I have been feeding the combo music using an old Philips DVD player since and they have logged a tad over 255 hours in addition to the 20 hours of burn-in at the factory in China. During the 255 I fed different types of music and I varied the volume from very low listening to about Noon on the volume control (could be heard across room and sometimes in the living room). I did listen to them on and off during the burn-in and there was change (small as compare to other headphones) from start to finish but I found it very hard to hear any difference from day to day. Today I moved the unit to the main rack and it is being fed apple lossless files from my Dell PC using a Chaintech AV710 via an optical cable from Blue Jean Cable. The DAC is a Monarchy NM24 powered via a Monarchy Audio AC Re-generator and the IC are SILVER SONIC BL-1 I got on sale from Moon Audio via Audiogon.

The headphone is indeed very comfortable and the EF5 in low gain has plenty of power to drive the HE5. I find I have the volume at about 8 o'clock and that is plenty loud for me. Before I get into the sound I will describe a couple of minor issues I have with the rig.

1. The single ended cable is too short, IMO it should be at least 3 meters long. I have spoken about this with Fang and he indicated that after the Chinese new year they will be offering a longer cable and a balanced one. If this becomes a reality it will be a nice additions. BTW the stock cable is flexible enough and I like the red dot on the termination (headphone end) to help old farts like me with poor eyesight.

2. The hard plastic feet used on both the amp and psu are abysmal. The amp is way to close to the surface below and it transfers a lot of heat, plus by not having an air space the amp retains some of the heat instead of getting read of it. I would suggest placing rubber feet which provide at least a 1/2" or 5/8" of air gap. Besides a rubber feet will assist in preventing the amp from sliding when you attempt to insert the 1/4" plug.

3. Place small rubber grommets on all of the 4 screws on the plexiglass cover. This grommets would create an air gap which would assist in ventilating the amp, which like the EF1 gets quite warm.

4. Ditch the "tube protection" it IMO detracts from the amp, makes swapping tubes harder than it should, and retains heat.

As you can see in ergonomics my four "issues" are quite minimal and with the exception of the longer cable are quite easy to DIY a solution.

For sound impressions I will adding them to this thread as time goes on. It will not be a review but more of thoughts and ideas as a result of the music (mostly jazz) I listen too. For now I can say:

1. I do not hear any shrillness metallic sound in the top end as some have reported. It is energetic and it has a great extension but what I hear is clean and detailed. BTW, being 51 YO may be the reason I do not hear some of the treble issues reported by the younger listeners.
2. Bass is strong and like the treble it extends low. The low mids are very detailed as well and I do not hear any muddiness.
3. The mids are clear with long decay to the notes. Very easy to hear when a note starts/ends, the hi-hat sounds fantastic like it is being played in front of you.
4. I find the overall sound very life like with a fast presentation.

Based on the four bullets above you may think I really like the combo. The truth is the jury is still out. For some reason I do not find the combo as involving as the K501, RS-1, or the MarkL modded Denons. The individual elements of the presentation are extremely good, yet the sum of the parts do not bring to my face the smile the other cans do. Perhaps additional burn-in is needed, or I need to get used to their presentation.

I do want to like the combo because at times I can hear great sounds from it. But if it remain un-involving then I will have to re-think if I keep them or not. On a side note my wife who has excellent hearing really liked the combo and preferred to the MarkL modded Denons. More to come after I log another 50 to 150 hours of additional burn-in.
Great analysis! Thank you. Have you tried it on another amp?

This makes them tuned, IMO, for a fun sound. My HD-800s sound mid-forward in comparison. Ideally, I'd wish for them to be a tiny bit more flat tonally.
This is where I think the combo of uDAC > EF5 driving the HE-5 really helps complete the sound, as it fills in the mids but doesn't very lose much of the detail and soundstage of the more costly rigs. Although with my other rigs I don't think the mids are too recessed, and the detail and soundstage is even further expanded. If you want to hear real recessed mids, try a Proline 2500, SR-Lambda Pro or V3 Darth Beyer shallow cups.

I have continued to burn-in the EF5/HE5 combo, if I count the 20 hours done in China the combo currently has 300 hours of total burn-in. It may be my ears are lying to me but based on the changes in the last 25 hours I believe this combo needs more than 200 or even 250 hours of burn-in. I will post additional thoughts at the 350 and 400 hour mark which should be about another week of on/off use. Cheers.

I'll get a taste of this soon as I have both an EF5 and a uDAC incoming.

Hey fellow head-fiers, forgive me if this question is already raised.

I'm tempted with this headphone and this would be my first attempt into electrostatics. My current set-up is an old Sony CDP-X77ES feed into the modded Valab NOS Dac, Linn Akurate DS and a WA6SE. I like this combo very much no matter with the NOS DAC or from the high-res Akurate DS with the WA6SE (modded also).

And my question is, the WA6SE is good enough to drive the HE-5 or not, does anyone try to drive the HE-5 with WA6SE and would you please share your impression?

Your valuable opnions would help me to pull the trigger to grab the HE-5 or not, thanks in advance.

No it wouldn't because the HE5 isn't an electrostatic headphone.

Hi mypasswordis, thanks for your info, please correct me if anythiny I'm wrongly understand and what is the different of actually between a planar and an electrostatics? Thanks again.

Electrostatic uses charged stators (bias) on each side of the diaphragm, and a suspended mylar diaphragm between the stators that moves as the music signal passes through the stators.

Planar magnetic uses a diaphragm with impregnated voice coil sandwiched and suspended between two flat magnets (with holes for sound passage) and the diaphragm moves as the audio signal is passed through the voice coil.

Orthodynamic = diaphragm between 2 permanent magnets and can be driven by normal headphone amps

Electrostatic = diaphragm between 2 metal plates that require a specialized amp to generate an electrical field in order to move the diaphragm.

I found a solution: I balanced them. My amp is a different beast balanced, the result being that the peakiness has mellowed a tad, if they still retain the character I described before. They are now (pending a full cruise through a variety of music) closer to ideal. I was going to do musical chairs with my cables, putting the APS v3 on the HD-800s and my CryoParts OCCC on the HE-5s but I'll need to mod the connectors. I just gave in and re-terminated the stock cable and the result is pretty good.

Thanks for the correction HeadphoneAddict & somestranger.

But, does anyone try to dive the HE-5 with WA6SE and is it a good combo? Also, I'm going to order a Phonitor for the New year gift for myself, what you guys think these two amps for the HE-5?
post #1077 of 1668
Just placed my order, now the wait begins!!Still unsure about my amplification needs (current amp ec/ss), but i'll cross that bridge when i get there.Cant wait!!!!!!

Yes, Roc also takes better control of them when balanced. Snappier and more authoritative. Really good match.

This initial "edginesssss" change for the better after 200-250 hours.

I'm just lovin' these HE5 cans. Beautifully articulated midrange and transparency throughout the entire frequency range. And the deep bass almost vibrates your skull. Yeah...clear, open powerful and articulate. Makes the HD800 sound rather distant and lethargic.

The HE-5 seem to get less peaky over about 100 hours, and then I noticed no change. When I owned an EF1, it suddenly sounded much better after the 200ish hour mark so your observations sound accurate.

Gah, I am getting very impatient wanting to listen to the EF-5. USPS has been holding onto it for the past TEN DAYS (7 business) and made a delivery attempt on Sunday when I decide to sleep into the afternoon, ugh.
