I run an vintage system in my spare room and for me its fun.
my A/D/S L910 speakers are keepers for life.
I also love vintage Sansui integrated amps. AU 20000, AU 777, are some of my favs.
Sansui Tuners are some of the best ever made love my TU 9900. dream of TU-X1. I use the TU 9900 in my main system still, have not found anything that sounds better, note mine is fully restored.
Revoa Agora B active speaker system is another vintage speaker system that amazes me on a regular bassis. I don't think i could sell these speakers. very rare in North America. Each speakers has 3x100w A/B amps for each section. thats 600w of power in these speakers. Some of the best bass i've ever heard regardless of age.
