Yape, I am getting speakers soon. I prefer speakers than headphones in summer :)

It's awesome having both a great speaker rig and a headphone rig. Even better when they are one and the same.

Yes, you're asking for too much. :p FWIW, I had and sold the HE-6...the LCD-2/3/X/XC were all preferred by my ears (and more comfortable too). :o 

Wow, how long did you have the HE 6 for? My friend is loaning me one and as you know I have the 3 and the XC. If the fit is anything like the 500, that's bad.

I had them for over a year...threw many headphone and speaker amps at them and don't really miss them much. The fit is ideal to the HE-500s.

Thanks. Reverting to the 900, I find that my ZD tube amp helps the mids out quite a bit. Not complaining too much any more about recessed.

others have commented that the ZDSE is a bit too tubey for the already euphonic TH900. How have you found it? Have you had to do much tube rolling or tweaking to get a sound you are happy with?

I bought the ZD from a head-fi'er recently and have done no rolling at all. He changed some tubes. I am very happy with the sound and the consistent thing is the bringing forward of the midrange. It is a just a tad too forward with the XC but I do not find it a problem at all.

that's not the impression i get of the zdse based on what i've read. folks describe it as sounding closer to ss than tubey. don't hear the th900 as euphoric either. if anything it leans towards a drier sound to my ears. pairing it with a tube amp might add some lushness.

Have you paired it with a tube amp ? If so, which ones ?

Like I said, I don't hear the "tubey" sound at all. The ZD is very very good in that aspect. But to my ears there is some lushness when I play the TH900 off the ZD compared to say the Mojo.

yep - a woo wa6 and a carey integrated tube amp. can't remember the model but it had quite a few tubes. the th900 sounded gorgeous out of that rig.

yeah that seems to be the general description of the zd - a hint of lushness but not at all tubey in an overly warm, syrupy way

... and must be really comfortable..

 

Except the HD800 sound stage (though you can get close), you can mostly get these if you are willing to experiment a bit. Buy the TH900 and change the foam dampers around the drivers to 100% wool felt rings (with no acrylic content). Quality, density and thickness matter a lot (take your time to experiment with 3,4,5,6 mm thick felt rings with different densities). This will make the midrange much more alive. The trick is to find the least density/thickness for which the bass does not become over-damped. 

 

If you want better sound stage and deeper bass, follow my ear pad mod described earlier in this forum. In the same time, halve the amount of filling in the cups (the original filling works well, but I needed less of it). No, it won't overhang the bass, since the felt rings will keep it in control.

 

I don't know how the Lawton mod sounds; from the feedback on this forum it seems to improve the bass control, but the above mods made my TH900 a different headphone primarily in what the midrange tone and immediacy is concerned, and the bass is glorious. Absolutely no hollowness any more. Far more of a change than any source or amplifier could cause.

 

Even if you are not doing these mods, for me the TH900 is currently the best compromise in closed headphones, even in stock form.

The drivers are likely the best dynamic drivers currently, especially when this type of loading is used (reminds to a short transmission line, which is also why the dampers are so critical).

 

It is also possible that the Audeze XC would respond well to mods, but I never tried, since it's just too expensive for trying, too heavy for the neck and the sound stage is too narrow to begin with. From what I've learned from tuning headphones, it seems that the ear pad is too high, with the opening too small. Also, the Audeze pad is too much angled IMO. Likely it should be personalized, depending on the listener's ear structure. I can imagine that most of the deficiencies are related to the ear pad design. I would need to listen to the bare drivers to tell.

 

[ Based on design, I think the best stock pad is the Stax EP-009 (for the SR-009), but it's 140 euros and one can do even better. I can most definitely hear the effect of the filling material, and it makes a huge difference. Depending on headphone, the optimal filling is different. The TH900 so far works best with a ring cut from active carbon foam sheet for filling (very loose structure). My Stax 007 Mk1 ended up working best with a filling made of a layer of felt ring and a layer of foam ring (thickness matters to the 0.5 mm precision). In theory, pure felt rings would be the best, since they offer the most uniform damping over the widest frequency range (other than the quite impractical goose down), but one should optimize the density for each headphone, which is hard to achieve unless ones makes own felt. It was much easier to combine a commercially available felt ring with a foam ring. Probably not optimal yet, but I am in awe how much better the sound became on the 007 Mk1, it's a more dramatic difference than on the TH900. The sound stage is wider and slightly less high than the HD800 stage, but much more precise with similar or better depth. The sound surrounds me in a huge bubble which extends well to front and back. And this is with a pad which is only _very_ slightly angled, and steeper angle is worse. The modded TH900 sound stage is almost as wide as the HD800, but less high than the HD800 or SR-007. Depth is less, but it doesn't sound inside my head. ]

Thanks for the great info, I don't think I will modify headphone anymore after I busted my beyerdynamic T70 voice coil while experimenting the sound signature change.

That voice coil is very very thin to work with ! :(

 

I might try diff pads but that's as far as I will go, bit scary now.

 

And I am done with Audeze, not really into dark sounding headphones with lot of discomfort and weight.

 

Thanks again !

This actually looks really interesting! The Subpac seems a little bit cumbersome and clunky though. Also, I'm not usually sitting when I'm listening to music. I like to dance around. The "Woojer" might be something I'd try.

 

(When they actually get them to market, that is!)
