Well most feel it doesn't get any better then soundlab with tubes for the "disappearing act", though they take up more room then most can afford to lose. Also Avalon Acoustics, are known for there disappearing, this has been covered mainy times before and always the same answers, so there be a few more but they slip my mind(what's left any way) at the moment. I own avalons and love the "jumping" around they do, its pretty weird, in particular after you have a few into ya, nudge-nudge if you know what I mean :)
