rogue audio doesn't put the output impedence spec in their 99 preamp manual. at least it wasn't in the manual that came w/*my* 99... which is why i tried crossing the 99's outputs w/differing resistors. as i previously said, a 2.2k-ohm resistor audibly reduced the volume of my rig, when the rogue was hooked up to my 25k-ohm impedence crossover. *no* drop in volume w/the 2.2k-ohm resistor crossing the cary preamp's outputs, which is rated at 800 ohms output impedence. this is why i believe that the rogue 99's output impedence is at least 2k-ohms. i've asked pass labs for input on a 2k-2.4k-ohm preamp driving their aleph-3, & haven't gotten a definitive answer; i'll post it when i receive it.
