Quality required to hear vinyl

I'm interested in putting together a system that is good enough tell the difference between a CD and vinyl. I want to hear why people still buy and listen to vinyl.

Currently I'm looking at:

musical fidelity a5
Epos M16i Floorstanding Speakers
and a Rega P3 or P5

Is this going to send me into vinyl bliss, or should I quit till I have much more cash...

Thanks,
Bill
