What is after R2R2000? Let's face it, sooner or later this dap will die, and there is so much PCM1704 left in the wild. What is life after R2R2K? I only know of another DAP which uses R2R technology for conversion, which is well over 5000 USD and very hard to try, let alone purchase. Sadly the back glass plate on my dap developed a crack, which is the first time I ever had a product develop a fault on me. Despite the humming noise that my dap produces when I have the screen on, the sound is so good that I'm willing to live with it for a little while longer. Sooner or later I need to send this dap back to get it checked. In short, there is so much wrong with this dap, but one thing they sure got right, and that is the sound which matters the most.
