Hi I have an ageing seperates system that I built up from the late 80s to the earlier 90s.It consists of a rega/p2,creek 4040s2,marantz 50se cd player,nakamichi tape deck,rogers ls6a2 speakers biwired.I am thinking of upgrading the amp and cd player and wondered what sort of money I would have to spend to improve the sound.As things have come a long way since these were purchased i wondered if some of the stuff that places like richer sounds would be good.I can't afford to spend to much as kids and a mortgage have arrived since I was out buying this stuff.Any help would be appreciated thanks.
