One tip from me is to allow plenty of time for the refurbished unit to break in. After replacing electrolytics and other components, the sound can change back and forth during the first 100 hours of play, or thereabouts.
Hello, Join this facebook group, there's lots of people on there, a lot more knowledgeable than me on the quad 405, you can ask questions there. facebook.com/groups/QuadAudio/?ref=share
@@markgallagher0000 Hi, thanks for your suggestion. I’ve had Arcam amps (albeit not the one you mention) in the past and as far as the amps go feel Quad 303 and 405s far superior in every way. Each to their own!
