I saw this nifty old CD player (NEC Multipsin 6x) which I've done some research on it and it seems like a really cheap introduction into a audiophile grade setup. And before you say I don't need this as a source, I realize this, but I don't want to be tethered to my 3x3x1.5 foot computer to listen to my music. I'd like to move around with it a bit. Obviously I'm still sitting next to a power outlet, but I can at least carry this thing around and it is much lighter than my computer.
Here is the page that peaked my interest.: http://www.positive-feedback.com/Issue3/cdrom.htm
Mr. Morawski laid it out and definitely interest me, although I definitely will not be buying that muse 2 (definitely not a introduction level piece of equipment.)
So after the brief introductory, I just want to ask you guys (with your vast knowledge) what you think would be a fitting DAC/Amp for my purposes. I'll list a checklist of things I think would be beneficial for my use, but do not take that as "the only way" in my eyes, just what I think as of right now. Please correct me as necessary.
1) I'd like it not to exceed the width and length of the cd player, which is pretty big. Should be around (5.5x9 inches or so.) I don't expect it to be that hard to do. Most of the more portable dac/amps are a small form factor as of right now.
2) When I say say semi portable I mean still be battery powered but still give me noticeable increase in sound quality (at least for the money)
3) Speaking of money, I'd like to keep it under 100 dollars, I'm definitely a newcomer so I need to start off small, monetarily.
4) This last one is from some research I've done. I've read I should be using s/pdif over coaxial cable whenever possible for converting and amping, plus this cd player only has coax (1990s tech).
I'm sure something out there exists, I'm going be surfing this forum and researching the web until I find something. But if any of you nice people would like to help me along the way or just enlighten me on my most assured misinformation, please do so. :)
