Speaker selection for Cary 2a3i integrated


I have a cary 2a3i integrated amp.The amp produces 15 wattsof triode power. Am currently using a pair of Jamo concert jubilee speakers but have a hankering to try something different. Any recommendations would be greatly appreciated.

How about something from ZU Audio? They have pretty much all price ranges covered and theory speakers are extremely efficient and were made for tuber amps.
