just a suggestion, for an affordable, yet true ’reference’ level amp, i think you would do well with a smaller hegel integrated (use the amp section, not necessarily the dac section, though if a current gen model, that can also be used) - h95, rost, h120
msrp $2000-3000 - hard to do better for top tier uber clean pure sounding amplification with exemplary bass control, hegels will make sure all tested speakers are well driven and are not artifically being affected by an amp’s flawed ability to deal with odd loads and current delivery demands
