Something to keep solidly in mind when reading about how wonderful this or that class D module is that the commentator probably doesn't have even a decent system and his standards are very low. That seems to be the general rule with people praising class D. You'll rarely hear anyone say, for example, they liked this or that module over their old Pass, Mark Levinson, Esoteric, Solution, Gryphon, Boulder, etc, etc. It's also bottom-tier entry level products.
I'm currently evaluating a VTV Purifi, and it's frankly not impressive. I'm not saying horrible, but my Odyssey amps (Stratos, Kismet) are better, and Odyssey is in no way a high-end amp.
