Anyone use a Belles 150A to drive a difficult load

I have been driving a large ribbon-hybrid (Flatline 175's--you never heard of them) with a Music Reference RM-9 (tubes, 100W/side) and the amp really can't hanndle the weird load (down to 2 ohms)though , at low volume, the sound is beutiful. The Belles is not a high current design but current isn't everything. Has anyone tred to use this amp for Maggies, or other cranky speakers? I listen mostly to large scale classical stuff and value timbral accuracy and beauty of sound above all other considerations but I like dynamics and bass, too. I have a VPI 19-4, Moerch arm, Grado cart, Mod 3 preamp, Flatline and Luminous Audio cables in a 2300 cubic foot moderately dead room. Thanks, folks.
