Did some quick sweeps on my speaker stands of two speakers. I would say immediately off the bat while switching between the Reference 1 and the Genelec 8341, I feel like the 8341s are "clearer" especially in the mids in the sense I'm listening to more of the direct sound, whereas with the KEFs I can hear more of the reflected sound. To me the KEFs sound a lot more laid back and it's better for casual background listening with mids that sound more recessed, while the Genelec sound more in your face in the mids, due to my perception of hearing more of the direct sound--I guess in Harman tradition, I would describe the KEFs as sounding more "spacious". Also the mids are more nasally/honky on the Genelecs like I mentioned earlier, similar to the Revel M126BE being more nasally/honky than the Revel M105s. I think it's probably the difference in sound power in the 400-1K range. Obviously in my room you can see some bass nulls at 50, 70, and 90hz.
Both before and after Dirac correction (default curves), I slightly prefer the Reference 1s for the more laid back sound. The Genelecs sounded really wooly in the bass before correction, bass presentation reminds me of Sennheiser HD820 (Genelec) vs HD800 (KEF), as in the rising amplitude in the bass causes the bass to lose some definition, definitely needed to lower it somewhat with EQ. Might be because I'm pretty close to the backwall (about 9 inches away). While the Genelec's by default have much higher bass amplitude by their measurements, by ear the Kef's sound like they have a lot more dynamic slam to them in bassier tracks. This shouldn't be surprising--the KEF Reference 1s are twice the size of the 8341s. The 8341s have really impressive bass extension for their size, but I guess when you equalize for extension you do give up some dynamics.
Other small nitpicks, the Genelecs have a pretty noisy noise floor using XLR inputs. When switching to AES the amplitude of the hiss is much lower, but it's still not in the same ballpark as using passive speakers + amp. (With AES the hiss sounds the same as with nothing connected. So this appears to be a baseline noise generated by the amp). At a ultra nearfield listening distance (say 1.5') it's still audible with nothing playing, but your mileage may vary due to your room's ambient noise conditions.
