No one, and we mean no one, has been doing room correction longer or better than TacT. But unlike a lot of other manufacturers of high-end surround preamp-processors, TacT has been quick to adopt HDMI 1.3, so the new TCS pre-pro can handle Dolby TrueHD, DTS-HD, etc. Each of 12 channels may be configured as a main or sub channel. The ICS (Internet Correction Services) feature will let you upload your settings to the web where they may be analyzed or stored. The before-and-after demo revealed a better focused (but not as warm) sound in the after part. The product will ship in February for 15 grand.
