Maybe a question is, how is the sound so good if the speed accuracy is not absolutely perfect. Or is it and the test is wrong.
Some people prefer the sound of SET with 0.5% distortion. What's your point? My post was not about opinions it was about facts, measurements and published specs.
Maybe I missed it, but what do we know about the methodology of the test. He measured off the encoder? What does this mean. Did he measure at the platter surface with a stand alone calibrated device?
The encoder is solidly coupled to the platter and provides feedback to the controller. It is the most reliable indication of the platter's actual motion that exists. It does not suffer from eccentricity or other defects like an LP that might adversely affect the outcome.
What if it was there to have the speed controller repaired?
It wasn't.
No.
He's using numbers obtained during a test via a process and variables that might influence the outcome.
So you have no idea what an encoder is or how closed loop feedback systems work but you can make wild claims and speculate that something wasn't right. Who's agitating the members now?
What we know is he doesn't like the type motor used on the table ...
Actually, I like the motor; I use AA motors on belt drive tables, it's just the wrong choice for DD.
...and is saying during a static bench top test of that type of motor with no load attached, it will behave a certain way.
Wrong, the platter was attached (see above).
That is not how an assembly of parts ultimatly behaves.
Wrong.
Maybe the platter smooths out anomalies in the motor and provide a more precise speed.
It does, but only to a certain degree and in this case, not enough.
Maybe that topology of motor has better Torque. Maybe it has less noise or easier to mitigate noise. Maybe supports a platter better. It may have some other attributes that brings the whole of the table to a higher level when its utilized in a final assembly.
Maybe you have no clue what you are talking about and are asking a bunch of really stupid questions in an effort to agitate the members. (Personal comment removed).
ran slightly high at 1389.2Hz (+0.0224%), a long way from 1PPM.
The speed stability was quite poor actually
Comments as such open a can of worms and get people agitated at each other.
Kind of like this post by you after Christan's call for civility. Your lack of self awareness is astounding.
Maybe Phoenix owes a word to readers for somewhat misleading them on the whole of what transpired. I see a guy who lit a fire, deleted his words and ran.
Sorta like what you just did (posted, deleted, ran)?
OK, here's my message. I posted my findings after reading a completely ridiculous and over the top review that I felt was in gross error. To date, nobody has offered any evidence of misleading or false data, only speculation and conspiracy theories. My post understandably complicated the relationship between Ed and Christan and I was asked to take it down. When I obliged and asked the admins to delete the content (3x) they refused. They said they couldn't delete other poster's content because those other posters hadn't violated any TOS (fair enough) but they also refused to delete my posts at my request (3x). They did however remove an entire thread in Aug 2020 that was critical of VPI at the OP's request, including my posts and posts by dozens of other members who had not violated any TOS. Without warning or notification. Go figure. I deleted my posts in the current thread myself.
FYI: CGI is not a repair shop (they are a mfr), neither CGI nor Ed are my client (my work was done independently and at no charge) and there were no NDAs in place either implied or explicit between Ed, CGI or myself.
Mike L. spoke with Ed and receive a partial understanding of the situation. Mike then spoke with Ron who encouraged him to post an inflammatory message that IMO misrepresented the situation and started the ensuing mess. I was asked, and thought it best, to stay out of the fray as any further discussion would most likely only make things worse. With the exception of a few posters, what ensued was a embarrassing display by a bunch of adolescent chicks on the rag posing as old men. You should all be ashamed of yourselves. I'm ashamed of all you and for you. I'm also done posting on and visiting this site. I'm embarrassed to have been a member here. Please close my account.
