How good is your hearing ? And how do you know ?

I suspect the vast majority of the older members on this forum will struggle to better 13k hearing tbh, no shame in that at all.
And does it mean I enjoy my system and music any less?
Heck no!
And does it mean I cannot tell Schiit ( sorry could not resist!) from Gryphon?
Heck no!

Two approaches: one - the worse the hearing the better equipment needed, another - the opposite.
And yet another approach - better equipment without paying any attention to the above.

Next stop Boomboxville! 🚂 Toot! Toot! What’s the diff, McGriff?

The vast majority of older members? You mean the ones over 80? 🤫
