I´ve tried the R1 briefly. But to me it seemed very noisy. Soo much in fact that I wonder whether there is any use at all going for 24 bits. I tried with line in, mic in and built-in mics with same results. 24 bit to me is of no use unless the box has really good analog circuits, much of it is about getting a higher ratio between signal and noise. (Theory says that each bit represents about 6 dB of S/N ratio).
What are your experiences, or was it only the one I used.?
