For the 40 inch in an office, may check out the YSP800. Little smaller, and will probably work better for a 40 inch in an office.
The main use for us of the YSP is for applications were either the looks are a factor, (wife does not want anything AV let alone 5 speakers.) Or in applications were cost overruns make traditional 5.1 systems not an option.
Like retro work in appartments, condos, and that type of install. The customer will be more happy spending the money on the YSP1100 vs, sheet rock repair, paint repair, and the AV install charges.
I have only compaired the YSP to the Bose 3,2,1 system. I like the YSP sound better. Throw in a sub with the YSP and you will be very happy.
