KAB is stereo. Agree with Richard's points about transferring 2-channel.

I would say the KAB is the right concept, but I would prefer separate turnover and rolloff choices. 
Linked from KAB's website is a PDF of Gary Galo's review of the unit. Gary explains it in detail and 
shows test results. It's a good preamp. I'm a little leery of the hard-wired low-frequency rolloff, 
I can definitely hear a -5dB dropoff from 40 to 20hz, but otherwise it's very respectable. 
Definitely lower noise than my TDL Restoration Preamp.

To Richard's point about being conservative with gain and transfer levels -- make sure to transfer 
in 24-bit.
