ARtar, it sounds like you are really having fun with all this, and I hope you continue to enjoy this process. With the various selections you are choosing from, you are bound to get very good sound.
Just enjoy yourself and get the things that make you happy.
We are just trying to provide some insight that will help you to make your decisions about some of the details.
Regarding your questions about motor controllers, there are some things about DC motors that need to be known. First, they can be the smoothest way to rotate the platter. But, they have no "speed lock" like AC synchronous motors do, and the speed can slow down over the course of playing a record, unless something is done to keep it at speed. This is due to "stylus drag" and it can add up to a significant loss of speed over the 20-30 minutes of an LP side. There have been a variety of methods employed to keep the DC motors at correct speed, and they all have their plusses and minuses. The bottom line is that the heavier the platter is, with more rotational momentum, the less likely that stylus drag will significantly affect the speed. With the heavier platters, even a TT which uses speed controls will not have to engage in compensating pulses to the motor very often, if the platter stays at correct speed in the first place. I have a Teres(as you know) and it even has the lightest platter in the Teres lineup. The motor housing has some LED's on it to show when the speed has changed significantly enough to apply a correction. In fact, the red(correction)LED light never comes on during play. It only comes on when the platter is first starting up, and seeking 33.3rpm. Then the green light comes on and stays there throughout the LP side. So I really don't even see any corrections taking place, because the heavy platter keep it rotationally stable. However, I do know that if something severe happened to the platter speed, that the controller would account for the change immediately. Also, the Teres uses a strobe on the platter to continuously monitor the speed. This is quite different than monitoring motor speed, because if there is belt-slippage, the motor will "see" correct speed, but the platter could be off-speed. We always want to know the platter speed is correct.
