The Integra Research RDA-7.1 is a dynamic, low noise, cool-running, audiophile-sounding amplifier that exceeds its power ratings.   It can compete with many of today's best multi-channel designs regardless of price.  The THX Ultra2 certification is an added bonus which ensures system compatibility with other THX products, and has the stamp of approval that it satisfies their performance criteria, though I am very certain it exceeds them by a comfortable margin.

The downside is this amplifier is enormous and will have issues fitting in most standard racks or home entertainment centers.   I am uncertain why Integra Research didn't locate the dual power transformers on the bottom of the amp just under the heatsink modules.  This would have shaved at least four inches off the depth at the penalty of adding more height which is usually not the limiting factor for shelf space.

Careful planning must be facilitated if you plan integrating this amplifier into your home theater system.  The sound quality is among the best I have heard, as is the build quality, fit and finish.  The RDA-7.1 will likely satisfy any audiophile and home theater enthusiast alike.  The hard part will be convincing your significant other of the necessity of this monstrous amp in your home theater system.  It doesn't come cheap, but as a dear friend once told me "it's never cheap to be cool".  This amp certainly has a cool factor to it and in this instance I am in full agreement.  Finding a product that outshines its specifications by a wide margin is rare.  The question remains does this occur as often as a Solar Eclipse?  I think not.
