My new McIntosh MX-132 has a THX Cinema mode built into it.
Well, if one sets the pink noise in all 5 channels to 75 db at the listening location, which I have done, and then selects THX Cinema mode, the MX-132 also has a feature where, once the volume is advanced to a certain point, a light comes on the front panel indicating "THX Reference Level".
Well, last night I enjoyed all 3 hours of "Tora Tora Tora", one of my only DVDs with THX optimization, in THX mode with the volume set for THX Reference Level. Wow, what an amazing aural experience. Thundering bass and explosions. When the Zeros were launching from the deck of the Akagi, I was getting peaks of 112-113 db C weighted at my listening location. It uses a lot of amplification power, even with 102 db efficient speakers. Luckily, I've got 900 total watts of continuous, 20-20khz power available for the 5 channels, and my speakers can safely handle peaks of 1000 watts, so the only limiting factor to enjoying movies like this is my ears!!
