i have the hegel 590 and using its internal dac, the sound is very neutral (not warm) with very flat treble response... that along with your magicos and silver cables can lead to a sense of brightness, especially with the innuos front end
when listening to the ayre qb9, your use of silver interconnects may also contribute to the sense of forward aggressive treble
this said, i would suggest considering of any of the following (two lower priced, three higher priced, if you are patient you can find them used)
good luck!
1) a modwright tubed cambridge cxn v2 streamer/dac
2) a well modded mhdt orchid tube buffered dac
3) an msb analog dac
4) a chord hugo tt2 with m scaler
5) a mojo audio mystique v3 (or higher)
all will provide excellent clarity, soundstage and openness, but with a sense of ease through the treble region and overall musicality that is superior to the internal dac of the h590 -- all also will bring a real magic/palpability to voices such as melody gardot, chantal chamberlain and the like
