Confessions from a VPI owner of some 30 years

I would like to start with a humble apology to the OP of a thread I recently (overtook) for personal reasons. smrex13, I apologize to you and hope your audio journey going forward is joyous!

To donvito101, I made my remarks personal and for this I apologize.

I checked for remarks from yesterday on the "VPI Prime noise issues" (2 threads, why, I don't know) . I still find it odd that VPI did not remark on smrex13' original thread, only to his last thread that ended, "not VPI's fault".

I've had a couple of issues since purchasing my VPI Classic 3 SE Sig. one year ago. I sent, (through my dealer), an initial question about the arm tower's operation on Feb 2016. I was told it would be forwarded to VPI. As of today, I've not received one comment.

I've recently, in the past 3 months, had a vibration issue through the 3D arm when the SDS is set at 33rpm. It is not noticeable at 45 rpm. I feel it through the finger lift.

I've tried oiling the motor, cleaning the belt & new talcum, the spindle bearing is just like recommended with the proper grease etc...

I relayed all of this through my dealer who asked for pictures and I sent them. This was two weeks ago. As of today, not one word. Because of my last question through my dealer in Feb w/ no response, I'm a little weary.

OK. So, my position is.... I should go through the proper channels. The dealer, right? VPI has their sales set up through a dealer network. This, I assume, is to take a burden off of them so they can be focused on manufacturing?

We/I/ you, pay a premium for this? I assume it's around 100% added to the actual cost of manufacturing. So, if I have an issue, I should follow the way VPI has their dealer network set up and take my concerns to the dealer. If this is not the way things should work, why then, doesn't VPI just sell directly? We/me/the end user could save BIG BUCKS.

That's pretty much the whole issue. I have no idea why VPI does not want to make any effort to settle this issue.

Cheers!

This will be my last post here.

@edwyun, If you read my post correctly, the ADS is not working fine. I posted that in the 33rpm mode when the adjustment knob was in it's center (neutral/VPI calibrated ) position, I had to turn it left...meaning it ran (fast) in it's factory calibrated setting. (Why is that so hard to comprehend?)

I've had one on one emails with Mat recently. He, (IMO) is not personally invested in the company. I really don't think he has a passion for music in general.

I told him that I will not call on his company in the future for anything. I hope he can realize his passion for teaching and transfer the operation of VPI to someone who has a passion for music.

I will never visit this site again.

Peace!

Finally, enough of the whining. Your ADS is working correctly. The ADS centre indentation represents 60hz, with your particular pulley, belt and platter combination, your table’s motor needs a frequency less than 60hz to achieve 33.333 rpm. That is the whole purpose of the ADS to allow each user to dial in the correct frequency to achieve 33.333 rpm. Time to move on!

I think this is well stated: Center detente REPRESENTS 60Hz;  it does not guarantee it.  The ADS uses an analog oscillator which (by design) has a very low Q tank circuit.  Low Q equates to poor frequency stability and any analog oscillator will exhibit worse performance than a crystal controlled circuit, by several orders of magnitude.  This isn't opinion or marketing fluff, it is verifiable science;  I've also observed this first hand.

The other problem with the ADS is the center detente;  while the controls may be continuously variable on either side of center, there is a rather large "step" in frequency created by the detente position on both sides of center.
