I want to report an observation I made with cables and adapters. I have a ponoplayer balanced cable from Venus Audio that I use with the Sennheiser 6xx. When I got the Jot, I bought an adapter from Dyson Audio to convert the dual TRS jacks of the ponoplayer cable to 4 pin XLR to use with the balanced out of Jot. The result was worse than I expected. The treble was subdued and the bass became muddy. Compared to the SE out, the difference was clear. Not sure what the problem was, I decided to buy another balanced cable with Litzy copper wire and XLR connector for $65 from Amazon. The result now is night and day. All the issues with the previous cable/adapter solved and I can really hear the sound everybody talks about in this thread. It seems like, somewhere in the jacks and adapters, the signal was spoiled. Since I am not electrical engineer, no clue what the problem was.
On a different note, I find the DAC inside the ponoplayer pairs very well with Jot. I am using the balanced out of the Ponoplayer to feed into the Jot, then listening thru balanced headphone out. Comparing the same flac files thru Mac/Audirvana-->Jot internal DAC, the sound was more congested with less instrument separation, although the difference is subtle. So I am sticking to the ponoplayer as DAC for now. Has anyone compared the ponoplayer DAC to that of the mimby for instance?
