HE-5..initial musings - Page 43

post #631 of 1668
I will give it more time for sure but no headphone goes from quite sibilant to not sibilant from my experience.
It's tough, so many recording sound great but a lot are not listenable.

Fang,
I have some questions I sent earlier to you.
Can you address the lose nut within the housing and how to tighten it again? I feel there are going to be a lot of people having this issue.
Is there any explanation as to why there is a fairly wide gap of people hearing sibilance and others not hearing any? I can't believe it's just individual taste.

Then you haven't listened to a brand new HD800 and one that has been burned in for 600+ hours. I took my (600+ hrs) HD800 to a mini meet and compared it to an HD800 that had about 100 hours. Mine sounded quite a bit better and another head-fi member made the same comparison and thought the same.

Sure it does Whatever rocks your boat..am not saying it isn't a great headphone, it is and will be for a fair number of people. But to me it falls short for this one main reason. I had the headphone for 3 weeks and I had about 150 - 200 hours on them and it didn't change the sound signature one bit after the first 15 hours. YMMV of course.

Is crackling in an HE-5 an indicator of damage or simply an indicator of being underpowered?

i've listened to several pop/rock tracks that presents sibilance/etchiness on
my d7000 and is unbearable on the gs1000...on my he5, no sibilance. one thing
i can do on the he5, that i can't do on the d7000, is listen at relatively high
volumes without any spikes/hot spots. at this point, i don't know if there's a
variation in the he5 units or perhaps our setups.

my setup: onkyo dvs555 transport-vdc2/vac1 dac-wa6SE w/6sn7-he5

my he-5 don't have any sibilance compared to d7000s. and not a noticeable amount more then hd800s.

if the volume was at max or relatively high for an extended period, like all day,
then yes, i'd venture to guess that the crackling may do damage to the hp.
the crackling or clipping, as some would put it, is due to insufficient current
or too much current... most likely the former.

It would be very hard to destroy an ortho...it is unlike any dynamic headphone..the crackle u heard (still hearing?, describe it in detail please) could be due to an intermittent contact in the cabling or at worst could be something wrong with the diaphragm in which case only recourse would be to replace the headphone or that driver assembly..is it only on one channel or both?

It could also be related to clipping due to an underpowered amp..but i hardly doubt you could damage an ortho with a low powered amp again for the reason that it isn't a conventional driver design. I have had a few DC volts run through the headphones for a few seconds without any damage to my orthos (not suggesting you do/try that), but a dynamic driver would have probably been toast if I had done that.

It sounds sort of like a stiff plastic bag being crinkled(?) on both channels during loud passages. I think there is less of it on my SF Line3 than on the Marantz. I tried wiggling the cable and it doesn't produce any noise at all.

P.S. Loud is a relative term here, at this volume setting the SR225 would be hurting my ears already.

So playing around with the cable makes the noise go away? Sounds like a cold solder on the cable terminations to me.

My Head-F1 HF-2's had really bad sibilance (and wobbly bass) until 100 hours.
I know they are a dynamic headphone, but you still have film with conductors on them on the orthos that have to change over time. Whether good or bad, a tight piece of film is going to change after a certain amount of hours of stretching and reforming.

G08>Luxman P-1/Headroom Desktop max version with separate Power Supply/EF-5>HE-5 with 200 hours on them = no sibilance.


@tim3320070- I see in your sig, that you have a $12 balanced DIY Mogami cable. Have you gone back to the original cable to see if it yields different results?
When I changed my AES/EBU cable to Mogami from my Transporter to my Meitner DAC 6E...Whoa! Sibilance. Back to the Cardas.

HE-5 is very sensitive to amp and source. We have tested each HE-5 unit to make sure all HE-5 headphones are identical.
