I’ve already built myself a shorter cable and have a pair of Beyerdynamic pleather pads coming my way. I love Beyer’s pads and the Q40's, though comfortable, are a bit thin and the pleather on them is pretty thin as well and I don’t think will stand the test of time. Of course that is purely conjecture on my part but, again, I’m a big fan of Beyer’s earpads so I probably would’ve replaced them regardless.
I plan on doing an A/B comparison with my Denon D1000s. I wish I still had my RP-21s since that would’ve been a real apples to apples comparison in regards to both being designed as studio monitors and both have similar price points. I’ll also directly compare them to my DT990/600s since the 990s are fairly well known on Head-Fi and will give others some point of reference.
I’m not saying the Q40s are giant killers but for the $130-$140 price point, they are very very good in my book.
How did you build your own cable when the jack in the headphones is threaded? All the plugs I can find are too big to fit inside the threads, and there don't seem to be any threaded plugs available.
