art audio volume control

can anyone chime in on the quality of the art audio volume control?

i have been seriously contemplating replacing my rogue99mag/caryv12i combo with one of joe fratus' works of art.
am i likely to miss the active gain settings of the rogue, which i'm somewhat accustomed to at this point?
or do you think i'll sell my rogue/cary pairing and never look back?

based on what i've read and the quality of output transformers that joe uses in his amps, i have been lead to believe that one of the high powered options in the art audio line would control and drive my tyler linbrooks to my satisfaction. i do like to rock out, but let's understand that i do not have much opportunity or reason to listen at sustained 100db levels. the linbrooks are a fairly efficent 93db and somewhat tame 4ohm load.
