Levinson 360s + Sony 9000ES ?

Recently I had achance to a-b 360s and the 9000ES under different conditions. The 360s using Transparent's Ultra xl
and the Sony using Reference xl V which I know is used for tubes output stages. This is the only cable I could get my hands on for this test. Is it me or I can't believe my Sony
9000es was better than the 360s under the conditions I descrbed. My questions Is would I be better off upgrading my interconnects coming out of my Sony 9000ES or keep
the 360s and upgrade at a future date the interconnects?
