I have some fairly vintage Hi-Fi and keep wondering whether the time has come to upgrade to something that will (hopefully) sound even better. The trouble is that my current setup sounds good to me and I worry that new gear may not actually be a significant improvement. Unfortunately I've never had chance to listen to any hi-fi other than my own so I really have no idea what might be possible in terms of improved sound. My current setup is a Technics SL-PG400A CD player (approx 1990), a Pioneer SA-508 amplifier (1980) and Celestion Ditton 15XR speakers (1980). I also have a Rega Planar 2 turntable. I've spent a fair bit on new cables, stands etc to provide the best possible conditions for my elderly equipment and all the gear has been regularly used and well cared for. Does anyone have any thoughts on all this? If I do go for new gear I'm currently thinking in terms of a Rega Saturn CD player / Rega Elex Mk4 amp or possibly Naim CD5si / Naim Nait 5si amp. I've no idea about speakers at the moment.
