jafant,
Still alive and kicking, and enjoying my system more each day. IMO, the 4B cubed is an excellent choice for the 2.7s.
My "listening room" is 16 x 24 x 12, with a large opening on one long side to another room. However, I don't play my music at ear-shattering levels, so there's no clipping on near-instantaneous changes in volume. The BP-26 has gone to live with my son, so the 17 cubed is the preamp.
No on yet has convinced me streaming is the way to go, so the classical CD collection is getting a workout.
