Things were not rosy after purchasing mine April, 2012.
I had used the unit for about 3 weeks before the right channel faded out. After much Skypeing with "Katherine" from Salience-HIFI-Audio in Shenzhen, they sent me a main board for the phono box, which I installed. After repairing, I have not had a problem. I leave it on 24/7.
I used several caps from the old board to beef up the new one. I replaced all the small wires with fine teflon-covered solid copper and the input wiring I replaced with cloth insulated solid silver. The output caps I trialed with Russian K40Y paper-in-oil and felt it was too suave and lacking detail but addictive. Between those and the OEM Solens, I most like the Robert Hovland SuperCaps. Neutral, revealing, 3D, transparent and very engaging. The goal was to further open up the top octave to balance the enhanced bass from Nichicon KA audio caps I added to the power supply. What a nice change in dynamics and bass presence the Nichicons provide.
As a side note, Jasmine already installed PP snubber caps on the power supply rectifier diodes. I also replaced the umbilical with Jasmine's upgrade cord. Other upgrades are planned.
Biggest drivers of change? 1.) phono box coupling caps followed by 2.) KA caps in the power supply. The wiring upgrade is definitely discernible but not as quickly noted.
