Audiolabyrinth, no preamp manufacturer would get very far if their preamp had DC at its output! Any preamp manufacturer has to deal with the fact that their preamp will be used with a transistor amp that is direct-coupled from input to output.
A DC level at the output can cause all sorts of problems, and not just for transistors. If a tube amplifier has a direct-coupled input (our amps do and many others do as well), a DC level at the input would cause the input circuit to make distortion and could adversely affect gain.
So it is simply something that preamps don't do! That is why I said earlier that Krell was promoting a myth.
Preamps, *all preamps*, do not have DC at their output. It does not matter tube or transistor.
So the Krell person you spoke to who is looking for 'documentation' need look no further than this post. No manufacturer in their right mind would make a preamp that puts out DC. It is literally that simple.
