Hi All, Currently I own a Cyrus CD6SE, Rotel RB890 (Power Amp) and B&W CM7, my Rotel Pre-amp is causing one side of my new speaker sounds softer than the other. Can anyone suggest me a new pre-amp to complete my system? I normally listen to Jazz and Classical music. I am considering brand like Naim, Arcam, Cyrus, Roken or the new 15 series Rotel Pre-amp....
