| Vintage DD turntables. Are we living dangerously? *since the availability of the Feikert Speed App I have regularly stated that the Data downloaded on its 'Chart Info' was imprecise and non-scientific as it was not possible to duplicate the results from test to test.*Why do we give credence to th... | |
| Interesting project started by Michael Fremer *can anyone tell the difference ? Thats the Question*To tell or not to tell, that is the question? Whether 'tis Nobler in the mind to suffer the Slings and Arrows of outrageous analog, or to take arms against a sea of quantifying troubles. (Hamlet... | |
| Pani ... New ART-9 up and running ... ART 7 is available through Amazon from Japanese sellers. You might have to look in musical instruments or do a general search.Optimal MC load is preamp specific. The extra capacitance acts as a low pass filter for the RF type noise. | |
| Vintage DD turntables. Are we living dangerously? Halcro,I don't know what test record you're using, but this software, app, or whatever, is giving an erroneous impression. The TT101 has W/F 0.02% WRMS, and speed deviation of zero w/up to 120g VTF. That W/F is at the limit of conventional testing... | |
| Vintage DD turntables. Are we living dangerously? Taking a break from applied technology, how about remedial physics?What do MPH and RPM have in common? Time is a dimension we have divided precisely, based upon, but not dependent upon, the movement of Earth around the Sun. Our division of time do... | |
| Vintage DD turntables. Are we living dangerously? I wonder how accurate this is. The waveform peaks at +16Hz and bottoms at -20Hz. That's a spread of 36Hz, a little more than 1%. A scope or a meter with a frequency counter could be used to check results. Another fly in the ointment - Werner Ogrie... | |
| Vintage DD turntables. Are we living dangerously? RK,"Look at the raw trace for the WE8000.Start at the first lower min freq, just above 3130 hz. Other than the max at around 3164hz, count every sharp change in direction until immediately before the next min of around 3130 hz again.I count 14. Th... | |
| Vintage DD turntables. Are we living dangerously? Dover,"Speed is never absolute. It is always measured from a point of reference. The planet is rotating, the measured speed on your platter is relative to the rotation of the planet - it cannot be absolute."We're talking rotational speed not land/... | |
| Vintage DD turntables. Are we living dangerously? RK,Just as I thought. Thigpen says, "Since the advent of the belt drive turntable, wow and flutter has been purely a function of tonearm geometry, the phono cartridge compliance with the elastomeric damping, and surface irregularities in the LP."H... | |
| Vintage DD turntables. Are we living dangerously? Dover,"There is no such thing as absolute speed. Speed is relative."That is incorrect. For a turntable, 33 1/3, 45 RPM is absolutely the correct speed.How it's measured is another story."The timeline only measures the arrival of a single point on ... | |
| Vintage DD turntables. Are we living dangerously? Richardkrebs, The measured performance is inferior to actual performance?Wow and flutter can only be measured with an arm/cart. Timeline measures or illustrates absolute speed. Henry has shown that absolute speed doesn't deviate when using 3 arms ... | |
| Vintage DD turntables. Are we living dangerously? Henry,"How does the cartridge know the mass of the platter....❓👀"You mean "know" in the biblical sense? When cart suspension collapses? I think you would agree that platter and mat, supporting surface, does make a difference. Some platters are des... | |
| Vintage DD turntables. Are we living dangerously? Griff,I don't usually speak against VPI, but their answer to your inquiry, "I was told by a return email that they no longer provide arm boards for the Aries", doesn't seem open to future possibilities. Perhaps their answer was worded differently,... | |
| Vintage DD turntables. Are we living dangerously? Halcro,I told you where I read that stuff and asked if it was correct. You don't seem too sure about all the additional complexity you talked about. It's all from the speed control adjustments and breaking? As far as platter weight you said, "This... | |
| Vintage DD turntables. Are we living dangerously? Griff,That's beyond belief. VPI still has Aries listed as a current table. Even if it were discontinued you should still be able to get an armboard. Have they no shame? I suspect they've grown too fast and forgotten where they came from. They used... |
