As I've mentioned on the forum, I bought a pair of Dutch & Dutch 8Cs from Purite Audio in December. Today I finally got stands, sand, and everything else needed to get set up. I need to do a little more listening before I post a full review, but my initial impression (from evening 1) is that these speakers sound impossibly good in our oddly shaped listening room.
- UPDATE AFTER WEEK 1 -
The 8Cs currently are connected via AES to a cheap Gustard U12 USB-to-AES converter, which is connected to a Windows 10 laptop running Foobar and the Tidal app. (I listen primarily to classical and thus cannot stand Roon, to which I have a 90-day trial that's going mostly unused.) To access the 8Cs' web app, which is needed to access to the speakers' internal volume control and boundary settings, they must be connected to Ethernet.
Purely from listening, my impression is that the 8Cs are superbly conceived loudspeakers.
I've run some slow test sweeps over the 8Cs, which have made obvious where room modes in our space are (there's a really nasty one just below 40 Hz). In contrast to other speakers I've owned, other large discontinuities were not present.
Despite the presence of unaddressed room modes and my use of cheap ancillaries, the 8Cs sound excellent. With apologies to Mr. Dallas Justice, I have listened a lot, and I can confirm that the cardioid midrange and DSP-driven bass boundary coupling are not gimmicks. Where room modes do not interfere, low frequencies are astoundingly realistic. For instance, on the Paavo Järvi recording of A Soldier's Tale, the bass drum strikes are uncanny. Reproduction of other percussion instruments and double bass on other recordings are similarly excellent.
The 8Cs generate an extremely specific sense of space (or, if you prefer, imaging). This sense of space is perhaps less ethereal than the sense of space that emanates from omnis or certain dipoles, but the 8Cs seem to deliver more spatial information than other speakers I've heard. A center image locks into place on every recording with something in the middle; there's no hint of dreaded "image instability." The 8Cs deliver a particularly remarkable sense of depth on a large sample of chamber music recordings, giving one a clear sense, for instance, that the string players are seated in front of the piano in piano trios.
The speakers are easy to configure. I was concerned about using a web-based app to control the speakers, but it has worked mostly without a hitch. As you can see in the photo, the speakers are both (a) toed in and (b) backed up to the wall: the inside and outside edges of the 8Cs are 9 cm and 13 cm from the front wall, respectively. Using the 8Cs' app, I dialed in 10 cm for the front wall distance. (The app provides only 10 cm increments.) The left speaker has a wall of windows approximately 72 cm to its side; I set the side wall distance for the left speaker to 70 cm. The right speaker has no nearby wall on the right, so its side wall distance is set to "free space." One might be concerned about sidewall reflections on the left in our room; however, I am not hearing any of the telltale signs of sidewall reflection problems, perhaps because the speakers are only two meters from the listening position. The tweeter waveguide and cardioid bass pattern may also mitigate reflections. Eliminating the tall rack between the speakers may be helpful, too. The rack is now approximately 60-70 cm from each speaker, and the rack is approximately 50 cm wide.
I've set maximum volume for the speakers in the Dutch & Dutch app at -25 dB; this is plenty of headroom for sane listening levels in our room on nearly all recordings. The app's volume control is not useful for fine adjustments, but setting max volume in the app will perhaps allay the concerns of those skittish about using software volume control for attenuation (as I was when I first got the speakers). With the app setting a hard limit on volume, fine adjustments can be made in playback software. I'm told that the volume controls in Roon, Foobar, JRiver, etc. are excellent; I hear no problem with them so far.
My only criticism of the 8Cs so far concerns their documentation. The manual is light on details, and, when I first set up the speakers, I did not know that, when using AES to connect the speakers, one must insert an included 110-ohm resistor (it just looks like a Neutrik connector yanked off of a mic cable) into the empty THRU output. The need for the resistor is mentioned neither in the 8Cs' manual on Dutch & Dutch's website nor in any materials in the box. (I actually thought that Dutch & Dutch had mistakenly thrown a Neutrik connector in the speakers' accessories box, but it was, in fact, the resistor.) Without the resistor, the speaker directly connected to the AES device will be silent, while the other speaker will make sound. I spent a couple of hours troubleshooting, but Keith of Purite Audio answered my question the next morning.

I'll report further as my observations progress.
Thanks again to Keith of Purite Audio, for a wonderful demonstration, and to the Dutch & Dutch team, for answering my many questions and creating these speakers. And many thanks to Noel Nolan of Skylan stands; the quality of the stands seems excellent.
