So I put on OK Computer to check out how good the phono stage is and argh mega distortion every time the music goes high or low. I’ve checked all my connections and they are sound. I’ve a worrying feeling that my poor old 14 year old Sony amp has given up the ghost. Please tell me it ain’t so!! I don’t want to drop another chunk just after getting the phono stage. If it is fuct what should I look at in the €1000 range. I like the look of the Marantz HA-AMP1 and PM8006. Any other suggestions.
