Belles 350A Reference Preamp Choices

Could anyone share their preamp combinations they have used with the Belles 350A Reference and what was good and what wasn’t a good match in their systems? I just bought the amp and I currently have it paired with a Mapletree 2A SE. I really like the combo so far but I have no remote on the pre. I have had a suggestion by the seller of the Audible Illusions 3A. I would like to hear from others who have this amp.
