Preamp

Thank you George, I greatly appreciate your clearing this up for me. 

Hi George, 

I use a few different sources, including analog tape. I have not tried connecting directly to the Krell amp, as I was told by Krell not to and that my preamp needs to have a minimum of 6 to 12 volts (DC)? Of output to fully drive the Krell 

Hi, The Nak is a fine preamp. I was told by Krell that it does not have the proper amount of DC voltage to fully drive the Krell FPB-600 to its fullest capacity, plus it lacks XLR outputs, which is a superior connection to single ended, i.e. Quieter and less noise. The problem I have is that a Krell preamp, does not have enough inputs to accommodate the number of sources I have.
