I've heard the LS40s with 5 systems (2 Onkyo sets, a Cambridge Audio set, a Cayin set, and a VTL/Onkyo mix), alternating between Xindak and Monster ICs/Cables.
These speakers seem to have a relaxed character, reminiscent of the stereotypical vintage sound (especially with the Xindaks, as these get a bit shrill with the Monsters). They were never honky or harsh (frequently experienced in speakers utilizing less-refined horn-loaded drivers). This set is great for soothing vocals and/or a reverberant presentation of instruments. I think most Filipinos who are into this hobby prefer that kind of sound, and that may be a very good thing for Beyond Innovations (if that market segment catches on to this product). AVShop / MLY has the LS40 pair available for audition.
Architectural Audio's demo LS80s sounded great with their Naims. PRaT was top-notch, while all other items were good to excellent, imho. I've heard higher-end JBL speakers, but they were never matched as well as this.
