EDIT: Isone Pro has been upgraded to TB Isone, and the new link is here: http://www.toneboosters.com/tb-isone/ --------------------------------------------------------------------------- I just want to share my latest discovery with my fellow head-fiers. I have always disliked the "in your head" sound of headphones when compared to speakers, and while I have tried some of the crossfeed DSP processing plugins (both free and commercial ones), none have ever actually impressed me. That is, until I tried Isone Pro. I was completely blown away by how it was able to make my headphones sound just like speakers--the effect was so realistic that I thought I had left my K+H O300D's on, and it was 1 am in the morning, so I was afraid I'd have woken up the neighbors. That is how convincing it was. It even does surround sound! I have tried Redline Monitor, hdphx, the headphone crossfeed feature that comes with J River Media Center 14, and some of the ones for Winamp--none of them have ever sounded as realistic as Isone Pro--not even close. Best $27 I've ever spent for my headphones. I highly recommend that you download the demo version and see for yourself how amazing it is: http://www.toneboosters.com/tb-isone/ (TB Isone can be made to sound identical to Isone Pro, so there's no need to try and find Isone Pro anymore--just use TB Isone.) Here's a discussion thread comparing it to Redline Monitor: KVR: Redline Monitor or Isone Pro? (EDIT: There's now another HRTF product called Ircam HEar: http://www.fluxhome.com/products/plug_ins/ircam_hear Its realism is comparable to Isone I think, but it doesn't have all those controls and presets that emulate different environments and speakers, and it costs more as well. You can download the trial version and see how you like it. I see no reason to get it over Isone since it has less features and costs more. Maybe the people that don't want to fiddle with the controls of Isone might like how simple HEar is.) For those of you who don't have a media librarian/player that can use VST plugins, I highly recommend you try J River Media Center. It has VST hosting, and not just one, but a full chain of as many as your computer can handle. That means you can host very high-end professional spectrum analyzers, EQ's, Mastering compressors, and whatever else you want. Winamp now also has a plug-in that can host VST's. Media Monkey with some customizing can also do it, since MM is compatible with Winamp. Supposedly you can host more than one VST in MM if you do some tweaking. Personally, J River Media Center 14 is just less of a headache IMO. It kicks the crap out of all the media librarians/players I've ever tried, and I think I pretty much tried them all in the last several years--from foobar to whatever flavor of the month.
