Many here at ASR are familiar with Dr. Toole's excellent work and book. It's cited often, including the concept of the 'Circle of Confusion' that results in inconsistnet recording quality. He also posts here himself.
The OP (who effed off years ago) was bizarrely claiming he couldn't hear the kick drum in many recordings. The excerpt is about excessive digital compression and frequency bandwidth limiting generally, not kick drum per se. In fact such tools can be used to either de-emphasize or enhance kick drum. The OP was citing stuff recorded before digital compression even existed. And posters here pointed him to good masterings and well-recorded kick drum.
