    Hifiman Sundara (HE400i upgraded, around $500)

    Yes, on my first Sundara, the right driver intermittently cuts out. I think if you get a good pair, it'll likely last a long while; but even then, it may still be a bit risky, based on some of these posts. Such is Hifiman. Such is Sundara. Never had any issues with Hifiman's older generation...

    Hifiman Sundara (HE400i upgraded, around $500)

    The SINAD for this thing is definitely not great. I don't think there's a single class D amp that measures well. I don't think there's a single tube, or hybrid amp that measures well, especially compared to the cleanest measuring class AB amps, of which the THX789 is among the top-3 cleanest...

    Hifiman Sundara (HE400i upgraded, around $500)

    There's a bit of oversimplification here, and the technical subject, though relatively rudimentary from a physics/engineering point of view, is still rather complex for the average person. I didn't finish my EE degree, but did ace all of my physics, chemistry, and math courses in community...

    I appreciate the back and forward. These discussions are interesting to me. However, it seems to me based on past and current exchanges between us on this topic that in your view the progress of the discussion is dependent on how much your views have moved mines. I think this expectation may...

    Hifiman Sundara (HE400i upgraded, around $500)

    I think you're conflating driver resonant frequency with resonant frequency of the entire headphone assembly, which I'm not sure is even high enough to measure. Simply, my Sundara's whole unit vibrates simply because there's not enough clamp force to dampen the vibration—and I prefer it this...

    Hifiman Sundara (HE400i upgraded, around $500)

    The left driver died from a subbass test track. The right driver was from the 30hz sine test (to be sure it wasn't just one driver that was faulty). The EQ was only on during the test track, not the sines. Let me tell you, the Sundara's driver assemblies can vibrate like crazy from mega bass...

    Hifiman Sundara (HE400i upgraded, around $500)

    Happy to have contributed to your newfound sonic pleasure. Not all planars scale up in the same way, oddly enough. When I went from my THX789 in balanced mode to my XLS 1502, the HE-6se didn't really transform much at all. It was a significant, but not mind-blowing improvement. And then, my 6se...

    Don't have experience with the A-100, but my recommendation is to go even further if you can. Try something that could output 300+ wpc into 4 ohms. Take extra precautions if your amp is class A, B, or AB. You can easily destroy headphones with these amps, though planars are less susceptible...

    Hifiman Sundara (HE400i upgraded, around $500)

    Time to revisit my review from many moons ago. I wrote that I'm often hesitant to start listening to music through my Sundara +Crown XLS 1502 combo because once I start, I literally find it very hard to stop. I wasn't exaggerating. It is still true to this day. I often find myself staring at my...

    Feedback by 'tigon_ridge' on listing 'Drop THX 789'

    Sup27606 purchased a THX 789 from me, and the communication between us was pleasant all the way through. Glad this amp has a new, good owner.

    Hifiman Sundara (HE400i upgraded, around $500)

    Hifiman seems to do a lot of ninja revisions, so there's an issue with consistency. When I measured the load of my Sundara, it was 39 ohms, a decent amount over the advertised 32. I also have another pair, my first one, but haven't measured that one. My first Sundara had the pivot screws glued...

    Hifiman Sundara (HE400i upgraded, around $500)

    Keep in mind, the Sundara does have a low end roll off. My EQ does add more subbass than is true linear response, sure, but mostly it's just to offset the Sundara's roll off. At 30hz, it's more like +3db than +6db, and at 20hz, +4db, if the roll off is accounted for. Regardless, frequencies...

    Hifiman Sundara (HE400i upgraded, around $500)

    It's mostly subbass, and information below 15hz is virtually nonexistent in 98% of any audio content anyway, even very bassy tracks. The midbass increase is barely there. At 80hz, for example, there's only a 3db increase in the second setting. At 100hz, you can hardly hear a difference...

    I'm still not sure if it's the amount or quality of power. Many people have also said the HE-6se shines with power, but I've not found that to be the case.

    https://www.head-fi.org/threads/hifiman-sundara-he400i-upgraded-around-500.860413/page-263#post-17181116 I'm not about to recommend anyone buy a Crown XLS 1502 just to pair with their Sundara, but if they are crazy enough to do it, they'd be well rewarded with one of the best pairings they'll...

    Hifiman Sundara (HE400i upgraded, around $500)

    The Atom is basically a mini THX 789, minus the balanced output. In balanced mode, I believe the THX 789 can output almost x4 more power than the Atom (unless the Atom has been updated) through the Sundara, and x6 max if the load (headphones) has low enough resistance. Yet, I'd managed to clip...

    No scratches or dents anywhere. Both the balanced and single-ended outputs work. All three gain modes work. Both single-ended and XLR inputs work. The bypass switch works. Everything works. I've used this amp for everything from sensitive IEMs to inefficient planar headphones. Probably has the...

    There needs no resolution, because to me there was no conflict...at least until I felt your tone getting somewhat impatient. I don't know why you think that I was trying to persuade you into thinking one way or another about either the Sundara, or the HE-6se. I was just giving my opinions of...

    Hifiman HE6-SE

    I don't know why you're doing this. You came to the Sundara thread to compare it to the 6se, which makes sense, but you did it with a rather contentious/defensive tone, and then now you're pulling me over to this thread to resume the discussion. I'm not going to bounce back-and-forth between two...

    Hifiman Sundara (HE400i upgraded, around $500)

    I think a lot of people are hesitant to post their opinions, if they think that their opinions would be very unpopular. Hence, you wouldn't often see people posting anything about the Sundara in a summit fi thread. First of all, I had to go through great lengths just to get what I've always...

    Hifiman Sundara (HE400i upgraded, around $500)

    I powered the HE-6se with a speaker amp that is capable of outputting about 25W (guestimated) into 50ohm, which is the HE-6se. It's the same amp that I'm using to power my Sundara, though I'm using it mostly for sound quality reasons than power, although the power headroom is nice to have when I...

    Hifiman Sundara (HE400i upgraded, around $500)

    The vast majority of reviews of the Sundara I've read agrees with my own experience about its excellent treble. I didn't feel there was much difference in the quality of treble between the two headphones. The 6se may have a slightly drier treble, but that's about it. All of this is post-EQ. I...

    Hifiman Sundara (HE400i upgraded, around $500)

    I'm 99% certain that a faulty 6se was not the case, because: 1. it happened to both drivers, 2. the math checks out. There is no way any headphone could withstand 44+ watts, which is what the 6se would need to match the max output of the Sundara @ 4W. I think the 6se v1 crapped out at around...
