im gonna be scum for this but here it goes,bag the tubes & get a mcintosh solid state amp,i have khorns & they sound fantastic with all 7 mac amps ive had them hooked up to,i tried them with other hi end ss amps & they sucked but with the newer mac amps you cant go wrong,i just got a mc122 last night & the 1st thing i did was put it on the khorns & it is sweet.
