Honestly, I would prefer to have an all in one powered speaker - speaker/amp/dac. The reason for me is simple - it's not my main audio system (I already have one in a separate room), and it's not my home theatre system (have one of those, too). I want something that's good, but not where I am needing to buy all these components and turning it into a miniature version of the two systems I already have. Just something that I can enjoy music and movies from when I am in my office all day working.
The KEF is an all in one. The A5+s would need a DAC, and the Schist Modi 2 is cheap and good (especially for this specific set-up). So that's about as much gear as I would want to buy for a casual, while working set-up. I don't want to have to dig into passive speakers, amp, pre and dac - it's way overkill for something that is NOT a primary system.
