DAC1421 in the house. Not mine though (the loaner program). A little bigger than my adi-2, but still very cute. I love this level of small sizes -- office/desktop-friendly. Right after turning it on, the sound is a little lean and harsh-ish on trebles. Not as severe as day 1 of Gungnir Multibit though. I know I know multi-bit needs time to be stabilized... Will have a shootout party with adi-2 dac prol on Sunday or so. Hope 1421 gets warm enough until then. P.S. I assume this thread is also for 1421, because presumably 1421 and 1521 share lots of sonic characteristics, as described in Soekris webpage.
