Yesterday my Q701 sounded the best it's ever sounded. It seems like there's some bass that's come out of nowhere and it's just weird. I was listening to some "On Stranger Tides" songs and it's as if the bass on the Q701 was almost up to the DJ100 level.
I removed my pads and noticed two hairs in there and then that the foam pieces were both different. One was really coarse, rougher and more sparkly. The other was the K701 type that was very soft and not sparkly. I put two similar pieces in.
I really does seem that putting in identical pieces somehow does seem to effect the sound a tiny bit. Could also be placebo or that some burn in has occurred before doing all this. Right now I have probably 250+ hours on them. If I think the foam won't effect the sound in some ultra tiny way, it doesn't mean it doesn't. I think you'd have to have golden years to tell the differences. It did feel like the soundstage was a tiny bit bigger and the sound a little more clear, but this has got to be placebo. Maybe the wrong foam types could be why the soundstage on my pair seemed smaller? Virtually impossible right? Who knows.
Maybe people who own the Q701 can make sure to check their foam. They should both look the same and not any different.
BTW you can definitely hear the difference between the foam installed and then removed. Not anything major and definitely a tiny loss of bass. I know this is hard to believe! It makes sense though.
Also..I tried these last night with an Ipod Touch 2G with LOD to a Total Airhead. This thing drives them with ease! No blinking red light (over voltage) even once. The soundstage is the smallest it's ever been, but not bad for a portable amp! Seems to have perfect synergy with the Q701. Seems very clear and detailed with no loss of bass at all.
I actually heard something in one of my songs I've heard thousands of times for the first time using the Airhead. Sounded like a man whispering in the background before a song starts. I'll have to listen for it on my KRKs and other amps. Could just be due to the more forward mids and smaller soundstage. This rarely happens for me believe it or not. I need to review this amp. It's one of my favorites and can drive almost anything quite well. One of the few portable amps that still uses AAA batteries.
