post #9136 of 10212

I don't see why the DX80 can't drive the HE-400i well enough. They work out of normal portable devices (and were fine out of my Galaxy Note 3). They did sound better with a little more power, but it wasn't crucial. In the end though, maybe looking towards a used Schiit stack?

I just did a shootout with the Symth Realiser running a modded HE400i paired with a Class A 60w amp vs Stax SR007 MK1 paired with the SRM-727. This shootout was for one purpose only, to determine the best headphone for the job, action movies.

 

Stax epic fail on explosions and heavy material during actions scenes, distortion like there's no tomorrow, can hardly turn up the volume. Switched back over to the HE400i with all that juice from the 60w amp, blew the pants off of the Stax. I am sure the BSHE and the SR009 would be a better competitor, but at $10k I don't care much anyways. I would think any further improvements over the HE6 with a 300w amp would be marginal at any price point.

 

HE400i's were so much cleaner and more dynamic, I would say after the mods, as detailed as the Stax also. In stock form they were pretty lame, the 2.5mm connectors and material covering the grilles really holds them back.

 

Now to compare the HE6 with the HE1000 and keep the winner, me love them long time :)

Interesting findings, can you tell us what mods you made with your 400i and what specific amp you were using it with?

Removed the 2.5mm connectors, hardwired a new thicker wire cable, terminated with spade connectors for easy removal. This had to be done, as the cable coming from the drivers is only short and if you solder a new cable, change your mind and need to cut again, eventually you will be left with nothing. On the other end I have the wires soldered to banana plugs for the amp.

 

Removed the grill cloth and the pad cloth.

 

1cm foam raiser for the pads.

 

Some sound deadener around the inside of the cups (under the grille for vibration reduction). Planars don't vibrate much anyways, but I thought while I was at it.

What i understand:

Cloth removal for opening the sound.

Foam raiser to get more distance between ears and drivers.

 

Questions:

Why did you remove the 2.5mm connectors? Wouldn´t it be easier to just make 2,5mm to banana plugs cables?

Or will the sound benefit from removing the connectors because you have one "contact area" less?

If you connect the new cable with spades to the cables coming from the drivers you kind of add another "contact" that you removed with the 2.5mm, or am i missing something?

And if the new cables are directly connected to the drivers, how do you manage to get sufficient strain relief?

 

Just want to know out of interest, no intention on arguing over the actuel benefits one gets from those mods :-)

Oh and if you have pictures that would be nice too :-)

They were crackling after one month,  they become loose. They are not a good way to connect to headphones, I have always had drop outs with amps and jack connectors, sick of them. The sound improved in leaps and bounds when I connected directly to the drivers. Partially because it was direct and I also suspect an increase in wire size also helped a lot.

Type of contact, stereo jacks ar really crappy.

Spades are better, no drop outs, you can use bigger wire.

 

And if the new cables are directly connected to the drivers, how do you manage to get sufficient strain relief?

 

Good question, did not mention that i wrapped the wire around the inside of the cup from the opposite side first, right around, taking the strain off of the spades.. Holding it all in place with sound deadener, like dynamat with foam. Sticky like blutak on one side and foam on the other.

Lost my camera a while back, just got the crappy phone, sorry.

Thanks for the extensive answers, really appretiate it :-)

 

One more thing, you said you connected the new cables via spades, but not in detail.

Did you solder the spades to one end of the new cables and then crimped those to the wires coming from the drivers?

That's if you plan on staying portable. Otherwise, I'd suggest a desktop amp/dac with a warm tone to use off your computer. I personally have the Audio-GD NFB-15 on my desk.


Nonsence. I have a DX80 and iDSD micro, after volume matching HE400i sound equally great on both.

Anyone have both the 400i and Edition X, or have tried both? I'd like to know how much improvement there is in sound quality comparing the two, and if the Edition X is worth more than 3x the price.

Edition X has a much softer sound with a substantially improved soundstage. HE400i has a much more aggressive sound. I preferred the HE400i even putting price aside, but it totally depends on your preferences.

Simple answer: NO  They have different sound signatures so its not like you are comparing apples to apples.  As the poster above noted the HE-X has a more relaxed sound while the HE-400i has more of an edge to it.  It will also depend on the type of music that you like that will pair well with either headphone.

Yes, soldered the spades on the driver wires and the cable wires.

Agreed with both @fjrabon and @DavidA as they posted above.

I'm in total agreement with fjrabon on the HEX vs. 400i. I take it a step further though, in that I personally disliked the HEX. The presentation was so soft, so lifeless, that it took all of the enjoyment out of music. The soundstage was good, but nothing spectacular, which was apparent as soon as I heard my HD 800 S's. I got to compare the HEX to the 800S, and they couldn't be more different in presentation.

Going back to the 400i's is easy, at any rate. I greatly preferred them to the HEX in every way except the ability to run out of my iPhone. But that's about it.

I can't comment on either of those devices. I was only making suggestions because the op felt his 400i sounded "distant." I had a similar situation off my portable device (Sony A17), and adding a Cayin C5 helped quite noticeably. The C5 (and E12), however, are quite beefy compared to most portable amps.
