New owner of an Ether 2 and give some initial impressions after about 1 week of running them. I had Grado RS2e, a very different headphone (dynamic vs. planar, $500 vs $2K), I know. When I was shopping around I was looking for a comparison of those two and could not find it, so provide the Grado RS2e vs. Dan Clark Ether 2 comparison here. I'm not terribly experienced with headphones; so take with some grain of salt. Possibly look at the glass is half full. Details:
Grado RS2e with Beautiful Audio upgraded pads and leather headband.
Dan Clark Ether 2 with standard pad and also the large pads for the electrostatic VOCE, 1/4" jack 10" cable.
Woo WA6 SE 2nd gen with Western Electric 422 rectifier, and assorted 13XX7 power tubes, best so far with 13EM7
Sources FLAC files from iPhone/computer to Rotel 1572 integrated amp w/DAC, TT: VPI Super Prime Scout with Soundsmith Zephyr MIMC* and Vincent PHO 701 with Brimar 12AU7 tube.
I briefly tried the standard pads, but they made my ears rather hot, so almost immediately switched them for the VOCE pads. Still quite a bit warmer than the Grados. I consider putting some cloth liner onto the skin contact area. Unfortunately, the VOCE pads did not come with the adhesive film. Too bad Dan Clark did not contact me when filling the order, whether I had missed on this necessary item. I used some other double sticky tape as a stop-gap measure, but will get the proper adhesive film shortly. Wear comfort is excellent, can wear them without fatigue for hours at a time, and that was an important selling point for me.
I have a pretty big head, and side pressure is possibly a bit more than ideal. Not sure whether the metal suspension wires can be bent to alleviate that a bit. Any experiences?
There are some reviews that suggest noise problems with glasses, which does not apply in my case. Stubble beard is also no problem. With the larger pads, changing the position of drivers relative to ears makes quite a difference to tonality. I was first skeptical about that audiophile "snake oil" statement, but can confirm it.
Driveability is surprisingly harder for the Ether 2 at 16 Ohm, vs the Grado at 32 Ohm. I have to turn up the volume on the WA6 SE from a bit past 9 o'clock to almost noon, so about 80% more, at half the impedance. I tried to find info on SPL, but no hard data available (RS2e 99.8 db by Grado, guessed at 92–94 db here:
https://headfonics.com/2019/02/mrspeakers-ether-2-review/2/). That seems to be about right as 6 db ~ factor 4 (double volume at half impedance).
Power tubes also make quite a difference with the 13FD7 requiring higher volume setting than the 13EM7.
I was very concerned about rolled-off treble, as I thought the Grado's sounded sort of dull compared to my speakers (B&W CM6) after TT upgrade. Out of the box, my fears seems to have been justified, but after 50-70 hour of running them (yes overnight on streaming), they opened up considerably. What is immediately noticeable is the much better detail of the Ether 2 compared to the Grado. Soundstaging is also WAY better. A few records I have known for a long time made me literally jump because of unheard dimensionality (e.g. Siouxsie and the Banshees 92 degrees). Some synth/darkwave with effects are also much more vivid (Zanias, Keluar). Some inherently more mids-heavy indie/garage music sounds still detailed but a bit bloated (My Dad Is Dead, Salem 66 on Homestead Records).
Tube rolling on the Woo WA6 SE makes a difference. With the Grados, I could not hear any difference between 13xx7 power tubes (lots of difference between the rather bargain basement stock rectifier tube and the WE422). With the Ether 2, I can hear much more of a tube signature, and finally get a bit more the allure of tube rolling. Ordered some other rectifiers for the Woo and a Telefunken 12AU7 for the PHO 701 phono stage. Lots of fun ahead during the continuing lock-down. I still think the Ether 2 does not have enough treble response, but hope I can get at it with changes in tubes.
Bottom line, major bonus points on detail, 3D staging, comfort. Tonality: cautiously optimistic. More burn-in and tube rolling may address some of the issues. And maybe also my ears will re-calibrate.
