"A used Aleph is a possibility, but those are getting fairly old and I wonder about maintenance issues."
Those amps are made pretty well. If you need more power, it would probably be a better choice. I had the 0 and was rated at 40 watts/ch. It was a very powerful amp. It easily drove my old B&W 802 S3's and my Martin Logan SL-3's. I put it next to the 3 and the 5 and it definitely had more power and I thought the sound quality was better as well.
