It is not well established people can hear any of the problems that Ayre marketing paper talks about. These funny impulses that need the magic Apodizing show pre or post-echo in music material and ONLY happen above 20kHz. So these fancy pics tell it is pre-echo but leave out the fact it is happening at low volume and high frequency. Now when you create a 44.1 version of your hires material with resampling that doesn´t produce pre-ringing and you magic filter it afterwards you even harm the signal. These filters are non-linear also. Benchmark Media is another audio manufacturer that clearly states this pre-rining is a non-issue to them.
