Motor Controller ugrade for Raven One Turntable

I see by reading some relies above it's apparent you guys have a axe to grind in relation to TW product instead of just staying on topic, why is this.

Jealous! Envious!

Some of the statements made are just nonsence and non constructive in relation to this specific thread and what the OP has posted.

It's find to flavour another product but to start babbling on with silly comments in the end only demonstrats the lack of your credibility.

I'm a proud owner of a TW Black Knight, I have owned a few other TW tables prior to this one but I'm still curious in discussing the thread at hand, being open minded.

I have friends who try different belts, thread, mylar, turn off the sucktion of the platter, use different motors and on. Some of these changes are very noticable and positive, others are questionable.

I am not questioning the quality of a TW turntable and they are probably a fine product. What I am questioning is the reason for an "astounding" difference in sound by just changing a motor controller, whose sole purpose is to make sure the motor turns at a certain speed. I am questioning how much off speed the stock motor must be if the change is "astounding" and if that is true, can I get the same "astounding" change with my turntables by changing the motor controller.
As far as I understand, nothing else was changed to get this "astounding" result.

Hi Manitunc, you know how this hobby is sometimes things are heard by some and not others. I believe our minds play with us at times. I've been present with some demonstrating gadgets and they are most defiantely wowed but personally I'm not getting it.

Some post using the wrong words "astounding" could be one because they were just overly enthusiatic at the moment, I know I have personally done this.

I'm just trying to understand what is going on if this in fact is taking place, just as I have mentioned in my prior posting. In friends set-ups I have heard the differences by just changing different belt materials, belts to mylar tape, string etc.

All of these are driven by a motor which is usually powered by a controller of some sort if external, what ever the material is attached to the motors spindle and then around the tables platter.

So what's going on?

Much of that assumes a constant motor speed, which is a big assumption. But if you have a constant motor speed, what is it that different motor controllers or belt material or anything else is doing to affect the sound. By definition, a change is either adding something or removing something. So, what is the motor controller doing, other than maintaining constant speed, that is adding or subtracting from the sound that comes out. Same with the different belt materials.
Of course, you can go around and around in your head looking for explanations. but assuming the changes are real, they should be able to be defined and then reproduced. Maybe we cant do that yet with test equipment, but that doesnt prevent us from trying to understand what is happening, and thats what I'm trying to do, for my own understanding. And maybe, if I figure out some of the parts, my little brain can figure out the big picture.
Maybe the motor controller takes out little micro vibrations and thats why it sounds better. Maybe a different belt material does the same thing. I have to guess that it has something to do with vibration, because thats what the stylus picks up. Of course, there are issues of time domain and such, but that is just a shifting of when the vibration occurs in relation to others.
Again, assuming the squiggles in the vinyl groove are passing by the stylus at a constant, accurate rate of speed, the sound should remain the same regardless of other factors unless somehow other vibrations are being added or subtracted from what the stylus reads. then of course, we have what happens after the stylus sends out its signal.

I continue to be amazed at how many responses you can get that have nothing to do with the question that you asked. I just asked if anyone had tried replacing the standard motor controller with the AC controller. I only got 2 reponses that even came close to answering my question.
