Speaker selector app.

IMO the Niles speaker control is not the best solution.  If you want to seriously compare speakers I suggest you get one of the Luxman speaker selectors - see here:  http://www.luxman.co.jp/product/#accessory (turn on Google translate).  I use the AS-50R and it's great.  Very reasonably priced on eBay - ships from Japan.

If you want the best product for speaker and RCA switching there is the ABX Switch Comparator made by Van Alstine:  https://avahifi.com/products/abx-switch-comparator

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?

I am not looking for a manual speaker selector. I'm looking for an app I can run on my phone that I put in criteria of what I want and it suggests different speakers to me.

And you think you’d get better recommendations from an app than you would here why?  Sorry I wasted my time here.
