Hi Murphythecat, I hope it is ok if I will answer here the pm you have sent me yesterday.
My experience with the Dynaudio C1 is that they sound a bit nasal when played below 70-75 dB, but open up complete when played between 75-80 dB. In smaller rooms, the bass can be problematic with them, i.e. too little at low volumes and too much at higher volumes. However, if one is able to overcame these bass issues, the C1s will sound with most types of music more intimate and fuller than the MicroBe and will also image better.
Regarding the Focal MicroBe speakers, IMO in smaller rooms they are a safer bet than the Dyns. If one is willing to take the time to position them properly (requires rather exact measurements) they will yield a stereo image almost as good as the C1. They are easier to integrate with a subwoofer, and I would certainly recommend to anyone to complement them with a subwoofer, viz. not because they lack bass but because by doing so one can get world class full range sound out of them. I did not find they lack coherence (I was sitting at around 7 feet from them.)
The Vivid Audio V1.5 speakers are indeed very good speakers. IMO they are significantly better than Dynaudio C1 and Focal MicroBe. They have better timber, are faster, more coherent and more detailed than the C1 and the MicroBes. They have decent bass and, because of the horn loaded tweeter play wonderful music even at low volumes. I would go so far and say that the V1.5s are in the same league with the likes of Raidho D1. They would certainly be my pick.
Finally, I should say that when compared to my current Avantgarde Uno speakers, the Dynaudio C1 and also the MicroBes speakers sounded boxy and extremely slow. That experience really made me reluctant to recommend anymore the Dynaudio C1s and the Focal MicroBes speakers (even though I have had wonderful times with both speakers.) Vivid audio speakers, on the other hand, do not sound like drives-in-a-box. IMO they are among the very few speakers that do not exhibit this weakness. In fact they are the only speakers I have heard so far that did not sounded like drives-in-a-box, and this include speakers like TAD Evolution, Raidho D2 and Focal Grande Utopia 3 EM.
p.s. I did not have the V1.5 in my room (only the Giya G3). However, I have spent 3-4 hours all by myself and with my music in a dealer room with a pair of V1.5s (which I was told were well burned-in).
