I'm glad I decided to give the Z6 a chance. I think it's more comfortable (from memory of the Z7) and definitely the pleather pads give the lower-end a nice boost.
Since they share the same driver specs, in hindsight I should have tried out some pleather pads on the Z7 - might have given similar results... but could also be a lot worse :P
Anyone try pad rolling on the Z7?
drivers are different, Z7 has a thicker palladium coating and is tuned looser to compensate for the fabric pads
theres also a leather-padded version of the Z7 that's EU-only; I've never seen a pair but the Z7 is pictured with pleather pads in the manual. I did put the Z6 pleather pads on my Z7 when I owned both and it sounded muddy and slow, until I adjusted the damping to the driver, after which it sounded <MUCH> better than any of the other Z headphones did in stock form (!!!)
Z6 is good, very clean and tight sounding, but very very "in-your-face" and closed-in sounding, only made worse by the serious lack of content above 2kHz -- this is caused by the pads and can be mitigated with the right pad swap at the cost of all that lovely bass extension. the pads also restrict airflow and affect the driver's transient speed. there may be more potential to be gained from them but I never managed to get a good sounding pad configuration before one of the channels on my pair died (on the THIRD pair I've owned for the THIRD time) so #fack
here's a quick FR plot of the (stock) Z6 before I go to bed -- very very flat, smooth and extended from bass to midrange with an extremely gentle "V" shaped sound signature. nice sounding headphones but absolutely not worth anywhere near the going prices (same goes for the Z7) due to the severe lack of any and all treble, poor comfort, and poor ear canal resonance behavior (which makes that little bump from 2-3kHz notably more violent than it looks on my rig). maybe viable as a transportable due to isolation and being easy to power? nope, because they're extremely fragile, not durable at all, especially the cable and drivers -- be VERY careful buying these online as they break very easily. disassembling the headband can crack the sliders and cause them to break, the cable is extremely fragile and tends to develop shorting under normal use, and the pads become hard, stiff, and deflated very easily, which will cause 2-3kHz to become emphasized more severely and kill off low bass extension. Even after receiving them I'd exercise extreme care by keeping them on some form of stand or in the storage box, moving the cable as little as possible, and wiping off the earpads thoroughly after each use with a microfiber cloth.
I'd value these at maybe $250-300, if complete and in great shape. Z7 might be more around $400, again only if in great shape.
BTW: driver matching on these is ABSOLUTELY ******* RIDICULOUS for the age. These were produced VERY carefully by Sony, and likely matched and tuned by hand.
EDIT: here's a quick comparo graph against my modded Sansui SS-100 (my current reference):
