most important components

Neither component is important, because none of them can play the music on its own:-)
The exeption is to console stereo in one box.

I went to an audio show several years back where I listened to a beautiful Italian made SET amp played thru a pr of very expensive single driver Beauhorn speakers. The sound was to die for;

I remember going to the private high-end seller that demoed his Beuhorn speakers and it seemed to me that I couldn't even give even $50 for'em. They could only reproduce vocals. The rest is total mess. They were demoed with top-notch Platine Verdier TT, Heron tube phono and Viva amp. JBL 4312 at fraction of price would do substantially better full range job.
