I am curious what technology of volume control is used in Pandora.
I like the concept of KX-R or Accuphase 3800 volume controls, rather than simple chip in Audio Research s.
Volume should also operated in true balanced mode, like Accuphase C3800.
For KXR concept of maintain performance at any level is interesting, while I dont like it to have moving part and mechanical contacts, but I heard similar click when operate Pandora volume too.
