I usually read the comments that precede mine in an effort to avoid repetitiveness, but not this time. I'll simply say that a somewhat darkish sound may just give you the romantic sound you're looking for. In fact, I more often than not hear that kind of sound at live concerts as opposed to the squeaky clean neutral sound that numerous lovers of reproduced music voice a preference for. Air Tight and Joule Electra (mentioned in your list above)will point you more in the romantic direction than, for example, Supratek. At least that's been my experience, since I've previously owned Joule and Supratek, auditioned Shindo Masseto in my system and have long owned Air Tight. Of course, I can't guarantee your outcome, as you'll have to work on achieving your own desired synergy.
