Hmmm. You must really like a super warm glossed over sound with little detail. My adcom was much warmer and duller than my classe but i had the 555mk2 so maybe there really different, but if thats the direction you want to go then you should consider the mk2 or 5800. If the 555 is somewhat bright then it would be a great match for the vandersteens since every pair I have ever heard is super dull and lifeless. I'm not trying to be negative i'm just relating my expierience with these products. So I hope this helped a little.
