has anyone had any problems w/ Jasmine phono LP2.0

While I haven't used them personally you can try calling American audiophile in lynbrook,ny 516.887.7530, they have a veteran repairman 40+ years in the business.

Check first your amp., then phono-cable , then the tonearm
wire and the cart. With a simple Voltmeter you can check
all the wire. My problem was the left channel tonearm
wire which was sometime on and sometime off ( loose contact).

I personally own 2 of them and have not had a problem with either. I have recommended them and have only heard of one with a problem. The person with a problem said they sent it back and got a new one from Jasmine in China. I had one of their headphone amps that was damaged in shipping. They replaced that one with a new one. From what I can tell, they have been responsive and the units have performed well, in fact, better than units I had that cost 3 or more times the cost. The only problem with sending it back, of course, is the shipping charge. It seems like it is less expensive for items to be shipped here than for US to ship to China. I wonder if the Chinese government is subsidizing shipping from China to make their products more competitive.

Thanks to all for your time and response.
All the connection s appear to be in order
With no shorts. It tried switching inputs
To my main preamp ie tuner/phono swap
The problem didn't go away.
Looks like its going back to China.
I will however contact American audiophile
To speak with their tech.

Maybe I don't understand your description, but if you switched between a tuner and your phono stage and the problem persisted, that would mean that the problem is not necessarily the stage. Can your system play digital? If so, I take it the issues don't arise when using it?

The same sort of thing has happened to me. Once I could have sworn a tube had gone bad but it turned out one of my ic's was problematic. It took me days to figure it out.

But if it is the unit, I can't believe they're making you pay to ship it back! 3 times!
