Reviews on JungSon amp/preamp combo: JA-1/JA-99C


Any of you know the JungSon brand? Is it considered to be one of the better brands from China?
I came across these two reviews on Chinese made JungSon amp/preamp.

Both reviews are very favorable. However, I wonder how much would I trust the reviews and reviewers. Has anybody tried this amp/preamp combo? 
Any input would be appreciated.

I’ve had a few things from Jungson, all purchased years ago so maybe they have changed. But my experience with all of it was bad enough there’s no way I would ever buy anything from them again. That goes even if they were made in the USA. Once you have company reps come out to your house, see first hand their amp is defective, promise to replace it under warranty, and then totally unprofessionally stop returning all your calls, well if you are still willing to give them your money at least after hearing my story you won’t be able to say nobody told you to expect to get ripped off.

My dealer by the way wound up replacing the amp at his own expense. They refused to honor their warranty even to him.

Caveat emptor.
Thanks for your reply. That's pretty bad. You purchased more than one JungSon gears and they were all bad?

I did not know this brand, but just recently came across a youtube review from ZeroFidelity. I don't know the guy (Sean?) at ZeroFidelity, but he seems to know what he is talking about and he doesn't seem to be a guy who is going to review a junk product and give a favorable review. But we all know that most products coming from China have reliability and support issues even though they may be good in the beginning.
The second reviewer pretty said the same thing the first reviewer said.

More comments, both negative and positive, would be appreciated. 
Also bought a power conditioner. Sound was okay, construction extremely cheap, really nothing more than a potted transformer and cap. So I tossed the outlets and crap chassis and still use the guts of it today. Then there were a couple of interconnects, still have and use those, but the finish on the RCAs went to crap within a year or so. Just overall poor quality stuff. 

This was all like 20 years ago. Its possible they're better. Couldn't imagine being any worse. Its the customer service I would worry about more than anything. Besides of course supporting the CCP. Which don't kid yourself, you buy it you are. But you meet a couple guys like I did, guys pretty high up the distribution food chain, have them come in your home, lie to your face, lie to your dealer, lie in a way so blatant that looking back on it now I would have told them to THEIR FACE what you're saying makes no sense you can only be lying. But 20 years younger and dumber I decided to hope for the best. 

Which is what you get if you are young and dumb enough to buy Jungson: hope. Good luck with that!
