I had Rogue M-120`s and had them "upgraded " to the M150`s. I preferred the sound of the M-120`s. Nevertheless, I have used both the L1 and L2 linestage and have had excellent results with both. Tube rolling with the Rogue can make huge differences. Same with the Audible Illusions. You`ve gotta pay for great tubes though. And there are a lot of fake copies out there. I`m 100% satisfied with the Audible Illusions linestages.
