There are so many variables involved with turntables and their setup. No 2 listening rooms are the same and no two people have the same system. I have read in this thread where someone has a few days of quiet operation and than the hum comes back. I would like to relate one other source of noise I have encountered and it's no fault of the turntable. I was also having intermittent noise problems, and I will be clear, it was electrical, not mechanical hum or rumble from the motor. Some days things were fine, the next day buzz, turns out the LED pot lights in my kitchen upstairs and on a different electrical circuit is causing RFI that the cartridge is able to pick up. This is unfortunate but not the fault of the table. I am going to try different dimmers to see if that helps. Until then, if I am doing some critical listening I need to turn off the lights in my kitchen. Sometimes it is easy to get on the bandwagon, myself included, and start putting down a product before all the variables have been checked out. As of now my Essential II is working very well and I am happy with it. I have replace the power supply and the slipmat with a slightly heavier and stiffer felt mat. Both of these were at almost no expense, $5.00 for the wall wart and the slip mat was free at last years record store day. I still plan on getting a Debut esprit, once I scrape up a few more dollars. One last thought, when I was in my teens, the music was more important than what I played it on, I hope I can get back to that reality, after all, that is why we have turntables. Isn't it?
