D18:
Everything pops, with wicked detail and instrument seperation. A very 3D soundstage.
IMO, the D18 is a better sounding dac. That's saying allot when the QB-9 is worth 4 times as much.
Now if I was a vinyl lover wanting that warm analog sound from my digital play back, the QB-9 might be the better choice.
I'm driving the D18 with a M2Tech Hiface by the way.
Went and plugged in a QB-9 again and I think I need to retract my statement that the D18 is better. The Bass might not be as focused on the QB-9 but there is a certain richness across the spectrum. The music just flows. The instrument timbres seem to be more accurate on the QB-9. Vocals are quite magical on the Ayre.
Part of the difference might be that I pulled the D18 all together and used the same conditioner, USB power supply, cables and balanced outputs this time.
Maybe the $2750 new price turned me off originally. I've found a used 24/192 version for $1800, my common sense isn't playing with my hearing at that price. :)
