I'm curious about the measurements as well.  Keep us posted.

I wonder if it might be time to finally check out Grados. Though I've always been under the impression that they're not suited for big heads like mine.

I'm in a similar boat as you (and also looking for a closed headphone) so I've decided to give the Mad Dogs a try.  I'll probably be picking it up in the next few weeks.

I am sometimes harsh on the objective/subjective line but lately have been fiddling with my car, and I am reminded how important a lot of non-audio aspects are to good sound. The door rattling may not show up in the measurements, but they will drive you nuts. I am just not willing to knife up my pads for hope of a better sound without some "proof" that an impact will be made. I have similar ambivalence toward buying tons of dynamat for my car in the expectation that it will really be more quiet. In some cases, sure. In others, what a waste.

 

Also, the velours are just good to my ears - better than the pleather despite only making a fairly slight measured change.

I hear ya brother, investing time and effort cutting into an untouched product is gonna give some people hesitation.

 

Purrin's measurements-to-come will consist of FR, CSD, and hopefully THD. The FR and CSD will show any relative shifts in frequency response compared to velours and ideally stock pleathers too. The CSD will in addition show the decay data, which may or may not be useful (as it cuts off around 500 Hz, and the plots of 500-1000Hz in waterfall tend to be a mess anyway). If THD is also measured, it could show how the harmonic distortion is laid out between the modded pads vs the 2 stock pads.

 

Another big consideration is the degree of sensitivity with measurements. Some of you might recall recent studies that showed that human hearing exceeds the sensitivity and complexity of the most advanced acoustic measurements, so even small changes in measurement could amplify to very drastic changes to the acute ear (case in point: purrin's HE400 velour vs pleather measurements, vs perceived differences).

 

These will all be done on his HE500s, of course. I think he got rid of his HE400s, but relative pad-based changes could be extrapolated.

Just an update: Head-direct is covering the damaged wires under their warranty and sending me new wires. Yay for good customer service!
post #8165 of 20386

I wonder whether I got a faulty pair or not..

 

I bought my pair around juli 2012 from head-direct, I've got the Version 2, I guess. I read somewhere that they've got an update d version, am I right? I'm saying this because I think mine isn't performing as it should.

 

I'm using velour pads on them, running through a fiio e11,LOD I ipod classic with 320 kbs mp3's (from what.cd). When I put the fiio at around '3' (slightly less), I hear this imperfection, high pitch or instruments are not smooth, like it's vibrating. It makes it appearance around '3' volume on the fiio, at around '2' it disappears.

 

So I'm wondering whether it's my source or the HE 400, I also get it at high levels wish my HD 25 's. I thought the 'imperfection' was due to HD25', not being high-end enough. So I thought the HE400 wouldn't show it, but it does. Reading through others reviews I haven't really seen anyone mention this. Maybe they uses a better source, or they used a new and better version or mine is faulty. Halp

What you described sounds like a piece of hair or dust particle stuck to the diaphragm surface. Take off the earpads and the grills, and scrutinize the driver membrane surfaces, also blow some wind on them to try to sweep out debris that might be hidden from sight.

 

Also could be something faulty with your audio chain; try the HE400s out of different amps / your PC etc instead around the same volume, and see if you can reproduce the thing.

Alright, I'll try and do that as soon as I can. The only amp I got though, is the fiio and the highest fidelity sound output I got is the iPod I guess (or my laptop; HP 8570w). I've got an exam this week and I'm moving to a new dorm. Will post back here 😉

post #8168 of 20386

So for the past week I was running the HE-400s out of a DAC only (no amp). Today I got my Fiio E12 which puts 850 mW at 32 ohms. I'm not noticing all that much change in the quality of the sound, but I am increasingly noticing the treble. The treble adds a lot of sibilance and sharpness to vocals and hi-hats and things like that. Sounds unclean, almost distorted. I'm not liking this sound and I think that may be the nail in the coffin for the HE-400s for me.

 

However, I noticed with the amp the sound responds a lot better to EQing. I bump the treble down through foobar2k -8 db or so from 10-20 khz and it sounds a lot better. Meh, not sure if that's enough to keep me with the 400s. 

 

So my setup as it stands:
 

PC --> Hifimediy Sabre 32 --> Fiio E12 --> HE-400s

Anybody knows how well does HE-400 work with Woo Audio WA6 ? I am deciding whether to buy Lyr or WA6 for HE-400 and HD650. Lyr should be great for both but I am not sure about HE-400 and WA6. Every info would be great ;)

I would go with the lyr. tongue.gif

post #8171 of 20386

Guys, I'm tempted to kinda skimp on the DAC/AMP on the HE-400 since I'm quite convinced that it will sound good from cheap stuff as well. I am really tempted to buy this DAC/AMP from HA info: http://www.ebay.co.uk/itm/190785547272?_trksid=p5197.c0.m619

 

Anyone got any idea on this please? Would really appreciate some feedback!

It definitely has more than enough power (700mW at 32Ohm), so sure, try it.

That's exactly how I am thinking. However, I am still a noob when it comes to hifi and know that power isn't everything to it which is why I am hesitant.

 

Do you think that the DAC in it will be sufficient as well? Thanks for the reply btw :)

Is there another way other than buy the connectors and make a DIY cable?

Thanks,

Can anyone help him? He's looking for a shorter aftermarket cable for the HE-400s. I'm not very knowledgeable about cables since I'm not much into it, so I can't help him myself.

 

Thanks.

Ooooh I just don't know what to get biggrin.gif My options - Lyr with Lorenz tubes which should be great would cost me 510$ , WA6 would be 600$.

 

After reading this :

 

"The Lyr with the HD 650 is indeed not bad... for the price. But going to the WA6 is truly a step above. 

 

Let me put it this way. Imagine the jump from E11 to Magni was about 100%.

 

The jump from Magni to Lyr will be about 80%. 

 

The jump from Lyr to WA6 will be a further 60%. "

 

I was like .. ok than, I'll find out how good WA6 is with HE-400 so I know it works well with both HD650/HE-400 and just get it.
