Tascam DP-01 FX/CD

Hey peoples, I was wondering if I might just share a serious gear-related concern I have, and some related questions. Thanks in advance for any helpful input.

I just can't get a loud, crisp sound from anything I record into my Tascam DP-01 FX/CD. Its resolution is only 16-bits, could this be the reason why? Can it really be this bad? After uploading onto my computer hard drive, I compare my mixes to anything on blogs or youtube, and they consistently sound crisper, that is to say, more resolute, deeper and brighter.

Will a 24-bit DAW afford my recordings a similar aural sheen? I'm looking at Cubase and Abelton Live. Will these programs help me to produce a louder, crisper sound?

I'm aware of equipment, such as condensor mics, mic preamps and the like, but this is strictly a question about recorders. Any positive input much appreciated. Thank you.

C'mon, no comments, advice, etc.?

I use my Dp01 alot and I also use various DAWS and firewire interfaces.I've never noticed any clarity issues.I will say that maybe your expecting too much from a $300 recorder.When I went a real "shiny suit man" sound I opt for the DAW and plugins.Something else I do is track my beats and scrathes into the DP01 and then transfer the files thru USB to my computer DAW.I find the DP01 easy for punching in and out for scratches and I use it to flesh out rough ideas.
