I had L112's for about 20 years. I liked them best with a Classe DR5 pre and DR8 amp. If you could find a Classe integrated that would be a good match. Out of the group you listed, I would think the NAD C326BEE would be the best choice.
Eventually, the woofer foam surrounds rotted away on my L112's and I had them replaced with a rubber surround. They never did sound quite the same so I sold them. They didn't image all that well but they could really jam out. I can see why you would still like them. Good luck with the amp search.
