Someone that has a home cinema or multi room setup that is relevant to go for that much power, and that can dedicate two circuits for amplification power is very likely to have a dedicated electrical closet with a rack. Are there rack mounting option? Nobody need such an ugly beast in plain view and it doesn't belong in typical living room credenzas, It's not made for a living room.
I do not know why (house built in 1968 and is [at 1100 sq. ft.] the smallest house in the neighborhood) but my house has 20 amp outlets through out the house and the ones in the living room are on 2 separate circuits. Serendipity strikes here with my homes outlet and circuits being what they are (this is actually the first Class D that really has my attention as the power side of my system. I run a pair of main speakers and a pair of subs. With my pair of APT/Holman preamps I can have QUAD with QUAD subs with the Buckeye Hypex NC502MP 8-channel class D amplifier:
Quadraphonic Synthesis
With two Holman Preamplifiers, you can synthesis and control four output channels from just two input channels.
Apply all your inputs to the first Holman Preamplifier. Use it for all your tone controls, filters and source and tape selections. Leave its Stereo Mode in Stereo.
Connect the first Holman Preamplifier's MAIN 1 output to one power amplifier and your two front speakers.
Connect the first Holman Preamplifier's MAIN 2 output to any line-level input of the second Holman Preamplifier.
Connect the second Holman Preamplifier's MAIN 1 output to the power amplifier for your two rear speakers.
Rotate the second Holman Preamplifier's stereo mode control to L-R, and start by setting it to about unity gain or a bit less, and keep its tone controls flat. The tone and filter settings of the first Holman Preamplifier are fed automatically to the second Holman Preamplifier.
Set balance on the first preamp. Set front-rear balance on the Volume control of the second preamp.
Leave the power switch of the second preamp ON, and plug its power cord into a switched outlet of the first Holman Preamplifier. Now the power is controlled by the first Holman Preamplifier, too.
Not to mention what you can put into the processor loops using using ADC DAC EQ's, etc.
Finally a Class D to seriously consider for my application (and reduce boxes). I can actually formulate a plan for next year now (I already spent this years budgeted audio $'s)
