for sound cards, hd 580, no pity... I use a hd 580 on my diamond s70 sound card, which have a not-too-bad on-card headamp. it sound good... if you can make a amp at a low price, go get hd 580...

I have a HD580. Now, I use it with my Diamond S70. It is not too bad. I think it can get more than 50% of its potential¡* For portable use, I don¡¯t think it is possible without an Amp. (I don¡¯t know much about the old Sony Discman)¡* For CD Player Headphone out, It is hard to say. Depend...

Yes, you are right. I need a good CD Player. I am thinking of Musical Fidelity X-RAY CD Player... My Sony D321 is from a good friend. I will use it temporarily...

It is a product of 1992. how is it?... Does it enough for my Senn HD580? (I have a headphone Amp)...

haha, I will buy a new HD590 tomorrow. As a beginner, I guess I will be a defender of what I have. I will use it for my diamond S70 sound card. But a good CD player is in my mind... I think a NEWAGE is coming, as more and more people ditch the old classical products and enbrace the new ones...

solomon, have you ever use yeli TA28, which is at the same price with G&W T2A? how is that? which one you recommend me to buy?
