Mine sound thin and sibilant directly out of my player (Pioneer XDP-30R) so I know what you mean there. It should have enough power to drive them just fine but it just doesn't do it for me. Out of my tube amp though they come to life. They don't have the speed of my other cans so it can get a...

I think you'll be satisfied. I got a set a couple weeks ago and now that they've racked up some hours I think they're great for the price. Quite a neutral sound with good range and detail, and at least for me they're comfortable to wear for hours. I had never heard of the things but after...

Precisely. The Portapros sound a bit different depending on the temple pad setting as well.

4AAs could probably be used as weapons. Be sure to give them plenty of burn-in and as much power as you can provide. Still great headphones despite being over 40 years old.

For the 4AAs, the new drivers were earwrenchingly harsh and tinny. Over time they mellowed out and now they're some of my most transparent headphones. The highs can still be a little grating sometimes but there's a lot of detail and clarity in the sound.   The 4AAAs in their current state...

I also recently got my 4AAAs rebuilt. The sound is much different before burn-in but they're improving little by little as the hour start to rack up. My AAs weren't very nice to listen to until I got them over probably 80 hours.

There are some kinds of shoelaces that are (or can be made to be) hollow on the inside. If you found some of those you could probably use them to sheath the cable.

I'm actually down in Oak Creek.

K141s sound awesome amped. Prepare yourself.

They're more of a flat black in person. Also, if you get them expect them to sound like garbage until they get a hundred hours or so on them. They'll probably need a decent amp too if their forefathers are any indication.

Nope. So far I've brought them 4AA, SB49 (twice), and UR40s. Haven't had to jump through any hoops, do any registration, have any receipts, or anything. They pretty much take them and replace them if they're lower-end models or rebuild them if they're higher-end. I think the only thing they...

I'll be stopping by some time in the next few weeks and I'll ask them why they're so uncommon. The last time i was there (late summer) they didn't have either model in the outlet store to try.

I'm a bit south in Oak Creek and attend school in Whitewater, but I find it's always worth it to make the trip every once in a while and just chat about headphones with the receptionist.

You beat me to it. Just listened to December last night trying to fall asleep.   Quote:

I've let mine run overnight a few times without problems.
