The past 2 months or so I have been on the same journey. In fact I've ended up with Audioengine A2+ speakers. The two others that really came in to play were Focal XS Book speakers (on sale at Crutchfield for similar money, not chosen due to dimensions), and PSB Alpha PS1's (read that they were more revealing/analytic, but I have no experience).
My goal with these was two fold: 1. be musically engaging at low volume (it is a work PC in a private office, but I can't be so loud as to hear it across the hall), 2. Don't be so big that those that report to me would think they could bring a boom box in and setup shop.
The first goal was achieved, however it really came into its own when I downloaded Jplay to run on my PC through the Audioengine speakers. Jplay brought Hi-Fi (see files info below) that was not fully realized by just the internal AE DAC.
The second goal was somewhat missed. These things are obtrusive...I did not go with Focal because they were bigger yet, however these are definitely bigger than standard speakers. I am not sure the Focals would be much different of an impact. The PSB would likely be more fitting, but I really only steered away because of the overwhelming reviews by online sources and I bought through Crutchfield. Their advisor recommended either the Audioengine's or the Focal's. So I went with Audioengine based on reviews.
Lastly, I am streaming Tidal CD quality 8-10 hours a day at work...Can't recommend that enough. So my source is a Window's 7 Pro with JPlay and the Audioengine are connected via USB (supplied cable), and the files at CD quality.
Bottom line is that I am really satisfied...seriously my only complaint is that the music is so engaging that I get distracted from work. I am in a private office that others come into often. If I were in a home office you may want these for quite listening or if you are cranking them up the A5's would be worth consideration. Depends what your goal is for listening.
