Re: For those who don't believe in room correction...

I used to think as you do but now I'm not so sure. I read a couple of articles on digital room correction and a few more on digital filters on Robert E Greene's site (TAS reviewer) and it appears that digital filters can compensate for early reflections by delaying the filter's action in time.

I have no personal experience of such devices but I have gone from saying it couldn't be done and one had to treat the room to wondering whether it can be done and, if so, how well. One thing, though, is that it appears that the digital correction may not hold up as well as you move away from the sweet spot where the measurements were taken as physical treatments do, so good listening may be restricted to a smaller area than it is with phsical treatments. At this stage I'm also enough of a throwback to want to stick with acoustic room treatments but I wish I could make them more attractive than my DIY versions.

So there may actually be a new way to skin this particular cat. Still, there ain't no free lunch with room treatments and I suspect there's prices to pay with digital room correction as well. It will eventually come down to what each does best, what each does worst, and which one gives you as much as possible of what you want while avoiding or minimising what you don't want, and some people will have preferences which aren't based on sound so much as philosophy (keeping the electronics as simple as possible and staying with physical treatments) or convenience/aesthetics and going with digital.
