I am interested in Rega Dac and Arcam rDac, I would like to know if Arcam can compete with Rega.As soon as possible, I am hearing the Arcam,but I wonder if anyone else did this comparative. I know Arcam is cheaper, but I am interested mainly in usb input,and Arcam usb is asynchronous, which for me is great !However , the Rega looks fancier !
