Thanks for posting that. It was interesting right up to the final paragraph where he says, "Having said this, I must say that in the other extreme, I also see no need to go insane with hyper-extended filters like the 1M-tap Hugo M Scaler because practically, that appears to be way more processing than is needed!". Unfortunately that betrayed a lack of understanding (or desire to understand) the algorithm which underpins the Hugo MScaler and which is not just a filter. But that is Ok, he will hear an MScaler one day and will then know what all teh fuss is about. Ears do have uses after all!Here you can see that all filters have advantages and disadvantages which are audible and clearly expressed by the measurements:

With HQ Player and the DAC's filtering defeated try comparing minimum phase, linear phase and asymmetric.

Thanks also for mentioning "The Astounding Eyes of Rita". I have and really like "Blue Maqams" and so I will try "The Astounding Eyes of Rita".
