Hello J, we've exchanged thoughts before....I use both the gear you have and tube stuff in my rather complex system. As was said above, you should not mix your kind of Spectral gear with tubes. It will sound just plain awful. The advice given above, to listen to an entire tube system is excellent. I'd also lend the Jadis gear an ear. By the way, should you ever want to discard your 360's, drop me a line. I'll buy them from you, if we can agree on the price.
Happy listening,
