New Version Jolida JD502P issues.

Great thread Wolf! Enjoy the humor. I need to learn to inject more into my posts. As you know from another thread, I own the Jolida Fusion pre and consider it excellent. I have found the Jolida MD people to be very helpful. Have only compared it to a Audible Illusions 3A which I sold. RE my tube post, I received the Mullard tubes but have not inserted them yet, is that necessary to achieve the benefits I was hoping for?

I'm in a similar boat with the Wolf man. I've put in a matched quad of Tung Sol KT-150s in my factory modded Jolida JD-502P as well. It does run hot but sounds SO good.

My main benefit from NOS 12AT7 Mullards in the "phase inverting" roll in my amp is the entertainment value of the start-up flash. And they supposedly last a long time while sounding great or at least not making anything sound not great. Recent 150s and new Russian Gold Lion "matched everything" 12AX7s have kicked the 502p up a notch or two, whether it needed it or not. Also I don't notice the amp being that much hotter with the 150s, although the heat is focused higher up due to the size of the damn things, but it seems normal and no fires have broken out...I just have to be even more careful not to burn my knuckles when tweaking the bias.

I purchased a JD502B several years ago. I got them for a great discount, just as they were being discontinued in favor of the JD502RC's, which added a remote control. I had been enjoying a vintage Marantz 2325 receiver prior to that, and prior to _that_ a Philips receiver I bought off Cambridge SoundWorks for a couple of hundred bucks in the nineties.

Just as the Marantz made the Philips unlistenable, the Jolida in one fell swoop dragged me into the rarified air of so-called "high end audio."

Now, I don't doubt that a more expensive amp would sound even better, but, for the life of me, I am content. That amp is quite simply amazing, and a terrific bargain.

want to let you know Jolida will changing their name to JFI (J hifi) and get away from the confusion of the ongoing lawsuits that cannot be resolved across the seas. Borders. At one time the 502A model got some bad reviews dues to QA issues. A lot of improvements made since then. The 502CRC or 502P either one are really nice sounding amps. Real nice. And we sell a lot of both. What would sound real nice? a 502 and a pair of Pioneer HPM 100 speakers, or some of the older, nicer JBLs. Those vintage speakers with paper cone drivers sound nice. Those have such a relaxed sound.
