SPEAKERS...Celestion SL700SE
AMPS...Quicksilver 90 watt silver monos
PREAMP...Quicksilver LS model
Theta Miles CD Player
CABLES... Kimber 8tc/8tc bi-wire (speakers), Kimber kcag and silverstreak (interconnect).
You can do better with modern 1 box players IMO. I had a old Theta DAC and its just way past its prime. Try a used Lexicon RT10 Universal player, you will be stunned how good it is for under $500.
