Jolida JD 100a - help w/Buzz when using headphones


I recently purchased the Jolida JD 100a and discovered that the CD transport mechanism, particularly when it spins the CD, is audible as a "buzz" in my headphones (Sennheiser 580s). It is also audible from the player itself. Is this normal? Or is this a defective player and/or correctable with lubricating the mechanism? Help.

Thanks Mtbrider. That's the material I was referring to in my prior post. Did you do any other mods that made a difference? I think Verastarr has a mod package and, if the damping can possible help the buzz, perhaps that is a better alternative to servicing at Jolida.
Thanks for the input. I guess the sound of the CD spinning comes across as a "buzz" in the headphones (perhaps buzz is not the best word to describe it). I also hear the CD spinning inside the player but, the noise is continuous whilst the disk is spinning and only stops when I hit the "stop button and the disk stops spinning. It isn't really that loud but I can hear it from across the room, that gentle whirring noise inside the player. I never had this with my old Yamaha player and didn't expect it with a reference player like the Jolida. I did get it used and have contacted the seller. I expect I will get better info on the problem from Audiogon.
Ladavid-your impressions are in line with my experience. The Jolida can't really drive the Senns and the sound is confined quite a bit. What mods does your Jolida have? I saw one mod that involved chassis damping with material containing an outer layer of copper. Perhaps that stops the transfer of disk related noise and interference from reaching the tube headphone output.
I sent Mike an e-mail but have not had a response yet. I have sent him e-mails in the past with good responses and information. I will likely call him when I get a chance in the near future. I certainly appreciate all the sincere concern for my issue!
Dear Rysa - I have just purchased the CD player and the tubes had been rolled by the previous owner. Thanks for the tip. I will put checking the tubes on my list of possible solutions.
