So, pre modded and post modded, what is the Chang approved price?

Still trying to sort my thoughts out. I'm without my main DAC for a while, so everything, including the HD800, doesn't quite sound up to snuff. I will say that the effect of mods is significant (-4db drop across the bass should be after all, and as you can see, there is nothing inside those cups to prevent that hollow or cupped hands coloration).

With mods, the Z7 is solid upper mid-fi vying for the next level. What prevents the jump to "Summit-Fi" is lack of ultimate clarity and transient response. The FR with the mods is top-notch - not totally neutral, but a warm relaxed sound. There's the argument that with mods, this may better than TH900 because we already know more than a few people go eventually got sick of that TH900's treble spike and sold theirs.

I can see myself using this at work because it looks like a normal headphone and doesn't look retarded from a layman's POV. As munch said above, the Z7 will be more compelling once the price goes down.

Based on impressions here so far, seems like a $300-$400 value proposition once modded?  I get the feeling that the TH900 still has better clarity than the Z7?  Would be a shame since the SA5000 has excellent overall clarity.

Half the retail value? I think that might be a record. TH900 has more bass, more wubwub going on. Couldn't stand it.

Putting this on the loaner program:
