Congrats on your choice of the Treo CTs.
I was going to say, if you have heard or owned a speaker with a certain ’sound character’ that you like or know that you will miss if you don’t have it, that goes a long way in a future decision. The old saying ’we like what we know and we know what we like..’ A reason to choose outside of that ’preference’ is if you want an entirely different presentation or sea change in technology/upgrade.
Another way to eliminate speakers from contention is to understand what you don’t like (and especially the midrange reproduction). Ie - I have always liked a [midrange] speaker with a paper based driver. I know technology has improved greatly, but over the years, I could almost tell you I wouldn’t buy a speaker with a metal or polypropylene cone midrange driver, regardless of how well it imaged or how accurate it measured..
Staying within a brand you have owned and liked is a safe choice. Enjoy.
