I have those amps and used them with spendor S8E's with great results,I now have them mated with spendor SA1's only because I like a smaller type speaker in my room and they go great together.I use el34 tubes in my amps not kt88's.Check out spendor,years ago I had vanderseen 2's and 3's placement was always a problem so the dealer recommended spendor so this is my brand of choice.
GOOD LUCK
