As an owner of Merlin for 5 years running, first, let me admit I am biased.
I was at the Show as well and would say that judging & comparing sounds at the Show is difficult at best. The set ups are sub-optimal, the choice of music sometimes questionable, and by the end of the day, you are just too tired to really make a good and consistent judgement. But one thing I will say, I came home to my setup (Merlin-VSM-Tube, Transcendent Sound OTL, Rowland preamp) and felt satisfied with what I have. Some setups at the show may have more bass, some more lush, but in the end, the Merlin does everything very well. Like a thoroughbred, the more you throw at it, the better it sounds. And when you throw junk at it (lesser electronics, bad recordings) it will let you hear it too. In fact, although I have owned three generations of VSM, it is the only component that remains from my original setup from 5 years ago. That says a lot in this crazy hobby.
