Old design that were good and at the roof of Audio world many decades ago are always very good even now...My Sansui Au 7700 beat the crap of many more modern amplifiers....But never mind your amplifier....
Why?
Because the secret of Hi-Fi is way less in the hands of the electronical engineers than in the hand of the acoustician....
Speakers drivers-room and ears brain are ONE.... The amplifier and the DAC are externally linked to this One system...Music flows with the sound waves...The electrical signal is a signal not a sound....
Most people has never listened to the true potential of their own audio system, vintage or not, because the acoustical field of their room is not up to the job.... It takes me many years of home experiments to know that first hand.... My best....
