Assuming from the press release that this is an apodizing filter that 'removes' Gibbs effect preringning... how many peer reviewed studies can we compile here below my post that indicate anyone can hear these 'artifacts'?
Ready, on your marks, go!
Be careful of publications from the businesses that are pushing these filters (eg, Meridian audio / J. Robert Stuart). AES papers count only if the results have been independently reproduced (the AES is in the business of publishing 'interesting ideas', and the papers run the gamut of careful science to raving lunacy).
"I listened and _totally_ heard a rounder, fuller sound with better staging" is not data. It's what audiophiles have said of every nonsense breakthrough of the past 40 years. The one true breakthrough, digital audio, they generally still roundly pan and feel the need to 'fix' by sprinkling fertilizer all over it. It's like holy penguin pee, only it smells bad.
'Proofs' and explanations are nice, I indulge in them myself, but the blind listening data is the final authority.
