I hooked up the M1 Series II yesterday and did some A/B'ing with my Gustard R26. Does the M1 sound over 6 times the cost of the R26, no, but it does sound better. I am not well versed in technical terms of audio but the musical instruments sound more real. I really do have to give the R26 very high praise for its great sound qualities at the given price point.
To put the R26 further on the pedestal, I found that stepping up to the Aurender N200 did not sound 3 times (the cost) better than the R26 using it as a renderer via its LAN connection.
I'm done for now, thanks to you all for your help & support on my audio journey, time to sit back and enjoy the music!
