McIntosh ma6900 a proper preamp to a Decware zen triode single endled tube amplifier?

McIntosh ma6900 amplifier, 1982 khorns updated with volti audio gear. Am thinking of acquiring a Decware triode single ended tube amp to get the tube sound with the khorns which are now sensitivity of 104db. Would the McIntosh amplifier be a proper preamp? Everything I have read does not make this sound like a good pairing. I am not a techo-geek with any special knowledge.. I just buy what sounds good to me. Any thoughts or references which might provide more information than I have would be greatly appreciated.
