I heard the DALI Helicon 400Mk.2 a few days ago with the Jeff Rowland Design Group 501 monoblocks, driven by the Rowland Capri. This is a truly smooth and revealing combination. I listened to Karrin Allyson, Rebecca Pidgeon, Livingston Taylor, Kenny Rankin, Chicago Symphony, Dallas Wind Symphony and the DALIs really shone well.
Prior to plugging in the 501s were tried a Primare integrated, which did a very poor job of controlling the DALI's woofers, yielding a bloated, bloomy bass. Next, we put in a Rowland stereo 102 and things improved a bunch, but the 501 really took hold of the Helicons and made them sound smooth, deep, detailed and lush, all at once. Those speakers evidently love a bunch of power and high damping.
