Let us presume that this is an enthusiast forum and a lot of us have some ’over the top’ gear.
On the topic of speakers, my observation has been that one needs a huge room and has to be listening at rocketship level spls to truly "get their money’s worth" with the flagship speakers, for example...Infinity IRS, the big Schweikerts, Borresen or even my former TAD Reference, etc. Otherwise, their potential just feels unused.
At rocketship level spls on dense tracks, they can continue to retain their composure and fidelity levels. But, I certainly don’t wanna go deaf and I’ve never had the type of ceiling heights, etc that do them justice.
For example, i always felt that PS Audio’s ’reference room’ was too small for those big infinity speakers.
Another example, there is a guy on YouTube sitting around with 'over the top' flagship gear (you know who) in a repurposed garage with his back right next to the wall (facepalm).
After scaling down with the ’below flagship’ level, their potential feels maximized with the rooms i have and spl levels I listen at (On that note, i still probably listen louder than most guys on this forum).
