can this amplifier give an equal quality like VS4121 altec lansing spaker?

Such a project (amp powered from USB) may be possible if the speakers are very high efficiency (USB cannot deliver much power). For sure not a beginner's project, sorry.

If USB is not strictly necessary, you have many choices

Have fun, Hannes

Perhaps you are in the wrong forum for usb expertise.

Sorry, but it's a bit absurd - USB gives you 5V and 500 mA - that's hardly enough for decent headamp...

If you want a good answer to your question you have to be more specific:
- what will it be used for?
- what power do you need?
- what is you budget for this project?
- what kind of amp you want, class A, AB, gainclone, tube, solid state...?
The more details you give, the better answer you'll get

Judging from your speaker's description I think gainclones will fit the bill and that's in another section of this forum...
