The 'Mrs' factor
For me, tis the 'Mrs' factor. Started off years ago with Mordant Short Genie 5.1, which went down like a lead balloon (huge sub), as did the migration to a pair of B&W 685's on stands. Moved into a new build house, and it was clear the Mrs was going with a minimalist theme (well, in comparison to what we squeezed into the living room previously), and I didn't even attempt to raise the question of speakers. So I managed to talk her into the DM75 to cover both music, and to raise the audio quality of a Sony 55" W8.
Sits under the TV and is hardly noticeable, sounds amazing, and once you've spent 5 mins training the Sony remote, springs to life whenever you take the TV out of standby.
Wife happy, and the audiophile wannabe in me smiles. Win. Especially as the 685's are now in the study, and the Genie's will be installed in the garage come spring. Everyone needs 5.1 in the garage don't they?
