As with any amp-speaker matching question it depends HIGHLY on your room size and listening levels. What are they?
I've had HE AN/Es (the Kit 3s) and they are wonderful with the Yamamoto 45 or any 45 SET if you can accept mild volume restrictions. In my very large room I could play at 85 dB or so; any more than that and dynamics were clearly suffering. As a matter of fact the Yamamoto importer loved them with that speaker as did David Cope, former Audio Note importer.
(A 'crazy' idea would be to get two and bi-amp. You would not really be getting twice the power but there would be an improvement.)
