Got both pairs of speakers yesterday and hooked them up this morning. I'm no veteran, but my impressions so far:
- Sierra 1 - these are on a different level to what I've heard before. There is detail, clarity and an openness that is incredibly exciting. Instruments are very well defined and separated. I don't find these warm or bright, but just very easy to listen to. I ended up with a full toe-in with these. They are about 7 feet apart and 7 feet from me.
- Borea BR08 - these guys are bigger than I expected. Solid build, even if basic. They are more sensitive than the Sierras and create more of a "wall of sound" in my room. However, the sound quality seems more similar to my Infinity R162s, just bigger and more defined.
