I just don’t have the money for a multiple source system Clive so it’s not a problem I’ll be dealing with. 
I do have time; full time employment for good or bad is past for me, I don’t need that sort of money any more anyway. 
I have most of what I need, kids are grown up, ex wife has the house (for now
) don’t do telly, cars, drink, smoke, TV, gadgets and poodle along doing pretty much as I please which is pretty much file audio, sax parping, dancing and friends and family.
I’m pleased you appreciate my passion John and yes, its amazing that for a relatively small outlay a well set up file based system can rival some seriously expensive record players.
