Mushroomsound

I recently picked up a pair of 1979 klipschorns. I’m currently powering them with a Sansui AU717 but want to switch to a tube amp. Am currently deliberating between a decware zen triode, and the boyuu range a10 or a50 300b. Am open to other suggestions of course, but curious if anyone out there can advise / explain the differences I’m likely to hear with my k-horns using these different options. Thanks!
