I finally found an amp that TOTALLY outclasses this classic monster amp. The amp is the VTL Reference MB 750 monoblocks. The power ratings are very similar between the CJ and the VTL at 4 ohms. However the VTL is much more relaxed, has much sharper transients, more natural midrange, produces low level details that make the Soundlab sound like a Soundlab, lightning quick dynamics, better dimensionality, and much more thunderous, yet well articulated bass. This is a HUGE LEAP.
I know there are a lot of folks of who like tube amps. I was not one of them until I heard one with enough power to drive a tough load and do everything else in addition to creating a natural midrange.
I am not selling the CJ because it is as good as SS gets. But all I can say about the VTL is: WOW! WHAT an AMP!!!!
