I have ordered the Noires. I am looking forward to them later this week. I have the DCA Aeon X Closed from Drop. They need a lot of power, so will the Noires. I am pretty happy but have gone through the challenge of finding a good frequency response curve for EQ. I started with the "Robbo" curve and boosted the bass a bit. This seems to sound MUCH better than using the Closed RT EQ that some have recommended.
This review was persuasive given the brief glimpse of the frequency response he shows:
Any thoughts on DMS review?
I find I don't mind listing to the Closed X (Drop) flat and a little bit of EQ improves that more. From the frequency response in the video, both the Aeon 2 Closed and Noire should be better, with the Noire seeming to be the better of the two. A lot of folks seem to dislike the treble of the Aeon's. I don't use any of the bads and I find the treble a bit understated compared to my Sundaras (using Oratory 1990 EQ, not the AutoEQ version). So, I doubt I'll mind the Noires. There is an Oratory 1990 EQ specifically for the Noires. It increases the overall treble by 3db while pulling down a couple of peaks. The area I find that needs to be shelfed down is around 14 kHz, the airiness. So, I do this with EQ rather than the insertion pads.
I received my Aeon 2 Noires today. My, oh my...
Compared to the Drop DCA Aeon Closed X, which are pleasing, the Noires are a dramatically better experience.
Without EQ (e.g., EQ is flat) using the Qudelix 5K with balanced cables the sound is much more compelling. Bass is punchy, mids are convincingly realistic, trebles are realistic without sibilance. Sound stage is wider than the Drop; instrument differentiation of the Drop is good already and its hard to tell how much better the Noires are--certainly some but there isn't a lot of room for improvement; dynamics overall are terrific. "Flat" is certainly satisfying enough to use as is, but benefits from some help. The bump at 100 hz is a bit too heavy so bringing it down 4 dB leaves plenty of punch left. The airiness above 14 khz can be tamed by bringing it down by 4db with a Q of 0.7. That's enough to make a positive experience even better. But, wait... ...there's more....
I have applied the Oratory 1990 EQ for the Aeon 2 Noire. I am using the Oratory hand-tuned EQ rather than the version from AutoEQ. This tames the upper bass hump, the airiness and corrects 6 bumps in the mids and treble all with corrections less than 4db. Depending on the specific music track these corrections aren't huge. Oratory designs the EQ with a combination of shelves and peaks that allows for specific personal changes. I reduced his increase of sub-bass and adapted the other bass changes to scale. This is really just delightful.
The headphone is much more alive than the Drop. It's more like the Sundara, but closed of course, and more nicely filled in at the bass range than Sundara (2020 pads) with Oratory's hand-tuned EQ.
