To be honest, I was expecting a 98-99 at this price range, but it is just 92.7? Can you explain why the NT-6 and NT-6 Pto are "better"?
First, the NT-6 and NT-6 pro have a very different sound than the PS-5 and if you would buy one of those two due to sound signature preferences, which is why people should buy, then those three aren't even in the same conversation. If you don't like the sound signature, it very likely could become an issue once you get used to the high level of technical performance.
My total score is comprised of several different characteristics including clarity, PRaT, overall soundstage presentation, transparency, detail, resolution, etc. as well as overall quality of the bass, midrange, and treble. The NT-6 and NT-6 pro don't score much better as the NT-6 is at a 93.0 and the NT-6 pro is at a 96.6. The NT-6 wins some and loses some compared with the PS-5 while the NT-6 pro is even clearer, more musical yet more detailed, and more dynamic than the NT-6, but in exchange it gives up the more accurate sound signature (which is not graded because it is like a flavor, personal preference). When a $550 cable is added to the NT-6, it surpasses the NT-6 pro, but then the price jumps also. Some day I will post all the gory details, er, I mean numbers.
We would all love to see those gory details.
