Hum, if it is a bit shorter and succinct that's just the way I wrote it. It had nothing to do with the length of time I spent getting my take on it.
As far as the overall performance of the Wavelight and the M3 both are superlative at making music. The Wavelight for my taste is very slightly warmer sounding with a touch more "meat on the bones" imaging. However, some listener's would say the M3 is slightly more accurate at how it presents the music. Which do you like better, great solid state or tubes? Neither is right or wrong it depends on personal taste and system synergy. Both have killer analog volume controls that allow you to drive your amp directly and save a bundle not needing a preamplifier.
Rockna Audio does not believe in having a streaming device in the same chassis as its DACs. The M3's new streaming board is world class, yes it costs you an upgrade if you order the M3 with the built-in streamer, but still is less costly then Rockna Audio's Wavelight plus their separate streamer. If you only stream the M3 might be a better choice for you.
