| Albert Porters after market panzerholz plinths Dear Albert, Now that you may be lurking here for a moment, can you say what mat you are using on the Mk3? Someone said "copper" but now which copper mat. As you know, there are several in the marketplace. Also, it would be interesting to know wha... | |
| XV-1S and Antiskate Doug, Thanks for the explanation, but by that loose definition, what is NOT a gain block? Only straight wire, most likely. But then, wire also affects sound. In the parlance I am used to, the term "gain block" would be interchangeable with "gain s... | |
| Who needs a MM cartridge type when we have MC? Dear Ecir, For capacitance values in the picofarad range, you don't have much choice in terms of materials, but silver mica or polystyrene are the best available and are both good sounding. M Percy has all the polystyrenes you may need. Don't real... | |
| XV-1S and Antiskate I agree with Doug that the grooveless LP is useless for setting anti-skate, but apart from that, lets admit that skating force is a result of the offset angle of the headshell on a pivoted tonearm plus the frictional forces generated as a stylus t... | |
| Who needs a MM cartridge type when we have MC? Wayne, I would say "no" to your question, if you want to make rules. As a rule, the need to match cartridge compliance with tonearm effective mass is still valid, but it is obvious from everyone's experience that there ARE other factors at play (e... | |
| Who needs a MM cartridge type when we have MC? Back in the old days, tonearm-makers did make it a point to brag about low friction bearings, just as cartridge makers used to enclose a frequency response graph along with each cartridge. | |
| Who needs a MM cartridge type when we have MC? Not to be a nitpicker, Raul, but the data you quote say "less than" 50mg for the bearing friction of a DV507. This means to me that there is some sample to sample variation but that the value is always "less than" 50mg. However, one hopes that is ... | |
| Who needs a MM cartridge type when we have MC? Dear Raul, In your remarks about bearing friction, I presume you refer to friction in the lateral plane. Yes? Of course for the DV tonearms, we have two different pivots, one for lateral and one for vertical. Does DV publish the figure you quoted ... | |
| Albert Porters after market panzerholz plinths Thanks, Mike, for the info on your "copper tops". We've discussed this before, and I should have remembered that those surfaces belong to the respective platters, not to any mat.Logenn, or anyone, as long as you have the correct adapter in place s... | |
| Albert Porters after market panzerholz plinths I use a SAEC SS300 metal mat on my Mk2 and Denon DP80. Weighs a bit over 1 lb and seems to be well tolerated in both cases.Mike, I presume Steve Dobbins made your beautiful copper mats. (Well, he surely made the one on The Beat.) Does he sell them... | |
| Albert Porters after market panzerholz plinths If the M-S mat weighs 4 lbs, consider that the platter + mat now weighs over 12 lbs. (If memory serves, the MK2 platter alone weighs about 8 lbs.) This represents a nearly 50% increase in mass over the stock platter + mat (8 to 9 lbs total). I'm j... | |
| Albert Porters after market panzerholz plinths What is the weight of a CU-180? The stock MK2 mat weighs a bit more than half a pound. I would not use a mat that weighs much more than 1.5 lbs. It is not the bearing I would worry about; it is the servo action. The servo and motor were designed t... | |
| Albert Porters after market panzerholz plinths Jfrech, Do you recall or can Albert tell us what turntable mat he is using on his Mk3? Surely the factory stock rubber mat can be beaten. The choice of a mat makes a huge difference, once the other elements are optimized.I like your choice of the ... | |
| Albert Porters after market panzerholz plinths Dear Halcro, Have not laid eyes on a live GPM, let alone heard one. Maybe I will see one at the RMAF, if I get there.Dear Dbcooper, I am constructing a combination baltic birch/slate plinth for my SP10 Mk3. Albert was kind enough to lend me his id... | |
| Albert Porters after market panzerholz plinths Wonder if you can cut it with a waterjet, a la slate.For comparison, a slab of Pennsylvania slate that is 12 inches square (one square foot) and one inch thick weighs 15 lbs. (Slate from other sources can be more or less dense. For example, Vermon... |
