaker but you have to replace it with an electronic crossover ahead of the amplifiers. Experimentation is required. | |
| They should charge more for it… I read the GMT white paper on the WB website. What they’ve done and the way they did it are impressive. I’m sure it’s superb. Whether it had to cost as much as it costs is a matter for someone else to decide. All manufactured products are about ma... | |
| They should charge more for it… I refrain from mocking equipment based on pricing alone, but one has to realize that the guy who spends the big bucks will always be limited by the quality of new and used LPs he must play on it. He’ll need a good imagination to even dream he’s he... | |
| Analog Magic Question Ironically, the way we vinylphiles use the term”zenith” doesn’t conform to any conventional definition of the term. | |
| 2020 update : JC Verdier La Platine thekong, If the "motor unit is transmitting vibration to the platter", then I would replace that motor. Admittedly, there is no motor with zero vibration, especially as the load is perpendicular to the drive shaft; it's a matter of degree. Any mot... | |
| Luxman PD121A - PD441 What Dover said, but I do think there is a single tonearm variant of the PD441; I don't know the alphanumeric designation for it, but it might be a bit cheaper if you can find one. In fact, if you can find either the PD441 or the single tonearm v... | |
| 2020 update : JC Verdier La Platine Theory says you want the motor and the chassis to react ideally in the exact same way to external disturbances, so as to maintain stable belt tension at all times. That helps optimize speed constancy. Therefore theory says don’t put isodamp under ... | |
| Analog Magic Question "In theory it should if the effective mass is low enough to render the resonance frequency of the combination using an LVB is in the 8-12 db range in both planes." As I am sure you know, frequency is measured in Hz, not in db. So it might seem yo... | |
| Garrard 301 - Project How does Analog Magik measure “distortion”? And what kind of distortion does it measure? Thx. | |
| In need of a GOOD 3:1/4:1 passive input selector I see now that your Bryston 1B-MC is a preamplifier. Up until now, I thought it was a power amplifier. My bad. So as I now understand it, you feed your passive switch with each of your 2, 3, or 4 turntables, Then the output of the passive switc... |
