Too many active speaker systems still rely on external 'boxes' to make a complete system. (Pre-amps or DAC/pre-amps + sources both traditional and otherwise, wireless and wired.)
This can make a nonsense of the biggest perceived benefit of active speakers (compactness, neatness, reduction of cables and clutter). Even AVI have gone back to making a 'bare bones' active speaker without any such built-in functionality (ADM5s) which was a bit bizarre given how cool a smaller, cheaper version of the ADM9s might have been.
A pre-amp usually costs more than an integrated amp (from the same company) because it will come from higher up the manufacturer's range. Good DAC pre-amps (with some analogue provision, a volume control and a remote) are also, typically, quite expensive.
The way forward has already proved to be active systems that are competely integrated, whether it's a B&W A7 or Sonos Play / Cambridge Audio Minx type of device or B&O and Meridian and Linn active systems at the other end of the budget scale.
There are others filling in the gaps between (Quad 9AS, Dynaudio Xeo, KEF 300a as a few 'for instances').
Pro shops don't really get much foot traffic from the domestic market (with it's insistence on kit that doesn't look like a refugee from a teenager's bedroom 'studio').
It is not the active nature of some of this 'new wave' equipment (for want of a better term) that sells it. Indeed a lot of these integrated systems are passive 'powered' devices. It is their completely integrated nature, compactness, good design and domestic compatibility that sells them. A tiny percentage of customers will care whether axctive technology was responsible for them sounding good.
The market (and not education) will determine what succeeds. B&W are succeeding with their A7, A5, Zeps and Z series systems in spite of the technology within and not because of it. No-one cares.
Ruark's success (with their mini systems and radios) is because they sound good, look good and they were well marketed in lifestyle mags and national newspapers and because they sell in the sort of places (and websites) that people actually go shopping in (and not predominately male oriented, pokey little hi-fi garrets in the lowest rent area of town, but places like John Lewis branches for example). Whether they are active or passive is, again, meaningless.
Even I would want to run away from some goon trying to evangalise active vs passive to me (and I understand the difference). No-one needs that c##p on a Saturday morning. Show me what's within my budget, tell me if it'll work with my other stuff (TV, iPhone, iPad, laptop or whatever) and let me listen. If my wife hasn't thown up on the shop floor at the sight of it, threatened divorce at the price of it (and it sounds good) then i'll have some of it please. That's how it works.
