Hypex N core module

In what would be considered a "relatively affordable price range"...what is that then differentiates the Nord Acoustics from a PS Audio Stellar 300 from a Merrill Audio Taranas from a Benchmark ABH2 as they all have been given accolades for great sound at less than the price of a small car??

If you look at the specs for a Merrill tarranis which uses an ncore module for class d output they show bandwidth to 50 kHz. If you look at the ps audio stellar 300 which uses an ice module and bandwidth to 50khz. The benchmark ahb2 is shown as a class ab/h not class d but class d efficiency and bandwidth shown to 200 kHz. The first watt f7 class a with bandwidth shown to 100k. All of these Amps are well regarded and carry the designers name and therefore affect his reputation. Is it possible that the difference is the difference in the voicing.... sonic signature that each designer intends based on their hearing and memory of music??
