Mdr-z7 vs. Alpha Dogs
mac mini-> audirvana+ -> exogal comet -> lehmann linear -> cans
The lehmann is mine but everything else belongs to the shop (Munkong Gadget, Bangkok). The Exogal actually has a headphone out, but i'm not familiar with it and not entirely sure how good its headphone out is, so i decided to stick with the lehmann which i find to be quite neutral and more than capable of driving my ad (with 10dB gain setting).
I forgot to bring my mbp so Norah Jones on dsd64 was first up. Immediately noticeable was the much wider soundstage on the z7. The difference is quite staggering. The gain in width is at a slight sacrifice of the depth of the soundstage compared to the ad, at lest it seems to these ears. What i have problems with is what seems to be the slightly prolonged decay of the bass notes. It sounds almost resonant at times which is odd. I adjusted the fit (which is crazy comfortable, btw) but this oddity remains.
The mids and treble to these amateurish ears are good. Less intimate than the ad's but very smooth and there was no piercing sibilance or peaks that i could detect. (I also feel the exogal is extremely 'analog' sounding which might have helped) In fact, i rather like its very relaxed qualities a little more than the alpha dogs which seems to have this hd800-ish treble at times.
Moving on to "Dark Knight Rises" the soundtrack - the difference between the two was really apparent. The track "a storm is coming" was just not happening on the ad's. Here the z7 clearly went *much* lower. What was fluttering on the ad's became proper rumbles with the z7. In "A Fire Rises" from about 2:40 onwards, the z7's bass vs. the ad's lack thereof was very clear. Now while there ARE these added lower frequencies, it's also very clear that it's very umm... wobbly/wooly it's almost as if the driver, baffle and cup assemblies were vibrating(?).
The Z7's are like listening to big speakers, with lots of space in between while the ad's are like a really good pair of monitors, toed in at your head, fairly close by. I like both and i can see more people enjoying the z7 more. They really do do a lot of things well. What spoils it for the z7 for me is while it sounds as if it has an added subwoofer (compared to the ad's), sadly it is also a pretty badly set up subwoofer.
Which is a shame. Sony has so much right here and the build quality and comfort are both excellent. The presence of its bass is probably what gives it a really nice sense of space and it is a very pleasant effect for a nearly closed pair of cans at this price. But the weird bass is just too big a spoiler for me. May be a mkII version will have this fixed? Perhaps someone can come up with a mod for them? That'd make a pretty awesome pair of cans. But in its stock form, i don't think they're for me... At least now for now...
