Ok rob I'm back from my testing Vega v DA-06.
So without doing a long winded review, here's what I thought of the Vega:
more forward sounding
slightly plastic sound to all instrument except acoustic guitar (really good)
lovely bubbly bass
high and wide sound stage
liked messing about with all the filters and clock speeds etc
built in digital preamp if you need it
and now the Luxman:
instruments and voices sound more natural and convincing
Lovely rounded sound to all instruments
deep bass if it's in the recording
high and wide sound stage (Vega edges it though)
more distant presentation
interestingly the presentation from the Vega was just too intense until I moved the speakers further apart when it smoothed out considerably
also detail levels actually seemed pretty comparable but it possibly seemed like there was more detail from the Vega just because it had a more up front presentation. Neither dac will disappoint in this area.
My my preference is very much for the Luxman but I was surprised how engaging the Auralic was particularly with acoustic guitar. I just think that the naturalness of the luxman makes for better long term listening.
hope that helps
