I run my iPod Classic with lossless tracks through a Pure i20 into a Naim NAC62/NAP90 combination and Dynaudio Excite X12 speakers. The iPod does not have the same level of performance as my Arcam CD73T, and that really is in all departments. So, I plan to use the Pure i20 just as a dock and run the digital output into an external DAC. I will audition the ARCAM irDAC and Audiolab's M-DAC, but are there any others to consider? Is the Rega DAC worth a listen? I have read a few reviews, and I suspect that the M-DAC might be a bit clinical for my tastes but an audition will soon clear up that preconception. Any ideas?
