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

I listen to my Grado 60's directly through modded Jolida 100. Get serious pops when I plug phones into Jolida already on but no buzzing ever whether through phones or speakers. Sound from this combo is pretty interesting - the ultimate laid back - at times slow sounding - warm tube sound that is totally different from how the player sounds through Musical Fidelity 3.2 amp and Paradigm speakers. I stayed away from Senn's because I heard feedback on head-fi that they might be hard for the Jolida to drive by itself. No ideas re buzzing though.

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 have the Underwood Level I mod - coating is Sound Coat - don't think copper is involved. You check mods out at Underwood site. Wish I could help you out with your buzz. Mike Allen at Jolida was pretty repsonsive when I had a problem with my Jolida.

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!

The chassis damping material with the copper shielding is available from VeraStarr. I have the treatment inside my JD100 and think it makes for a nice, if subtle, improvement in the sound. I don't know how it would work for your buzz problem.
