krell audio+video standard pre/pro?

hi, i know this preamp is way back in 96, but i'm interesting in a processor with a class a preamp which this unit has, woundering is this preamp sounds good for 2 channel too? please advise..thks
I never was able to hear the av standard....but i have been using a showcase for many years strictly as a two channel preamp and i couldnt be happier.
