This may be too late to be helpful, but here's my two cents on the issue. I owned a pair of Soliloquy 5.3's, and now have a pair of 6.2's. I have enjoyed both sets immensely. They are one of the most natural and accurate sounding speakers I've ever heard. Placement is key, as is break-in. You will find that for several hundred (yes, hundred) hours, they will sound bright and perhaps even unbalanced. You might even wonder what this bass response is that people have been talking about. You will notice this even more if you bi-wire them. But once they have broken in, you will be stunned at how engaging they are. They simply disappear into the room. I can listen to these all day long, and they don't seem to be coloring the music at all. The 6.2 has noticeably more bass presence than the 5.3, though not a huge difference. I have played a number of amps through the Soliloquy's, and all have been quite satisfying. Currently running Quicksilver Mini-Mono's (25WPC), and they just sound perfect to my (and my wife's) ear. I cannot recommend these speakers enough. From vocals to jazz to rap, they cover a lot of ground with an honest, warm sound.
