Chris Johnson (former President of Sonic Frontiers) offers two different upgrades for the Jolida JD-100 (a level 1 & a level 2). The level one will provide about 85% of the sonic improvements offered by the level 2. I saw the upgrades from Sound Odyssey, yet I do not agree that the clock needs to be replaced (or that it will offer lower jitter when it won't). Compare the modifications steps of the Sound Odyssey modification with those from Chris Johnson (Parts Connection) and then idendify which provides a better value for you.
I have the level one modified JD-100 now and it's not about to leave my system anytime soon. that should be all you need to know. I'm not saying the level 2 mod is not worth the investment, just not worth it to me consideing how wonderful the level one sounds. Unless you have over 20k in your system, I don't think you will hear much of a differece between the level 1 & level 2 mod (but again, that's just my opinion). In the end, you must decide for yourself which unit to purchase.
All I can tell you is that you should contact Walter Liederman (Underwoodwally) on AudiogoN and talk with him about these modification. Walter is a Jolida dealer and will not be undersold, especially on a modified unit. I've known Waler for many years now, and he has proven to me on MORE than one occassion that he would rather sell what is the best for me rather than something more expensive that will make him more money....again, integrity and knowledge to me are the two MOST important characteristics I look for when purshasing high end audio equipment these days. Wlater has been in the business for well over 20 years and I know for a fact that this man KNOWS the audio industry and the competetion. He worked hand in hand with Chris Johnson developing the above identified modifications.
In conclusion, I love my JD-100 w/the level one mod. I replaced the 12AX7 tubes that were apart of the level one upgrade with gold plated Telefunken 12AX7s and the match is incredible (mids to die for). I listen mostly to female vocals and jazz where the mids are everything....
Good luck with your choices...
