TWO NEW TECHNOLOGIES THAT ARE CHANGING AUDIO  Since the 1960s a stereo was put together more or less like this:
This idea has brought us listening pleasure for generations. It does a beautiful job right up to the moment you ask it to reproduce HD Audio. Now the limitations built in to last century’s technology hold it back. The first problem arises from the “out-of-sight, out-of-mind” passive crossover circuits hidden inside your speakers that are necessary to divide the signal, sending bass to the woofer, midrange to the midrange and treble to the tweeter. You don’t need to be able to read this schematic to see that there’s a problem:
All you need to know is that that is a complex resonant circuit that works by storing energy and releasing it later. The mechanical analog would be: springs. It also resists the flow of current. The darn thing smears the signal and decouples the amplifier from the drivers; without all of those parts in the way, the amp would have a firm “grip” on the movement of the cones and domes. With them in the signal path, the amp’s control weakens, becoming soft and spongy. The net result of all of that is: you get distortion and detail is smeared and lost. I have designed hundreds of these circuits and can firmly attest: they were a necessary evil. There really is nothing good about them, but we could not do without them. Until now. Now, thanks to the latest technologies, we can do this:
Notice the three amplifiers? Once an amp had to be a large, heavy and expensive thing. No more; the fabulous new Class D amplifier modules have these three qualities: they’re small, cool running and excellent sounding. So excellent, in fact, that makers of large, heavy and expensive reference grade amplifiers are now using them in place of their earlier proprietary circuits - because they’re that much better. And we can perfectly mate them to their designated drivers, connected only by a short hunk of wire. NOTHING sounds as good as a first-rate amp connected directly to it’s driver. THAT is how you get resolution!
Now, the function once performed by that messy old crossover circuit gets moved ahead of amplification to render the single most elegant solution to an engineering problem that I have ever seen. We do that work on the datastream while it’s still 1s and 0s - so there are no losses, no degradation. Thanks to advances in processing power, Digital Signal Processors for audio are here now and they are fabulous. Plus we now have a whole new level of control, above-and-beyond what could be done with the circuits, that brings a whole new set of strategies for tackling the new demands for higher DR and higher resolution. And room correction comes along for the ride. We can now match pretty much any speaker to any environment.
All of this technology fits comfortably inside our speakers, so your modern stereo look like this:
