I have a cop computer but I'm not a cop. A friend of mine asked me if I was when I told him the make and model of my computer. A used computer salesman told me it was a great computer so I bought it. I have the CF-F8.
Ok, it's a 2008 computer. It was pretty decent, but now it's nothing to write home about. Curious of two things: a) do you care for it's tough physical specs or not and b) how much did you paid for it and when?
One day I might figure out how to put music files on my phone. I don't really like how my phone sounds through the speakers though I could try talking to someone with headphones on to see if it seems better.
Yes, phone audio will sound very good with headphones (unlike it's tiny built-in speaker) Look for headphones with low impedance (50 or less, preferably closer to 30 and high efficiency/sensitivity
Before you invest any money into DAC, get decent headphones first. As for getting music on your phone, it's shouldn't be hard. With Iphone you could use windows version of itunes (free) or with android - simply plug the device to your laptop, select file sharing over usb on the phone and simply drag and drop files into music folder
