That is always the problem with listening events: the room.
I am usually a bit more forgiving with issues such as the ones you refere to Steve. In my minds ear, I really try to "extapolate" the sound a bit. If I cannot find anything fundementally amiss or off, then I will be willing to conceed that any "errors" are room generated. Without such "forgiveness" all shows and the like would unbearable.
It was, afterall, such a setting that I first heard the Parisafal Ovations, so there was enough of a glimpse into their signature to want to seek them out over and over again unil I becam an owner.
I did not find the bass boomy at all. However, I was front room off to the stage left (next to that couple who should have "got a room"). In that seat, I found the bass to be tight but short of viseral. I had to leave before I think John got to more aggressive decibles, perhaps there was more thunder after I left.
All in all, an excellent product which, I am sure, trickles down the line. It is the same ribbon in the Sarastos II as the big boy. With that event, I can say that I have heard all Verity products save for their sub and the Renzi and contest that there is a soothing tone all through their line that is to die for...IMO.
