I've compared this amplifier to even the mighty EVO-900e mono block.  The Solo 575 has an even lager soundstage (width and depth), there is noticeably more transparency, more speed, and an excellent control from top to bottom.  iBias is more precise, less smeared, and more listenable than all previous Krells.  The Solo 575 is non-fatiguing, and quite simply the best sounding amplifier Krell has ever built.  And these amplifiers have RCA, XLR, and CAST!  Paired with a CAST-capable preamp is just sonic bliss.  The other welcome feature of this amp is the low heat output.  They are very efficient.  Krell iBias rules!

From Stereophile September 2015:

"The Solo 575s' taut bottom end produced always-entertaining rhythmic drive and pleasing musical flow. Their punchy but nonaggressive top end was likewise fast, and the surprisingly silky ultratop, which appeared when least expected and was always very welcome, added to the endless excitement and strong listening involvement these amps produced in me." 
Krell Solo 575 monoblock: $22,500/pair
With their top-of-the-line Solo 575 and its similarly new stablemates, Krell has made a conspicuous return to class-A amplification, but with a twist: Krell's iBias signal-tracking technology is claimed to make possible an amp that runs in class-A yet takes up less space, runs cooler, and delivers significantly more power than class-A amps of yore. In MF's system, the 575W Solo 575—which offers balanced (XLR) and unbalanced (RCA) inputs as well as Krell's proprietary CAST input socket—produced not the richness, suppleness, and maxed-out sustain he associates with traditional class-A amplification, but rather a speedier attack and a "taut bottom end [that] produced always-entertaining rhythmic drive and pleasing musical flow." As Mikey says, especially if you listen mostly to rock, "you need to hear the Solo 575s." JA noted that the Krell inverted the polarity of signals appearing on both its XLR and RCA inputs—and observed power output that comfortably exceeded the manufacturer's specifications. His conclusion: "Amplifiers don't get much better."
