I have a pair of Mcintosh mc- 501 ss mono block amps, in my audio rig. I swapped them out for a pair of Mcintosh mc-2301 tube mono blocks. The tube mono blocks made, the ss mono blocks sound like charlie brown, amps (flat and non three dimensional.) I did not here a change in the bass, but lower midrange had more body.
But be for the swap i thought the 501’s had great 3-d imaging. That is my experience with tube/ss amps. The tube amps are less watts. The speakers are jbl 4435 monitors. :-)
