I think a nicely restored vintage receiver would serve you well.
That being said, you might consider a new or lightly used Yamaha integrated amp. Their new integrateds retain much of the tonal qualities of their classic 70s models, and are no slouches by modern standards. They also retain much of the retro styling. A lightly used Yamaha A-S1000 in silver would pair nicely with the Heresys and you can find them for under $1k. I paired my Heresys with an A-S500 for a while, a nice combo.
On another note, a decent tube amp really elevates the Heresys to another level. This results in a visceral, enveloping experience IMO. Something like the Cayin A50T would really make them sing. There’s one currently for sale here for $650. Don’t worry about the power specs. I drive my Heresys with 20 tube watts in a large room.
