Tube buffer between CD and amp!

For example, Blameless by you know whom... ;-)

He suddenly found that a volume pot distorts! However, later he found that it distorts due to non-linear input impedance of the amp... And wrote an article about that. :)

What happens when you add feedback by voltage to an amp? Right, it's linearity by voltage increases. What happens to the current gain?

Think... ;-)

Can you please write some details about this form of distortion? You say putting potentiometer before amp with LTP input is bad? I don´t quite understand....

Thank you.

Hi
Thank you Wavebourn for your reply.
But I dont understand what you mean, I'm sorry.
And I'm thinking very hard:)
