Neil Gader's Plinius Hiato Integrated Amplifier Review

Neil, thanks for the review, I read it earlier in tas, but just noticed it was posted.  In the review, it's stated that
"Under the proper circumstances—paired with an exceptional loudspeaker and source components—only a handful of competitors can challenge [the Plinius Hiato Integrated ]."
Can you tell us which competitors? 
Also, have you had the opportunity of comparing it to the Boulder 865?
Thanks,
Daniel
