Reason I write ..... my brother recently aquired a Pioneer SA 8800 Amp, Luxman deck with Ortofon moving coil cartridge & Celestion Ditton speakers.
To be blunt, I have a reasonable vintage collection of B&O systems including Penta's and his "silver gear" blows me away - against my set up's, his sounds far superior.
So, did the silver amp era dominate????
Probably not that much when this equipment was new. B&O seems to be very prone to tired capacitors and such aging problems, that are mostly unheard of in other vintage gear. Some of them cause particularly the computerized equipment to eventually malfunction, but many of them will just result in the sound getting worse with time.
I believe this difference is partly due to the physical design constraints, like space in the enclosures - B&O kit tends to be tightly packed and therefore runs hotter. Also, the components that were used were physically smaller - not many others used tantalum caps for example.
Another thing is the electronic circuit design. B&O engineers seemed to have a habit of using plenty of capacitors on the signal path. For example, the 5000/5500/etc Beomasters have the signal passing through about a dozen electrolytic caps from the line level inputs to the speaker, while the Japanese counterparts may have three or four! Some of this is necessitated by the electronic switching and control as opposed to mechanical switches and potentiometers, but anyway, this multiplies the aging effect due to old caps.
I believe you might be pleasantly suprised if you recapped some of the amps - and speakers! - in your collection.
