Sharing my history I moved on from a Rogue Audio Cronus Magnum II into a foray of separates-
(2) rogue audio tube preamps, rogue audio, parasound and pass power amps, cary audio tube preamps.
truth be told I miss the sound of the Cronus Magnum integrated. The only thing it was ultimately missing is that last ounce of speed and dynamics compared to my current tube preamp / solid state amp. But the overall sound was often simply gorgeous, something hard to find regardless of your system.
