SET amp for Gallo ref 3.1

I am currently driving my my Gallo Ref 3.1 (with Gallo subwoofer amp)with vintage Marantz MA 1 monoblocs(class A). Preamp is McIntosh C220, analog front end VPI Superscoutmaster with a Shelter 90x, digital front end OPPO BD 83. I have recently become addicted to SET tube amplification and wondered if anybody had any experience with tube amplification for the Gallos. I listen mostly to orchestral music and Jazz at moderate levels (80-85 dB) in a rel. hard middle sized room.
