Hifiman HE-300 mod removes the dark sound - Page 5

post #61 of 84

I wonder if Hifiman made these ports for the end user to mod the sound or for their guys to experiment with and get their signature. Either way, it's a nifty thing they did.

Do you feel that yours are bass emphasized with Velour pads?

Here are my thoughts on the Modi/Vali stack with the HE-300: http://www.head-fi.org/t/685162/new-vali-schiit-amp/2205#post_10061565

You ought to give that Vali at least 72-100 hours before making a conclusion with the he300. Might also want to consider a better source than an ipod.

If it's true that iPods are relatively dark, then you've got a super dark setup from source to a warm tube to a warm hp. I think a Magni may be a better match for the 300s but I would improve your source first. Maybe computer to a Modi?

This may be a bit contrary to the norm but based on your impressions of the vali and he-300 combo I think it may be exactly what in looking for. Im sure I'm in the minority here but I find my he-300's to still be just a hair brighter than I like even in stock configuration. Granted they aren't sibilant or obnoxious at all, I just wouldn't mind even more warmth in the treble. I really do tend to like darker highs in general. That said I still feel that with the right recording they sound incredibly good with the felt removed. I'm definitely torn on amps though. I may still go for the Asgard 2 or matrix m stage in the end since it would probably work better with more headphones and the preamp option would be wonderful for my speakers. I want to get and mod a pair of t50rp's next and I'm concerned the vali wouldn't be ideal for the lower impedance cans.

I am using the Modi with my Mac mini. I'm going to let it burn in and try a few other configurations with the mod and see if anything changes.

I got in on the black Friday HE-300 deal direct from HeadDirect. When I first tried them out, the imaging seemed all messed up, but after about 10 hours of use, they now have settled in very nicely.

 

QNAP TS-120 NAS (all FLAC rips) > Logitech Squeezebox Touch (optical) > Bifrost > LD MkII preamp (all Russian tubes) > Emotiva Mini X

 

I gave it a try with the removed felt as suggested here, but it was just a bit too harsh for my liking. So the felt is back in place but I switched pads. I am now using Beyer pads from DT-990 600 ohm with HE-300 and the result is great. Better for me than the velours or pleathers.

 

Driving the HE-300 with an Emotiva Mini X is quite impressive. The noise floor is there, but very tolerable. Will fix that later.

Do the dt990 pads need altering or they just go over the plastic snap piece?

Good to hear! Did you have to do any mods for the DT990 pads?

 

I've been doing more critical listening with the Modi/Vali stack and let my brain burn in a little bit. I have to say I'm really enjoying them. This combo is almost good enough to give me goosebumps. One great thing about this combo, I haven't had a bit of fatigue even with the felt removed. I'm becoming more and more impressed with every listen.

Taking 2 things out of Hifimans playbook, here's what I believe is a true in-between sound with more tuning options. You can do this with the stock felt, as my microfiber has a close sound to stock, or you can go with a lighter felt and less holes.

Take the felt out of the driver or if you're brave take a blade and cut the felt on the driver. I do not recommend doing that but it's possible and could save some time. If you do take the felt off first, you could use a hole puncher to have a cleaner opening. Start with the center and cut a hole hole for the very center hole on the multiple opening behind the felt. This should free up some treble and might be what you want if you prefer to keep most of the dark. If it's still not enough treble, cut a hole or two more. I would stop at 5 or 6 holes as more would probably be close to just fully taking the felt completely off.

As of right now I have the center and 4 holes uncovered with the microfiber and it's a perfect in-between sound to me. Poorly recorded or bad mp3s get too bright on some tracks but with the good tracks it's perfect. There is also a bass back-port on the plastic that is covered by the felt. It's circled in the picture I posted a page or two back, I recommend keeping that port covered as the bass impact benefits from it.

I've decided to put a FS and more like an interest check with willingness to sell if anyone missed on the Black Friday deal. Ad is on my signature below but for those on mobile its: http://www.head-fi.org/t/696507/fs-ic-like-new-hifiman-he300

Got any pictures of them with the Alpha Pads on.   Thanks OOK

Sorry, no, I don't.   After listening to them for a while I decided they weren't quite what I was looking for.  I tried tuning them with various combinations of opening/closing the baffle ports, damping materials, etc, and just wasn't happy with them.   I have since pulled the drivers and am experimenting with running them closed.   I picked up a cheap pair of Monoprice cans to transplant into since they also use 50mm drivers and have had good luck with the sound (also using Alpha pads)   My next step is to find a donor pair of better quality closed cans to transplant them into or try to build some closed cups for the HE-300 headband/yokes.

My computer is using HQPlayer to send DSD files (including PCM files converted on-the-fly to DSD) to the Schiit Loki DAC, then the Vali amp, and on to my HE-300s.  Like many posters, I consider the HE-300s to be a major bargain at $150.  I ran everything in stock configuration for a few weeks and liked the setup just fine.

 

Then I read about this mod, removing the felt.  I did it.  When I examined the felt, I certainly theorized that removing it would be a good thing.  Earlier posts to the effect of "No one would ever make speaker grills from this stuff" seemed spot-on to me.

 

I plugged everything back in and fired it up.  The results were severely disappointing.  I spent many hours listening and my initial inpressions were borne out - unwelcome sibilance, excess brightness and harshness.  I found listening sessions substantially more fatiguing, much more quickly.  Nevertheless, I ran this set-up for nearly a month, listening for hours every day.

 

Now I've put the felt back in.  The harshness is gone.  I can listen for longer without tiring.  What's really odd is that I am satisfied with the volume knob turned up less when the felt is present.

 

Maybe my ears are weird.  Maybe I just prefer a much darker overall sound than most folks.  Maybe I listen to crappy music that's recorded harshly and the darkenss of this setup is euphonically camaflouging upstream problems.  However, I don't think so.  I have some beautifully recorded DSD files of classical music that I like better, too, with the 'phones in their stock configuration.

 

Whatever the reason, I found this mod to be severely counter-productive for me.
