"Analogluvr- The one upgrade I would not do without is the flywheel, whether you have one or two motors. "What was the biggest improvement you perceived when using a flywheel?

+1 stringreen!I would add that another problem is some people can’t debate issues using facts and data, so they try to impugn someone’s character with innuendo: Others have other goals. and try to make their point with straw-man arguments: You’r...

When phoenixengr asked how I made my measurements, I responded and the answer is above. But when asked how he substantiates his claim that " Belt creep does exist and it is measurable," he becomes argumentative. Of course, he’s trying to sell some...

You’ve claimed that " belt creep does exist and it is measurable." That’s another rather odd claim. How have you measured this phenomenon? Are you denying that belt creep exists? That’s not only an odd claim, it’s counterfactual. Without belt cree...

It certainly is not an issue with my VPI and, yes, I’ve measured it. May I ask what you used to measured it? My VPI table changes speed considerably from cold to warm and so does every belt drive table I’ve measured. If you have the first belt dri...

To me a a constant stable speed is always better than a changing one. Agreed.  But constant motor speed does not equal constant platter speed, it's basic physics.  Belt creep does exist and it is measurable.  With an elastic drive belt, it cann...

The Phoenix does no AC regeneration, or lower the motor voltage after startup like the SDS. More noise. This of course is also incorrect. The Falcon/Eagle are AC regenerative power supplies and they use DDS technology to create AC regeneration wh...

SDS is better as once you set a speed it is locked to that. Phoenix corrects speed so it would be constantly changing which could be audible. This is a common misconception and is actual the opposite of reality. The SDS does not change its output ...

Can you clarify: display flashes?  Does it display 5 dashes or an RPM reading?   You can put the display to "sleep" with a long press of the on/off button (back panel) or it should blank ~ 5 minutes after the platter stops rotating.  Sometimes, su...

sbank is correct, the hum is cause by a grounding issue.  The Eagle PSU uses a switch-mode power supply so the 3rd wire on the AC output is isolated from the wall socket ground. If you are using a step up xfmr, ensure that the table's audio ground...
