After responding, last night, a thought came to me: I might bypass the two channel music mode, pre/pro problem by simply adding an analogue preamp. My amplifier has both balanced and unbalanced inputs (currently using XLR for the 990). I could run all my analogue sources through the analogue preamp, while running my sat box, Oppo 981 through the 990. This way, I might achieve the best of both worlds, possibly! lol

I've not heard of Audio Perseus. With my amp offering both input types, however, I could use any preamp I want, maybe! lol

Just a thought, another potential approach.
