Jolida FX Tube DAC


Anyone tube rolled this unit with good results?

I am thinking of upgrading my DAC, but I want to hear some other opinions of tube choices before I sell this unit.

Thanks in advance

This is an aside but if you have the FX DAC or the integrated and don't care for the bright blue LEDs there are a couple of things you can do about it. I have the FX10 integrated on a shelf directly above the computer monitor in my office and the blue LEDs were very distracting.

I first took out the tubes and put a couple of layers of dark red fingernail polish on the LEDs, which created a much less obnoxious purple-blue color and cut down the brightness.

After awhile I felt that wasn't enough so I took off the bottom plate of the amp and clipped one of the leads to each LED. It was a very simple process and I was much happier with something that now looks like a tube amp instead of a video game.

Really nice amp, I use it with a pair of JohnBlue JB3 speakers and it's a wonderful combo.
Jedinite24 - The 5751 was recommended to me but because I'd received several pair of vintage 12ax7's in a tube swap I never pursued any of the other types. I've used vintage and new Tung Sol, RCA black plate, Matsushita, Sylvania/Baldwin, the stock Electro-Harmonix and reissue Gold Lion pairs. The stock tubes are nothing special but all the others sound great and the differences among them are not that significant.
