A Case for Releasing Analog Recordings in High-resolution Audio

You know I hear this a lot.  I would even think it a good use of the extra spectrum.  Yet few indeed are the ADCs or DACs that work like that.  Most have a 2050 hz transition zone at 44.1 khz and 4100 hz transition zone at 88.2 khz.  So and so forth.    The flat band should end at 25 khz or no more than 30 khz imo.  Lavry gear does this, but few others.

A sharp filter at 20 kHz just might make an audible difference. The same filter scaled to 40 kHz will be a lot less audible since any nasty effects (ringing, passband ripple, etc) are well removed from the audible range and there is generally less content at those high frequencies in the first place.
