Single ended Power amp recommendation


I just recently purchased a pair of SAP J-M2001 MKII and need to change my power amps. Currently using BAT-DK5 to Emotive Audio Sira LE and Conrad Johnson Premier 8A.
Since the SAP are horn speakers, I heard that it should be best with single ended poweramps w/ zero feedbacks. Any suggestion and recommendation?
I'm thinking to sell my Conrad Johnson Premier 8A so the budget should be around 5-6k.
Thanks!

Rgwrjs,
from all the amps you've tried, which one you prefer the most?
The SAP J2001 MKII has 97db instead of the older version, which have 99db.

Thanks
Also, another question I hope someone can help me with. How would you compare the 845 v.s. the 300B.
I've expirience the 300B (Cary 805C) and loved it. Heard a lot about 845 so just wonder....

Thanks
30 watts is more than enough power for any kind of material for most speakers with a 99db efficiency rating....10 watts would be plenty
300b sounds better...for the best sound with 845 amps you would want top notch NOS tubes...budget at least 1000 US for a pair of NOS 845 tubes..they are much more expensive than quality 300b tubes (300 to 400/pr..sophia, TJ)
