Emotiva Amplifier

[joeh]

I am getting ready to purchase an Emotive Amplifier in the next two to three months.  I will be using an XMC-1 and my room is setup for a full 7.2 system.  I will be driving 7 speakers but I will be using only one sub to start with.  Emotiva allows custom builds for amplifiers but why would I want to spending $1,999 on a seven channel amplifier versus buying say a fourteen channel for the same price?  After all this would allow for future expansion if I decide to upgrade the processor to the RMC.

I think three 200 watt blades and four stereo blades is a good way to go. Surrounds and Atmos channels don't work that hard. You'd have eight channels with plenty of power to run your surrounds and overheads and three channels with serious grunt for the important LCR channels.

What kind of power are you looking for? At $2k? You found a 14 channel amp that will drive all 14 with the same power of Emotiva's 7?

I'll assume you are comparing the XPA-7 to the custom 14 channel. The XPA-7 delivers 200 wattsRMS/channel all channels driven. The custom 14 channel delivers 75wattsRMS/channel.
For custom builds first you need to understand the moduals/blades that are being used. There are 2, one is a 300wattRMS mono blade and the other is a 150watt 2 channel( 2x 75watt) stereo blade.
The XPA class amp case allows for a total of 7 blades, weather they be the mono or the stereo or a blend of both.
The reason for the 200watts/channel for the XPA-7 instead of 300watts(which the mono blades are rated ) is that they all run off the same power supply(PS). It starts at 300wats/chn with 2 channels down to 200 watts/chn at 7.
I think the stereo blade aren't effected the same way as the PS can power them all at 75 watts/ chn.

What you need to know next is the power req's for all the 7 speakers in your set up. Then you can calculate what you need / channel for your custom build.

I will be pushing a pair of T2's, two pairs of E2's, and one C1.

Then  go with what petew said, 3 mono blades and 4 stereo , that will leave you with 4 75watt channels if you decide to add more surrounds or atmos later.
