Feedback on sound quality of Vinnie Rossi LIO with onboard amp module

Just wondering if there are any current or past owners out there who have used the VR LIO with its tube pre and mosfet amp module?  How does it compare in terms of sound quality to the usual suspects in top tier integrated amplifiers... pass, ayre, arc, gryphon, hegel, luxman and so on?

No need to comment on the build quality, how great a guy Vinnie is... and so on... those points are stipulated to and accepted!

TIA
