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!

I'm not sure about the Jolidas, but other Chinese built manufactures also use an "A" and "C" designation along with some that have no letter designation. My deductive reasoning has brought me to the conclusion that "A" means for the American Market and "C" means for the Chinese market.

For an example, take a look at some of the Shanlings. The cheap "grey market" units often have a "C" designation after the model number.

I don't have any proof concerning my findings, just a reasonable suspicion. Personally, based on my hunch, I would not want a "C" model as it might not have warranty here and might have some different components.

Just my (possibly wrong) $.02 worth!!!!

Enjoy,

Hey thanks for all the info guys! :)

I love the player, haven't had a chance to do any tube rolling. I was planning on doing some comparisons between the Sovtek LPS tubes and the stock tubes, but since for whatever reason my player didn't have the typical stock tubes I am just sorta stuck with only knowing one sound :)

I'll look into some 5751's, they tend to be pretty pricey if I recall. Between this player, my ONIX Ref 3's, ONIX A-120 MkII, and CinePro line conditioner I'm a bit low on funds, and the Sovtek's seemed to have the concensus as being the best tube sound for the money with this player, or at least in the threads I came across.

I'm really loving this thing though. It's very revealing, but I never find myself whincing in pain while listening to even my most horribly mastered albums, and the bass is very clean and tight, which I didn't expect coming from a tube component.

Cheers!

You should get a pair of the Electro Harmonix 12AX7s. My Jolida had Sovteks in it too, but the EH tubes brought it around in a big way. And dampening the chasis is a good idea too.

What would you say was the biggest difference between the Sovtek's and the EH's?

The Sovtek's seem to have pretty decent treble extension, they create great well articulated bass, and the mid range is pretty fluid.

I'm just curious what the sonic difference you noted was so I can see if it's a type of change I'd be interested in for my system before I buy another set of tubes :)

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!
