Concur with Chashas1. Most important is trust your instincts. I don't think you would go wrong with the P3ESR. This new design features the first 5" Radial driver from the smallest box in the Harbeth line which deviates from the older P3's and is something really special. One of my friends who uses the 40.1 in his main system bought this P3ESR for his study replacing the Totem Model 1. A very nice and musical speaker which sounded excellent on vocals and small ensemble music. Of course, do not expect deep bass from the tiny little box but for overall coherence and musicality there are not many small bookshelves that can rival the Harbeth at this price point. In fact, none even in the higher priced-bracket will sound like the Harbeth's midrange. The C7ES are a bit larger and do offer a *slightly* bigger scale and deeper bass but can't handle big sweeps of orchestra or large scale ensemble either. The P3ESR are small speakers indeed, but they are small little gems.
Finally, the P3ESR comes in beautiful rosewood, and I thought they looked absolutely gorgeous in the finish compared to the standard cherry finish found in the bigger models(if this can be of further reassurance to you). I reckon anyone who ends up with a Harbeth, small or big will find long-term satisfaction with the speaker.
