I have not heard the Bricasti M1 in any sort of details but I did listen to the Rowland Aeris in 2 diff locations during the RFMAF2013 - one was at my friend's manuf shop before the show & the other was in Rowland's room during the show(with Jeff Rowland himself doing the demos). That Aeris DAC is really very good sounding. It would be on the top of my list to audition/buy....
