I've owned Modern gear, Tube and Solid State. Vintage gear sound better once restored, not including receivers in the list.
Owned a Marantz PM8006, Marantz 7T Marantz 16B blew it away. No comparison in detail, bass, musical enjoyment. I heard things in the recording completely masked by the Marantz PM8006 being $1500. Your looking at 8-10k for new gear to match at least.
Now there is a Marantz PM7200 that does class A made in 2000's Cap upgrades and upgraded the power transformer to toroidal transformer. Very special amp!
HK430 has amazing amplifier section, Add a tube preamp into HK430 with La Scala's. you would be in for a shock. :)
