    Not a lot of ringing despite Mt. Doom. Beyer must not have lied about extra damping this time around. Although something is going on at 2kHz plus distortion. Low-to-high midrange transition looks better than T1 2nd Gen.

    Indeed. There's a hot spot, but I found the Amiron more tolerable than the T2 Gen 2.

    T2 Gen 2 has the FR null which turns out of be ringing in the CSD. These tend to sound very piercing at 7.5kHz. Also, the T2 has other smaller spikes at 6.5kHz, 8kHz and 9.5kHz. T2 is like death from a one big nail and a thousand needles to the head.

    T2 Gen 2 CSD. The midrange to treble transition is more abrupt and less smooth compared to the Amiron.

    I'll run some different visualizations tomorrow.

    Thanks for these, I think there has been genuine curiosity- the Beyer shills have been doing backflips over them like they're the greatest thing ever. It's really nice to have someone take a proper look. I'm secretly hoping that they won't suck, given their midrange pricing- need a few more of those.

    The FR looks a lot less whacky than you'd expect, other than that epic 8k spike. I do wonder how it sounds in practise, with higher percussion and string harmonics. Looks like the damping actually works, this time, and driver matching is uncharacteristically competent for Beyer. What's going on with the distortion, around 2kHz?

    Looking forward to more detailed impressions of how all of this manifests in how they sound, possibly even driven from familiar and similarly "value" amps.

    Edit: More detailed impressions are available, cunningly hidden here:

    Here's my 2 cents. I honestly hated them.

    It looks like some kind of resonance. My guess is that the driver itself is well damped (no ringing at the 8kHz peak) but the cup is mostly untreated. Nothing new there.

    Haha. I snuck a peek in HF and just had to smile: The treble is so damn smooth you'd think you're drinking the finest craft beer.

    This is why I'm headed back to more objective analysis.

    And here we see the Beyerdynamic middle-finger region of the treble...

    Hahaha. I was wondering who was going to point that out.

    It still unfortunately looks like the same old Beyer tuning. They claim on their website they "completely eliminated annoying treble resonances." Sure doesn't look like it. I'm actually more turned off by the distortion than the sharp treble peak.

    At least no mid range dip like the DT1770.

    Why can't they get it right? I have owned DT770, 990, 1770, I really love their build quality and comfort, but the sound, ugh. 1770 was better than the 770, 990 had the worst treble. Might get sucked into Amiron too who knows, Beyers are widely available hard not to pick one up just for the heck of it.

    Never tried that one.When I was looking for an open back to move from DT770, got suggestions that 880 is too bright, jumped to 990 directly.

    DT770 and DT880 are sunlight bright. They burn. DT990 is supernova bright.

    I don't think there is a full size can brighter than a DT990 (or it's tesla driver derivatives).

    Strongly considering sending you a DT990 after this statement. LOL

    Yes I learned this the hard way (not that hard though, Beyers have surprisingly good resale value). My "hifi" journey started with 770 and 990 (non-tesla), no wonder I had to take a 2 year hiatus after that disappointment.

    Interestingly I ended up with a DT1770 for a while, just got rid of it yesterday because I discovered the Senn mid-range goodness. I absolutely love the build quality and the unassuming look of 1770, the sound is still meh, there's a V-shape, treble is better than the old 770 and 990 though.

    HA! It was too easy. =) Couldn't pass it up.

    I had a special comment reserved for this, but decided on the path of discretion vs vulgarity.

    Dude, I used to own one before I got my HD558 and HD600. Jebuz!

    I know u can do some great magic with the DT770s though.

    I also love the build quality of the Beyer full size cans. The sound though.

    Thanks for the measurements Marv. It's a step in the right direction but Beyer gonna Beyer I guess.
