This is what many of us have wondered about, does the change from the old AC motor to a DC motor eliminate the hum/buzz completely. I would be interested to know if you have conducted the acid test, turn the volume on your pre-amp up a bit and place the stylus on the lead in grooves (with the platter turning) and see if you hear any hum/buzz from your speakers. Additionally the hum/buzz can be easily heard when the stylus tracks out at the end of the record, and you clearly hear it between tracks. With the old AC tables, you could place the stylus on the lead in groove with the motor OFF and it was completely quiet, it's only when that motor is on, and the platter is turning, can you hear the hum/buzz. With this AC hum/buzz problems literally all over the Internet, it's beyond belief that Pro-ject never publicly addressed the problem anywhere, and continued to sell thousands of the HUMMING AC turntables. The DC version was introduced to address this problem, but you will NEVER see Pro-ject acknowledge the DC version was introduced to address this terrible problem that they would not acknowledge. dougotte, I hope you conduct the test just like the man with the green Carbon on YouTube and confirm you have no hum, many people will want to know what you find out, I know I would. It should be noted, Pro-ject decided to charge an additional $50.00 for the DC table, at least on Amazon.
