The Adagios are more open up top and are effortless and very musical once they have some good hours on them. They do not have thunderous bottom end especially in a larger room but the bass is respectable and not boomy or bloated at least in my room. The magic is in the midrange of this speaker and they definitely shine in this regard. Ultimately they just sounded right to me and without spendig a ton more I couldn't find anything that I liked better. They should work well with either amp, I have used mine with a hybrid integrated(DK) as well as solid state(LFD) and they worked fine with either.
I should also mention that I enjoy similar music to yourself and although I bridge off in all directions the Adagios handle anything you want to throw at them quite well. Not a speaker for metal and so forth though I wouldn't think.
