Pap,
Are you " Tasso" on the Australian site stereo. net? If so you have a very unique system combo, CSL with the hugh Soulution 710 amplifier. It's funny how I assume that those who have a CSL match it with a tube power amplifier ( as if there's no other choice, Lol). If your are Tasso did you try the Soultion's sibling preamplifier? If I have this all wrong I apologize for the mistaken identity.
Charles,
