I am not much of a reviewer so I can't give details on say the bass was so much better etc. I just listen to the music and I am pretty easy to please unless something is obviously really crappy.

Having said that I do think the portable desktop is just a little bit better somewhere in the music chain then my 06 micro stack which I no longer own.
So I am going on memory. The sound seems more full and I am certain there is more detail.

I upgraded to the desktop mostly for convenience and because I still wanted a battery operated unit. I like all the convenience features it has such has both a 1/4 inch and 1/8 inch heaphone inputs.

I don't kid myself that it is as good as the Ultra Micros or anything. But it sounds very nice to me.

Currently my main use is using it either with usb and my notebook at work. But I also dusted off my Sony JE530 Minidisc deck which I just keep at the office and am using the optical output from it into the amp. The former combination sounds just wonderful even with compressed atrac music.
