I cannot compare to the Rogue because I haven't really heard it. I can tell you, though, that my experience with the 350A has been quite different from Bob's. I use it with my beloved Mezzo Utopias and I chose it in part because, in my system, it is anything but dark. I find it a little cool and analytical; exactly the sound I am seeking in my music system.
That being said, I don't discount a word of what Bob wrote. Components interact in odd ways for complex reasons that we don't even begin to understand. For that reason, I am always dubious when some enthusiast says, "You MUST get the Ear-O-Phonic 2000, it blows EVERYTHING else away." Well, maybe it does...in that room...with that equipment...for that listener.
Listen a lot. Buy what sounds good to you.
