Hi Disclord ,
Yes ,the Beosytem 6000 and 3400 are beautiful quad system in the meedle of seventies, but their price are very very expensive in 1975 ,for exemple :the pay by month in France was 2500 Francs (540 $ ) and if you want to buy just the beomaster 6000 the price was 4700 F (1015 $) without player record/speakers/commander and MMC6000.
My units are only CD-4 . Bang & Olufsen don't have another quad product ,but the video/tv integrate have the DTS and surround 5.1.
My old TV of 1986 have already the surround with 5 speakers and the sound .......B&O (special decoder electronic of the firm) .
I try again to put some photos : Beomaster 3400 , Beovision avant , ouverture ,penta
