Loving my tube Preamp, Class A amplifier. Whats your favorite amplifiyer combination?

I have had my Class A "Aegir" amplifier(s) x2 running in mono purchased about 6 months ago, combined with my Audio Research LS 25 Line Stage Tube Preamplifier and have been loving this combination. This is by far the sweetest sounding stereo sytem I have owned. These are couples with my Wilson-Benesch Square 2 speakers and REL 5/Tx (x2) subs. What combination of separates has re-energized your love of music?
