Got the D9 today, not bad at all for the price.
Connected using Spitfire MK1 DAC.
The upper mids & treble lack resolution & bite. The Sub being large has nice scale. The satellites have rather small drivers. Not enough weight & scale in the mids although the lower mids sound pretty neutral without being thin.
Overall better than the logitech z523 that i was eyeing initially(too harsh highs).
