Best amps for Usher X 718


I have McCormack separates running the Ushers and the sound is wonderful. However, I am considering replacing them with an integrated amp with built in phono section (MM or switchable) due to financial reasons. Any recommendations?

We have been using Audio Space Ref 3.1 with KT88'S in our demo room with both Usher BE 718 and X718 with very good results. Plenty of drive and a very sweet sound.
