the age dont really matter it's how the gear was built to begin with,i actually prefer vintage speakers over most newer model's,i think speaker builder's/designer's have lost their way in the last 20 year's or so.
Can a vintage piece over 40 years old be Highend
I have a passion for listening to modern sound reproduction both tube and SS with matching gear, but also sentmental vintage equipment. I have speakers that were considered very much Hi-Fi in there day and an old working amp to go with it which was also Hi-Fi can they be called High-End?? The yougest of these is about 42 years old the oldest 46. ( I am discounting altogether the pieces from the 70s which I own and listen to from time to time also)
