John Bamford of Hi-Fi News (Aug. 2013):
"...we were both taken aback by the amp's refined presentation. Neither of us expected it to sound anything like as controlled, dynamic, squeaky clean and transparent to source recordings as his pair of mono'd Devialet D-Premieres, that's for sure. Nevertheless, these two wildly different designs shared some important traits, allowing the loudspeakers to develop a fabulously deep and wide soundstage, brimming with loads of details and all underpinned by tightly-controlled pulsating bass information..."  Check out the entire review

"...while definitely not a candidate for the new Stereomojo column “Audio for Cheap Bastards,” the KR Audio SXi Mk II integrated amplifier, gives us a taste of what state-of-the-art, no holds barred, modern amplification is all about. While there is no way that I could seriously consider owning an amplifier like this (at least not at this point in life), I definitely appreciated it and savored my time with it… That is, once I figured out how to keep and feed it! If you take your time to optimize whatever comes before it in terms of source component(s) and interconnects, you will be generously rewarded with some of the cleanest, fastest, most immediate and dimensional sound you could ever want. To boot, it’s also a visual statement, especially with those beautiful T1610 vacuum tubes up front. If you have the bucks, it would be hard to do much better, and you could certainly do much worse spending as much or more. Watch your back though, it is a BEAST!" Check out the entire review
