Old expensive Stack System Vs New Amp+Speakers

[smogsy]

I Love my music & so i bought myself a NAD BEE 315 & Morduant Short 902i. its sounds very clear and good.

However my mum also has a Very old Stack System 14+ years old. she apparently paid £1000 for this stack system. (picture found on google)
now every time i hear the stack system it just WoW me. i Don't know the model of the system i will find out later, as dad is painting the room it is in.
Question is, Which should sound better?
is it just me thinking it sounds better?

hope you can help!
