My friends and I have through decades, chosen mostly used pre-amps, amps and speakers to attain a "system" sound. I have have the advantage now of upgrading to higher resolution/still highly musical sounding speakers and eventually pre-amps and amps. I spent $150,000 in 2019 building my custom listening room which permitted the setup of my 14 knob adjustable Von Schweikert VR9 SE Mk2 speakers in record time (1.5 hours) by the installer who quoted 5 hours minimum to 8 hours for set-up. Since this is my final home, I blew the budget when I moved in on a great acoustical listening room only. It has activated carbon pellet bass traps built into the walls (see my profile). Yes, the Legacy Signature IIIs are great speakers but the VS VR9s are better and even more enjoyable (they are able to open the subtleties of performances where they exist, especially in classical music). Don’t discount buying great speakers even if used and older. Just mate them to the best power amps, new or used.
P.S. I could have purchased virtually new B&W 801 D4s for a song/$16K but I don't like the speaker sound and they are power hungry. So I paid 3.5 times more for the VS VR9s with warranty, upgrades, etc.
