Just my two cents,
1. Has Amp technology, outside of digital or class D, really advanced that much? I personally do not think so.
2. People spend thousands trying to replicate the sound of "golden era" components. Maybe more so on the recording side of things (mics, compressors, analog tape, etc). However, people seek the "golden" sound of tubes, speakers, etc as well
I would send in your components and let VAC give them a go-over. IMO, you have endgame equipment.
