Jolida JD-9 Mod II

I have the stock jd9 and upgraded all 6 op amps and have tried several different tubes. I like CBS 5751's with my system.

All of this is possible with about a $150 investment and the time to replace the op amps and tube roll.

Tremendous improvement in sound.

I trying to decide on upgraded capacitors which will be a fairly simple solder job. Maybe another $100.

You can also add your own sound deadening feet and material on the inside of the metal cover and base. I run mine with the metal cover off.

My point is that you can get most of the parts connexion level 2 upgrade for around $300.

The pieces you are missing are not the parts that make that much of a sound difference.

Do it yourself and save some bucks.

Interesting how every tube and system is different. I have some RCA 3 mica black plates and do not like them in my steup as they seem to not have a good depth of field and are more two dimensional.

What capacitors are you all using?

To answer Wrayman's question, the op amps, in my system, gave a lot more detail and everything sounds closer to live. I also think that the mods I have made make the JD9 sound more alive because it is well...more fleshy and organic.

I am still wanting to play with the JD9 adjustments on the back. The gain is higher than what I hear with my CD player and I suspect that if I get the gain down a little bit more, the sound will improve further.

I have a Ric Schultz modified Oppo 105 that is really quite good. In fact, I think it is as good as $5K Esoteric I had for an in home audition. Ric Schultz's mods took the Oppo 105 to another whole level due to more detail and more weight while remaining musical.

However, I prefer the album sound which I think is the tubes.

Again, in my system.
