I have owned SF Olympica III's powered by a Mac MA6900. Harbeth Super HL5 Plus powered by same and currently own Magico A5's powered by MacIntosh MC275 Mk V with a C2300 preamp. I also have a B&W DB3D behind my rack firing to the side walls (think Phil Zone). Best and most satisfying system I have had.
Side note / big vinyl fan with an Aries 3 and audio technica Art 9XI. Streaming BlueSound Node 2i through a Mac MCD500 (also plays SACD). Similar size room with 12 foot ceiling. Happy to send pics.
