I want to get the Iaudio U2 1GB flash player. Sadly, it does not come with a bundled AC adapter to charge the player directly from a wall outlet. I happen to have one of those Ipod USB adapter chargers. Theoretically, I can take the USB cable (with the U2 plugged into the other end) and plug it...

When music is playing to my amp, should I turn it on with the volume at my desired music level or should I have at the lowest and turn it up? Or does it not matter? I am afraid that by turning it on with music playing at a loud level that it will damage the amp/headphones.

Holy cow, is this cheap or what? This is almost a steal! The Karma is even cheaper than the Zen Touch which goes for $250. I was thinking about getting the Touch. Should I go for the Karma instead? Zen Touch Does Not Have: -Dock -Visual Eye Candy Meters and Analysers -Bitrate Display...

Does anyone know if Iriver will be releasing the H10 model with a larger hard drive? Maybe 20 gigs?

I am running my Beyerdynamic DT440s straight from my Chaintech AV710. My question is: will these cans benefit substantially from a headphone amp? And if it will, with which amp specifically? Please include the cost. Thanks!

I just got my DT440s and I am pretty satisfied with the sound, except the Lows could be better. What is really getting to me is the top part of the headband, which presses on the top my head really hard and it begins to hurt after some time. I gave my head 1 week of getting used to these new...

I am thinking about getting the Sennheiser 570s to replace my cheap Jensen headphones. I especially like the detachable wire on one side of the headphone and the material of the bowls. Are these good headphones for Trance music listening? I don't know how Sennheisers do with trance. I am looking...

I have read a lot of posts here at head-fi and you guys turned me into an aspiring audiophile! Although I am convinced by the opinions here about headphones, I would still like to try out the headphones for myself. True, the devices set up for demos are probably poor (unamped, etc) and the...

What do you guys think is the best sound stage headphone (no ear plugs) that does not require an amp? I want to get such a headphone for my SBLive1 soundcard, primarily to listen to trance music.

I have a control for my Iriver IMP350 cdplayer and I unplug it every time I don't use it to prevent my SONY MDREX71 cable from getting tangled. I plug them in when I use it and it feels like I am wearing down the parts. Does doing this harm any components or affect anything? Should I leave it...
