http://www.echoaudio.com/Products/Ca...goIO/specs.php this the one? It only has analog out though. I'm after a digital out (coax / toslink). toslink is preferable (my current notebook has ground loop problems).

I'm thinking of moving my entire cd collection onto harddisk (flac / or other lossless format) and playing from a notebook. I mostly listen to music via a hifi system (only headphone occasionally these days). is there a usb device out there which does digital out (so I can link it to an...

i get these noises from my laptop and pc as well. Are you by any chance using Windows 2000? I've noticed I only get these noises when using 2000. The noises went away when I changed to xp or nt.

Does anyone have any tips on how to solder a cct using those boards without premade tracks. Soldering free wires to connect between components looks pretty hard. Up to now, i've only been using pretracked boards and have gotten away with jumpering to connect tracks. I've seen the pics...

Can anyone point me to some good recordings of Louis Armstrong or Duke Ellington?

I'm thinking of upgrading my JVC integrated amp for something better. Currently looking at either the Denon PMA-255UK or the NAD C320. I'm looking to spend AUD $500 - $700. Does anyone know how these two compare? Any other recommended amps (around the same price)? Thanks!

meatman. Please post some comments after you've had the chance to make a comparison. Would be much appreciated!

I'm new to this What's the difference between headphone specific amps and the standard hifi amps I'm using to drive my speakers? I've currently got an JVC integrated amp and Pioneer CD player with floor speakers (nothing speccy, just what I could afford while I was at Uni 8 years ago)...

Theoretically the opposing sound wave 'cancels' out the noise wave. It's not tricking the brain. The sound wave actually disappears! However, I've got no idea what happens in practice.

do they really work? or are they a great gimmick? How well do they work on planes? Have anyone tried these? How do they compare to say using a closed pair of phones?
