I know that this post is a few months old, but wanted to give my listening perspective with the DQ10s. First, they like clean power with a lot of headroom. In my initial impression about a month ago, I used a Primaluna integrated tube amp with EL34 tubes and they sounded great in my small room (10X9X9) playing at 11:00 o'clock on volume and hitting 85db peak. I then used an Onkyo Integra integrated amp and the DQ10s sounded thin and the mids/bass almost non-existent (bigger room and not enough RMS watts). While the specs on the 5.9 integra should have been good enough it just didn't do the DQ10s justice. So I put the PS Audio 200c on duty (8 ohms @ 200, 4 ohms @ 400 & 1.5 ohms @ 1000) with a Sanyo Plus Series amp (vintage warm sound with no hint of sibilance). The change was incredible, to say the least. The mids/bass had a fullness that felt like I added a sub and imaging, clarity and air (like somebody turned up the reverb button where none exists) was awesome. Room size increased to 15WX20LX10H and playing at 11:00 or 12:00 on the volume barely gets the PS Audio warm to the touch (3 hours playtime today 10/26/2018). I compared the DQ10s to the Martin Logans with built-in subs (ML had more air but mids/bass were comparable); Wharfdales (laid back and warm which is similar in the DQ10s); Klipsch RF 7 (more clarity in the highs but can be fatiguing if not paired with the right equipment) and others. Based on my listening experience in my rooms (3 music rooms with 1 dedicated) the DQ10s can more than hold up their own in the right room with clean power and a good source. I have the DQ10s 32" from the back wall and 20" from the side walls and I'm six feet in the sweet spot. One final note. I got my DQ 10s in very good shape for $100 a piece (mirrored and cones were redone by the owner who had 5 DQ10s and some Advent speakers) and was a tremendous find. The PS Audio 200c can be had on eBay for around $700 the last time I looked.
