Gotta agree with tdock. The Q701 is best in a quiet environment. I was listening in my laboratory, modding the mod (more on that in a bit), and the two PCs were quite noticeable. I even heard my wife in the kitchen below me, through open windows, when there was a quiet section in the music. I also heard the Q701 while she was listening to Hugh Laurie in another room. She tends to have things louder than most, I'd say, but still it was quite audible. That was when I had them "properly" modded.
tdock,
to answer a couple earlier questions you asked, yes, I'm the guy with the Mogami cable on them. I don't use the stock, and won't unless I need a 1/4" plug, but because you asked, I did a comparison between the short stock and the Mogami. At first I thought the stock delivered more low end. Then I realized the Mogami is more detailed, so the bass/low end may seem a little lacking. That's definitely not the case (OK, I've no quantitative data to back that up
). I also think that the added detail and clarity of the Mogami may make the sound stage seem just a bit bigger or more airy. I'm very pleased I had that cable made, but it may not be for everyone. It was pretty good with the mod, but...

Try some type of foam. You might like the sound.
...I just didn't like the bass with the mod. For some things it was great, but when I found songs that have some serious low end, the emphasis was too much. So, back to the lab. First I went back to blue painter's tape, as it proved plenty sticky to hold. But the impact of the low end all but disappeared. So I pulled it, tested the mod again, then tried two different types of foam.
The first foam I tried is very soft and pliable. It can be rolled into a tube... haha!... so, not stiff at all. It came with a case I got from eBay (read: China), along with that far less porous, stiffer whitish foam packing stuff. Quite a nice case for storage, though maybe not as stiff as a Hippo (too rich for my blood). But I digress. This black foam was just about the right thickness to slide under the black plastic piece and screw that sit just above the bass port. It was easy to cut into any shape, but a rough square was about right. As for the sound, while there was more bass/low end, the overall sound was a bit muddied. Some people might even prefer that, as it wasn't terrible, but it wasn't what I wanted.
One nice thing about the foam mod, it's really easy to do and undo. I had a piece of thick aluminum or thin sheet metal from which I cut a strip, then bent one end into a curving 90 degree angle (hope that makes sense). With that I could carefully get the foam under that plastic piece, and thus cover the port. The other end was good at pulling it back until I got the foam where I wanted it. DIY tools FTW
The other type of foam I have came from the box for my Grado SR225. It's nice and stiff, and the porosity is different than the other. The trick was to cut it evenly and with the appropriate thickness. That was definitely the most time consuming step. In the end I used a fresh razor blade for a box cutter. That was the only thing that would cut through it with any sense of controlling the cut. My desk is littered with foam scraps. The sound regained its clarity and detail, and the bass is controlled the way I want it. While there's more than with tape over the port, it's decidedly less than the open port. So clearly it won't be for everyone, esp. if you're happy with "the mod."
I'm not sure it's worth it for those who tried the mod but reversed it. That depends on how much you like taking apart and reassembling your Q701. One note of caution on that: I've now got a stuck screw. While I could probably force it out, I'm not inclined to, as I'm very happy with this modded mod. Guess I unscrewed that one once too often. If the sound were really bad, I'd force it out, for sure. Just something for which you should be prepared if you mod a lot.
Cheers
