I've got one of those class A Accuphase amps.
Had to install 2 bridged coal furnaces in the basement to generate enough electricity to run it then 2 more bridged out by the pool to run the ac to cool down my room.
I can't tell when it's sunny out anymore and I think the wife and kids all might have lung cancer.
It's pretty cool how it glows that bright orangish-red and pulsates like a lava pool to let me know it's all warmed up and ready for some tunes.
But it sounds terrific! So, definitely worth it. Oh yeah, worth it, worth it, no doubt about it.
