I wish I was more familar with your speakers, but I'm not. I am familar with these amps and I think the PL3/5 offers you the best chance for success. If for no other reason that you have a lot more flexibility in not only selecting the different types of power tubes but you can fine tune it by changing the small tubes and the rectifiers in the pre-amp and amp. I use the PL3/5 combo for the bulk of my listening and have ultimately chosen 6L6GC's in preference to the EL34's, 6550's, or KT88's I have on hand. I've had them now for over 3 years and have had zero problems.
Good luck.........
