This is a question for anybody, whether the upsample button is depressed or not the locked in light will stay illuminated , is this normal. Also I am using Opti1 and the 44K1 light is green but none of the other lights come on, is this normal. The manual that comes with it is a little vague on operation. On the plus side the music has just taken a big leap forward which is very rewarding. Everybody who has a stereo should own one of these baby's.
