Checking around a bit (these specs don't seem to appear on the official website it), it seems they have an output impedance of 15 ohm, which is high for planars considering their usual low impedance and the 1:8 ratio for output : input impedance that is generally recommended, and a power rating...

I had the Sundaras, but I didn't like the headband: they never felt comfortable to me. I have not tried them side -by-side, but I can say the HE-6SE is the best headphone I have heard, clearly beating the Elex (which some consider the next step after the Sundara) and the HE-560 (which seem to be...

I've been switching between my two main (and new) headphones for a bit, and I thought I'd post my comparison of the two: Hifiman HE-6SE V2 vs Focal Elex I'm using high/resolution Progressive Rock music files for this comparison (24/96 and 24/192), as well as some High-Res and some vinyl rips of...

Oh, the A90 has plenty enough power to power the HE-6Se. The impacts are there, and well defined. I was simply comparing it to a headphone that is ALL impact. The HE-560 V4 brings up the drums in the mix, to the point that it can be obnoxious at times. And, while it may have MORE impacts, the...

Well, I broke down and ordered.... a HE-560. But then, the HE-6SE deal came back, and I was real interested... So I ordered one too! First impressions: very good, but I felt there was some confusion in the upper range, something holding it back. I tried without the grills, and the treble...

Done a few days back: https://www.head-fi.org/threads/avantone-pro-planer.941951/post-16011502

All the screws were well tightened, there was no change in sound signature.

Uh. Going to try that tonight. It seemed to me, during my last comparison, that the Planar was more congested than usual, which I assumed it was due to the comparison to electrostats.

I've already done so here: https://www.head-fi.org/threads/avantone-pro-planer.941951/post-16004702 I guess using the white tuning felt would get you a more neutral sound vs the black felt, but I feel it kills the transient response, making the headphone a bit boring to listen to. EDIT: If...

I'm especially interested in reading comparison against the Sundara, since I own it. Is that new headband more comfortable than the Sundara's strap?

Really curious to hear some impressions about these. I hesitated between these and the Elex, and I ended up ordering the Elex instead, for a couple of reasons (I had the Sundara already, I lacked a good dynamic headphone, and Adorama charged $50 or so for shipping to Canada).

And the rest of the gang: the Mr Speakers Aeon Flow Closed Re-tuned, my good old Audez'e LCD-2, and my new chain: the Soncoz LA-QXD1 driving my Topping A90.

The Sundara, KOSS ESP/95x, the Avantone Planar and my good old Gamma 2 DAC

Well guys, last one. I'm sending them back Thursday. I've made one change on chain: the Soncoz LA-QXD1 has replaced my hand-soldered Gamma2 DAC, and it's a very strong improvement for my high-resolution files! Avantone Planar vs Koss ESP/95x (with Vesper hybrid pads) - SOUNDSTAGE and IMAGING...

Avantone Planar vs Audeze LCD-2 (pre-fazor) - BASS: if there is one thing the LCD-2 was known for, back in the day when it had just been released, it's the quality and extension of its bass. The Planar comes very close, but the LCD-2 has it beaten here. - VOCALS : the LCD-2 presents vocals...

Well, let's finish this! Avantone Planar vs Dan Clark Audio (Mr. Speakers) Aeon Flow Closed Re-tuned (black felt filter) - ATTACK: the AFC has stronger transients it seems: I can clearly hear the pluck of string and the strikes on the drums. - TREBLE: AFC has slightly clearer highs. - COMFORT...

I was also looking at the HE-6SE from Adorama, but frankly, I have enough Planars for the moment and I wanted a nice Dynamic headpone.

Man, that sucks, hope you can get a reimbursement. Well, that settles it for me. I'll be testing against my old LCD-2, then I'll return them. They have a nice, balanced sound, but they will break sooner or later: that metal piece holding the strap is so flimsy it's ridiculous! Elex already...

Oh, BTW, after this test, I've more or less decided to return the Planar. The build problems are a major concern, and with their original pads, the Sundara once again sounds mighty fine! I'll continue the comparisons until then. If Avantone release a version 2, I'll be interested in checking...

Yeah, I also tried my hand at using EQ, but I always go back to the unaltered sound after a while. In other news, I'm feeling a lot better, so let's have another go at it! Avantone Planar vs Hifiman Sundara (original pads) Well, this is much better than the Dekoni Pads! I never really have...

I would say it is remarkably close to the LCD-2C (I assume it's C for Classic, or is it C for Closed?), but with less peaks and valleys. https://headphonedatabase.com/oratory?ids=141,68

Got a cold, won't continue the reviews today. I tried the original pads, and yes, the clamp force does go down and the treble is slightly tamer, but then balance is still tilted towards the highs. At the moment, due to my condition probably, I cannot stand listening to the Sundara more than a...

Well, it really sucks that the build quality is so lousy on these.I don't have any issue on mine (#17), but I'll keep watching them. Luckily, I got them from a local dealer, so I can get a reimbursement or a replacement pair easily enough if something happens... I hope. Well then, let's...

I have the 2020 version. I bought it during the summer. I do have Dekoni pads on these (hybrids), so I will test with the Dekoni and with the original pads. It appears to follow the Harmon Curve very well. However, that curve is a preference curve, not necessarily what everyone perceives as...

Well, it's the next one I intend to do, though from memory I probably won't come out with the same conclusions as yours. Hopefully I'll have time tonight.
