Ah right! Well we all hear differently but I think the mod has "saved" the Q701s for me. I loved everything else, great bargain, but the lightness of bass bothered me too much eventually. That's what forced me into trying the mod and I'm glad I did.
I think people who've gone out of their way to find DACs and amps that are particularly warm, to "fix" the Q701, might have a different take. I don't have that issue.
I'm with you 100%. While I'd probably still own them without the mod, they wouldn't get nearly as much head time. For me, replacing the foam rings around the driver with wool felt really helped tame some occasional harshness, giving the Qs even more head time. Since those rings are easily switched, and I've got five or so pairs now, it's easy to tweak the sound. Such changes might not be for everyone, of course, but talk about cheap and easy. Takes less than 60 seconds to switch those rings.
Driving them with a Lyr mostly, I find that tubes make a significant difference. I went from a pair of 1974 Voskhod Rockets to a pair of RTC E188CCs this morning, and the drop in bass quantity was undeniable. But also the air and gorgeous top end came back. The muscular Russian tubes are fun, and great at the price, but there's a sense of refinement with the E188CCs. Of course, I really put 'em in for my HE-500s I've got better (and less expensive) tubes for the Qs.
Yes, sorry about that. Wasn't phrased so clearly. I am indeed saying that the Qs look cool (I have white, so they've been nicknamed my stormtrooper headphones - and stormtroopers are cool, OK?!) and sound great. However, if you mod them, they no longer sound great, but they do still look cool. The sound separation is one of the major pluses for the Qs. Most people here have said that that quality gets lost after doing the mod (and I agree, it's basically gone), so I would question the benefit of modding the Qs. For a very nice sounding headphone with more bass, I'd recommend something like the Beyerdynamic DT990. They don't look like Princess Leia's Stormtrooper offspring, but they're not ugly.
Yeah, the Stormtrooper model rules Of course, Vader would not approve of the musical-notes bandana I've got wrapped around the headband. He'd want us all to suffer those #$%!@^# bumps.
Obviously we differ re: what we want from the Qs, but that's cool. I chose to mod them (aware I could reverse everything but the headband mod) rather than sell them and try another and another and another. For my money and efforts, I'm happy to keep them.
