OP has a freaking Paragon! If it’s mint it’s at least $25k. Vintage Marantz, Mac, Citation would be appropriate. Not some old receiver. The Paragon was expensive when it was new, it’s was always paired with the good stuff.
Top vintage receivers vs. modern high-end equipment
I am considering pairing an old amplification system to my JBL Paragon -- the idea of getting an all vintage system is very attractive to me. Among other things, I am looking into classics such as the Pioneer 1980 receiver or the Marantz 2600. Does anyone have direct experience in comparing this kind of equipment (very high-end but 40 years ago) to current high-end equipment, imagine an integrated Pass Lab amplifier? How do they stack up? Thank you.
