HE-5..initial musings - Page 105

post #1561 of 1668
Referring to my previous post in this thread, where I said the phones (with around 15Hrs on them) was killing me with its sibilance, now it's close to 85th mark, but that annoying sibilance still persists.

As said, I'm very sensitive to sibilance and the amount produced by these phones makes me want to let them go. I tried them with all amps I have, including the EF5, the one that's designed to match these phones, but none could deliver relaxed, strain-free sound. I tried a number of upgrades/improvements e.g. replacing the OpAmp in the buffer state with a discrete OpAmp (Audio-gd's Moon), using Tube Damper (Herbie's UltraSonic), and replacing a stock fuse with an audiophile fuse (HifiTuning), but none of the above did the trick (not to mention replacing a stock power cord with an "audiophile grade" one, which is connected to a high quality power conditioner).

I now find it easier to listen to my K702+BlueDragon. I don't know if it's just me, but I feel that HE-5's sibilance irritates me way more than that of K702.

They could be a perfect pair of headphones for me if I can find some ways to tame the high. I may bear with them for another 200Hrs, and try a replacement cable from APureSound (already ordered), and if the situation doesn't improve to the satisfactory level, they will have to go.

FIY, mine is the "new version" (beta 2, if you will) with extra damping.

recabling should help a bit, but that is extra a couple hundered bucks. Mundrof silver/Gold wire could be a good fit.

I don't have the "highs" problem, but if you are looking to tame them a bit, anything with silver in it, might not be a good alternative. Plus, these phones are pretty fast, and silver will make them faster, which could be a dramatic change.

When a bunch of us had problems with our Qualias being too sharp (because of the insane amount of detail), Dru came out with the Dragons and it was a match made in heaven.

Mundorf S/G does not have the typical silver sound. It is very flat and even sounding, very warm. The usual complain is that the bass is not very punchy (but very good bass details). The sound is softer than the usual OFC copper wire (which I found a bit congested).

On the other hand the S/G is very expensive and if you go for quad-braid (per side) you are looking at 4 wires per side, 8 wires stereo, a 6 ft cable will use up almost 50' of wire, considering the usual price is over $4 per ft (one source is partsconnexion, strangely they don't offer any quantity discount) that is over $200 just on the wire. And that is if you DIY. And for some a 6' cable is not quite long enough.....

I was interested in the HE5 mainly as the replacement for my 990/600 (which is my bass-head phone), now I know the HE5 won't have the kind of wooph I am looking for. Thanks Shahrose and Skylab for the HE5 vs. Beyer info.

I think mine were the beginning of the new version, they seem to have the "star" cutout anyways, and they were the same: great but barely tolerable as far as treble "brightness" goes. I think one listener's "sibilance" may be another's "sharpness", but I digress.

If you can give them that extra 200 or so hours, you will be rewarded greatly IMO as it took a good 200-250 hours for mine to smooth out. The difference was really profound in my case.

My advice is to bear with them

When did you buy yours? My first pair that I bought in November had the star cutout and was part of a new batch after being out of stock for two weeks, so that was probably when the new version started.

I second that.

It takes cca. 250 hours of medium to loud burn-in to settle that annoying sssssibilanccccce. After 600+ hours on mine, a reminder of pronounced esses and "wild" hi-hat happens only on badly mastered records that are also bright with other phones too.

Thanks for the advice guys.

I of course have no problem holding on to it for another 200, 300, or even 500 hours, if they really need that many hours before they perform at their best (another K701/2 anyone?). It's good to know that there's some light at the end of the tunnel.

About the cable, I've just ordered one from APureSound. From the description on the site, it's a copper cored silver cable. Does anyone have any experience with this one? If not, I may post my impression after receiving it.

I may also try using the Golden Reference with this phones (currently using HGA DNA), as the Cardas sounds warmer than the DNA.

I think the burn-in figure is starting to get a bit ridiculous. I found no changes after 60-70 hours of fairly high volume pink noise/bass-sweep burn-in.

...and I believe you.

But my specimen had under 20 hours of "factory pre-burn-in" while some have 200.

It is indeed very strange that people are experiencing "sibilance" on their HE-5's. I let my friend try the HE-5's out and he is super sensitive to sibilance, coming from the HD-650's, and he said it is not in the least sibilant... I am sure lots of people know the song "Paranoid Android", well I remember with my K701's the song was very uncomfortable, very edgy, metallic sounding and noticeable sibilance, though on the HE-5's, it was almost completely gone... That is why this baffles me so much...

Mine had 20 as well. I'm a firm believer in burn/break-in but IME the psychoacoustic adjustment produces the larger effect of the two. I had about 500 hours on my pair before I sold them and they sounded exactly the same as they did at 70 hours.

a bit OT:

Does HiFiMan have any plan on making a mid-grade large-scale-mass-production ortho? Maybe around the YH-2 size with similar power requirements? Priced in the $200~$250 range to rival mid-grade phones such as HD650 and 701?

Just curious.

Would be awesome but I doubt it. They will probably milk the 600$ orthos for a while because they are one of the only in production... Audeze hasn't even released theirs yet... if the HE-5 keep selling well I think they will have a lack of motivation which is silly because they'd be missing a business opportunity.

Mine were purchased from the Head-Direct site in the second week of December; they arrived on New Year's Eve.

I remember that, I think it was the first batch that got the 200, then the later ones just got the 20, and that speaks directly to actual mechanical burn-in...

Vs. the "psychoacoustic adjustment" spoken of here, which can't be discounted either, IMHO.

Couldn't the combination of both mechanisms account for the longer-than-average "burn time"?
