I have a pair of A23s among the components I should sell. I thought they sounded a bit anemic compared to the A21s. I eventually moved to JC-1s for mains and used the A23s for surround. If you can manage it, I'd look for a used A21, a really nice amp.
Amp for Magnepan "Mini-Maggies"
I am planning to use a Mini-Maggie system as a whole-room setup as per the discussion in TAS (link below). I wondered if anyone has tried this and if so, what size amp they used - or would recommend? I was planning on driving them with a Parasound Halo A23 (225 Watts/channel at 8 ohm & 45 amperes peak per channel) but wondered whether this would suffice. Maggies always prefer more power but the discussion about using the Mini Maggie system in a whole room setup specifically mentions the need for a powerful amp. Any thoughts or suggestions are welcome!
