Hi there,

You can also say there is no difference between Siemens and Tesla because it's always E88CC just from another factory. After some more experiments with upgrading my headphone amp and its PSU I find again the AD797BRZ to be the best, in terms of overall transparency. I sold the Earth so I cannot say how it helps but my Sun v2 improved when I removed the capacitor upgrade. The ones I use in my DAC are better and those from Evox just were making the sound worse. So, I strongly recommend to anybody removing the cap upgrade or placing there some decent electrolytics, i.e. Black Gate STD. |
