In other words, no.
I have heard the Audio Note, Vitus and own the NuVista 800. The Audio Note has limited application due to its limited power and exorbitant price. The Vitus is excellent and my second favorite, but again, a little more power would be nice and the price increases here in NA continue to climb and climb. The brand is also, unfortunately, poorly represented here.
I've been on a mission the past 18 months trying to find the ultimate integrated for my family room system. I've tried several, including VAC, Devialet, Musical Fidelity, Line Magnetic, Rowland, Vitus, Mc, ARC, and many others.
We can agree on this much, when I owned my Magico S5's, there was simply no better synergy/match than Vitus.
The NuVista 800 may not be the best, since there truly can be no "best", but given its price, power and wonderful sonic characteristics, it is a terrific piece and the one I selected for my speakers.
