They're way too expensive for me. Yet.
Several companies, such as TacT, SigTech, and Perpetual Technologies, are offering products that can digitally equalize your speakers to counteract problems in your listening room. Is this of interest to you?
What's the status of dolby headphones? Where do they fall (compared to speakers.) Wouldn't the extra processing involved hamper dither? What about the different HRTF functions required? If they make a "[general/universal]" hrtf rating, doesn't that mean they'll be cutting corners too?
Of course! The room interface is the most important aspect of satisfying high-end sound. Most components now acheive a reasonable level of clarity, get the tonality basically right etc.. but only a properly set-up stereo can acheive the soundstaging that define the truely high end system. If digital room correction can help acheive that, then it will be worth every penny.
My listening space is in my attic. It has a very complex roof configuration and wall outline, as well as a staircase. It is great for combatting standing waves but defies conventional acoustic analysis. If digital equalization can tell me how to improve the sound, and I mean improve, not just change, I am interested.
If these products can allow me to avoid having to use absorption devices,etc.,which my wife doesn't want to have hanging on the walls and taking up space in the corners then I would have a definate interest.I've just moved ino a house that has high ceilings in the listening room and there are room problems that need to be corrected.
