$12K Laser turntable vs $12k hi-fi turntable?
Mitch, From the tenor of your post, it would appear that you think there are a whole class of laser turntables. Not so. There is ELP and only ELP, as far as I know. Given the cost ($12K must be for their low end model; the top line one costs much ... 
Adjusting SRA using macro lens vs microscope
Doug, The Ortofon M20FL Super and the Azden P50VL (or something like that) are much improved with a bit of positive VTA. Also, back in the day I recall that my Grado TLZ also seemed to prefer slight positive VTA. (Paradoxically the bass response i... 
Adjusting SRA using macro lens vs microscope
Doug and anyone else who might know, do you think it was ever thus with cartridges? I mean to ask whether it has long been a custom in the industry to set the cantilever/stylus angle such that by leveling the top surface of the cartridge body with... 
Who needs a MM cartridge type when we have MC?
Dear Franklin, Do you know the phrase "garbage in/garbage out"? It means that the conclusions reached by computation are only as good as the input data. In this case, the data are not very good, so don't worry about it, and give it a try. As Raul ... 
2010 RMAF Analog Reports + Meet and Greet
I will be there, too. I am on a quest for high-ish efficiency, high-impedance full range speakers that can work well with my Atma-sphere amps and pose a challenge to my present Sound Lab M1s in terms of coherency and transparency. I hope to listen... 
Albert Porters after market panzerholz plinths
Dear Radicalsteve, 4.5 KILOGRAMS? Really? Holy patootie; that is 9.9 lbs, which is more than the platter weighs on a Mk2. How long does the table take to get up to speed, not that this alone is any measure of how the servo functions with such a hu... 
Albert Porters after market panzerholz plinths
Dear Albert, Thanks for the further clarification on which turntable gets the Micro mat. I fully agree that the Micro and the Mk3 would go well together. My reservations only relate to using the Micro with the much lighter and much less torque-y M... 
Albert Porters after market panzerholz plinths
Albert, Thanks for your response on mats. It is surprising that your favorite and second favorite mats are wildly different in material construction AND in weight. The Micro, according to others above, weighs ca 4 lbs and the Boston Audio Mat, whi... 
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 ...
