All you need to do is check the specs such as the input/output impedances, output voltage, input sensitivity, of the connecting components and make sure they are good matches. Age really makes no difference.
Old Ampfiliers with new Processors
I confess my reason for the question is to save money. New Ampfiliers are very expensive. Procsssors change with the times and updates. I'm interested ventage amps Carver , levinson and any other good Amp you could suggest. Whats the difference between a new amp 200 wpc and a ventage amp at 200 wpc. Ventage amps are so much lighter in weight compared to new amps weighing 60 to 100 pounds. The ventage amp is to accompany a new processor.
