How would anyone know? I suppose if you had two identical players, one with and one without, you should be able to identify the difference. All such filters, over-sampling, NOS, filter or not, are controversial and are just different trade-offs for a so far insoluble implementation problem. Look at the NOS versus OS debate for example. Neither can be proved right, but some say they like one over the other and opinions are divided, but I reckon its all about the implementation.
What is more, I understand the apodising filters used by Meridian and Ayre are different to each other. The apodising filter, to make a gross generalisation, offers lower pre-ringing at the cost of increased post-ringing and poorer phase fidelity. Its another trade-off. I am skeptical that we will all prefer an apodising filter. My view is that an apodising filter will just be another variable that can be used, or not used, to implement a DAC, and that the art of the overall implementation will remain the more important issue.
Like you, Rhljazz, I am interested in hearing about the apodising filter artefacts compared with normal filters and with no filters. I don't think there is any reason, notwithstanding the reviews, to believe that an apodising filter is some kind of silver bullet. It is just a different trade-off, with its own set of downsides, that some of us may like.
