Speaker selector app.

The app should have a footnote*

*Unless you have deep pockets, and a LARGE dedicated listening space, allowing tested and determined speaker placement, seeking extended bass is unadvisable!

Once you have learned to listen, and have a small set of CD's (your source) that reveal ___? to your ears, the need for instant speaker selector comparison is not needed. It is also not good practice to have inert speakers in the room when listening to others. 

I remember an audio shop in Brooklyn Heights, back in the late 60's, the innovator of only having 1 set of speakers in the listening space. They had a few different size listening rooms. A storage room of speakers and dollies to go down the hall for consideration. That frees up placement options and omits vibrations of other inert speaker's cones, etc.

Anybody remember their name?

thanks, that sounds correct, including someone else being Elliott. You seem to know the different spelling as well as Kasey.

I was only in the store, drop in without an appointment, a few times, just an impressive memory.

I didn't have much more than interest then (not interest on money, no spare change then).
