Very interesting analysis. What have you done internally, with you Ncores? I used the largest gauge I could fit, that would allow me to bi-wire each monoblock and then bi-wired these to the speaker. I believe that Bruno, from day one, has noted this produces the best sound. While certainly not as scientific as your analysis, it would potentially produce similar results (assuming you used the lowest gauge possible, given that you have four speaker cable runs going to each speaker, from each mono-block?
