I have the 4BSST and pair it with Focal/JMLabs Mico be's. I detect no cold, hard grainy issues at all. I have also run this amp with the Focal 927be which is a floorstander (limited production and precursor to the 1027/1028be current models). I have a small room and both setups worked very well. Some of these "be" Focals have become pretty good deals especially considering their original prices and the performance you get. FWIW my collection contains many of the same styles you list as program material.
Nice amp I love mine; you have many choices in compatible speakers and now you have another to consider.
