EMM Lab CDSD transport motor resonating


Has anyone experienced any sort of resonating sound coming from their CDSD when playing certain CDs. This has happenned to me on two discs, the latest one with "Shirley Eikhard - Stay Open, Track 1 - Take It To The Max". I assume it has something to do with the rotation speed of the transport on that given track, because it slowly fades away past the 2 minute mark, and doesn't occur on any other track. It is extremely annoying and surprising for a $7K transport. I'm starting to wonder if I need to send it back, but I'm hesitating considering how difficult it has been to get it in the first place.

Finally got my transport back last night and plugged direct into the wall made no difference in terms of mechanical vibration noises.
Oneobgyn - may I ask how came you have owned THREE CDSD transports ??? Were they all defective ?
Nikki- Something is very strange. I owned one of the original CDSD (metal tray)and it had a very annoying ticking sound. I replaced it when the CDSD came out and it has been bulletproof. I know several people with the new CDSD (plastic tray) and no one has had any problems.

BTW, I have plugged it into power conditioners and directly to the wall and it performs flawlessly either way.

I wish I could say the same, my 1 year old CDSD with a plastic tray is now making loud resonating noises with certain CDs, which can sometimes be heard over the music from my listening chair. I am waiting to hear back from my emmlabs dealer regarding a solution.
Rcupka,
The distributor told me that my two previous units were quieter than the average. So either my expectations are out of line, or there are many others.
Just want to make it clear that my latest service call was not due to mechnical transport noises. It simply stopped working. This latest CDSD revision is my quietest so far.
