Quad 99 would mate well- take the slight treble edge that generation Aragon tends to have while allowing the spectacular bass performance to go unimpeded.
Another option is the Proceed AVP- it is odd to mention a surround processor but I just did a preamp shootout and listened to 10 preamps in my room extensively and this one was second best and it has a incredible DAC section.
I would stay away from the Halo- it looks better than it sounds in my opinion and while it is not a bad unit by any means it cant compete with the best in this price range.
