Rackon, do you find the Quattros emphasise the lower mid-range a bit? I am trying out the Quattros now (SPM ref for speakers) vs Bearlabs and Siltech silvers. Am using full sets from each manufacturer. I find (or am I imagining) that the Siltechs are a tad soft and "kindly euphonic" in the upper register, Bearlabs do not colour the system, and the Qs as above.
I had the same experience as you with Quattro vs SPM vs Red Dawn (never used BHeaven).
