I'm replying to my own post in case someone is searching for real world experience with this combo.
I decided to satisfy my curiosity and buy a single Aegir. It benefitted greatly from about 30 hrs of settling into the system (though I have no idea why equipment needs this, I hear it). I'm listening in a bass and vocal sweet spot 7' from the LRS in a 10x15 room. They are 3' from the rear wall and just under 2' from the side walls. The room has some GIK corner bass traps and absorption at first reflection points. The sound is rich and dynamic, with clean high end and solid bass. For this note I measured db(z) to gauge power demand for a couple wall-of sound tracks, plus a couple of the more spacious tracks I have in heavy rotation. My conclusion is that you can likely get higher volume slam from more watts, but this setup offers a lot of clarity, soundstage, and punch in a small room at modest levels. Calculated draw for my listening is from .1-11 watts, which leaves 70 watts headroom (theoretically). The amp isn't even warm. The Vocals are gorgeous, bass guitar and upright satisfy me (I'm a bass player), and the mid-highs offer lots of clarity on drums and guitars. I don't listen to a lot of classical so shouldn't comment on the needs of that genre, but for what I'm playing, it's a keeper and so nicely in my current budget. For context, here's a listening session.
Impossible Germany, Wilco: Avg 70, peak 80. Handles the dueling guitars perfectly.
Come As You Are, Nirvana: Avg 70, peak 73
Feel the bass drum, hear (isolate) multiple guitars, hear decay on cymbals, space around smack and tone of snare.
That's where I am, Maggie Rogers: Avg 73, peak 82
Easy to single out Octaves in fuzz synth bass, pulsing piano notes, extra vocal rhythms, autoharp, great lead vocal tone.
Baker street, Shawn Colvin and David Crosby: Avg. 69, peak 79
Lots of vocal tone — especially nice to hear Crosby in this sparse setting, lush reverb guitars and pedal steel, clear brushes on the snare drum
NASA, Adriana Grande: Avg 69, max 80. Able to isolate so many vocal layers, rhythm sound effects, distorted synth bass
You Go to My Head, Julie London: Avg. 64, peak 77
Spacious jazz session, soft sexy vocal textures, she overdrives the mic on a note.
Birds, Dominique Fils-Aimé, avg 68, peak 80
Pinpoint soundstage on vocals, double bass tone, hand claps timing all so clear.
I'm using a first gen Freya in tube mode and a Modi multibit with Tidal and a zen stream. Also a REL T2 (turned off for SPL readings above) that definitely helps the LRS, but they also sound respectable on their own.
