Differences in Jolida JD-100's?


Hey,

I just bought a Jolida JD-100 from Underwood Hi-Fi. I love the player, but I just got curious about all the distinction suffix characters on the model name, ie. JD-100, JD-100A, JD-100C, etc.

Does anyone know what all the model numbers are and what the differences are between them, and then further how one would go about telling what model they have?

Oh one strange thing about my player was that when I went to replace the stock Chinese 12AX7's with a pair of Sovtek 12AX7LPS's to my surprise a pair of Sovtek tubes were already installed! Go figure...

Cheers!

ozzy,
what did you use to dampen the chassis? dynamat or something similar?

what did it change about the player?
i'de like to try it, but i first would like to know exactly what to expect.

thanks!
Changing the tubes in the JD-100 changes the tilt and the tonality just a bit but, it does not change the basic character of it's sound. Which, is very good in that it is fluid, full(slightly bloated) and musical. However, the soundstaging lacks the definition and placement of top line dacs such as the relatively new Musical Fidelity Trivista 21 driven by a cheap Pioneer DVD player as a transport. This I have compared at length so I am confident in my remarks.
Ketchup,

The Sovteks are weak in the midrange, which is a trait of this tube in any application. The EH tubes retained the top and bottom extension while filling out the midrange nicely. I am a stickler for the human voice, if it ain't right, I don't want it.

I am using a Sonoran Desert Plateau PC plugged into a Blue Circle MR 1200.
