Hi APDOC, my absolute reference amplifier is the new Rowland M925 4-chassi monoblock. See:

Concerning class A/B Rowland M625 300W stereo and Veritas 400W monos.... My M625 was a very early unit that lacked the benefits of some key circuit enhancements derived from M725, which JRDG incorporated in later M625 production units.
Predictably, Veritas monos with their higher power delivery excell in authority, size of both sound stage and instrumental images. Both amps are excellent at controlling difficult to handle treble "jaggies" in complex sostenuto passages and coherence of bass, but in this arena Veritas was superior to my early M625 unit.
