Hi, I'm a relatively new member. I have been lurking for a while and have gotten addicted to AK and its many forums. I have an Onkyo A-5 that I have owned, I think, since '77 or '78, It sounds great today, as good as it did originally. I have gotten bit by the vintage bug reciently and have aquired an A-10 that sounds terrific, also #2 T-9 tuners and a T-4 and they all sound fantastic. When I compare them to Yamaha state of the art Home Theater systems that I own, these old units have nothing to envy the newer units as far as sound quality is concerned.
