I just put some of my old reaching for the lasers tracks on - I can't really compare directly to the Aqua as its all unplugged at the moment, and I dont really listen to dance music anymore, however the Bartok is creating this huge soundstage and really expresses all those curves , lulls and highs, of the music, the build up crescendo's are immensely impressive. To be honest, I have no idea what he is talking about, it sounds breathtakingly good.
I hazard guess the 'smoothing' he is going on about is what digital sounds like when all the 'noise' is removed - I've found this going up the chain to my current kit and adding in good switches and LPS's - so maybe the DCS is actually too good in that respect. He wants/expects that 'noise' or 'hash' or whatever that it is that he hears in cheaper DACs do, or he is biased based on measurements, or maybe it is all system dependant.
It always good to get multiple pov's but the proof is always in the audible pudding. Listen for yourself if you're in the market for one, we can't judge on graphs, only what he hear and feel.
Using tracks
K90 - Breathe
Lab 4- See No Evil
VNV Nation - Dark Angel
Putting my usual singer/songwriter folky stuff on...and absolute heaven.
I should mention I am using it as a streamer and a DAC through Roon.
