Just curious, but were these designs completely fresh from Andrew Welker, or is at least a little of Tom Cumberland's work on the A1400-8 and A1400-2 informing the design of these new amp series?

CV, I doubt there's anything left of Tom Cumberland's designs in the new amplifier series. But Andrew is better qualified to answer that.

Cheers,
Alan

In the interest of cost-savings, would it be feasible to buy a 3-channel model for FL,C,FR and let my receiver drive the surrounds? Or would this result in a channel volume level mismatch at high volumes where the receiver's power ratings can't keep up with the Axiom?

Henry, the way I read Ian's chart is that Axiom will configure each amp with anywhere from 2 to 8 channels based on consumer preference. I don't think there would be any problem doing what you envision; your receiver would be able to adjust the levels accordingly.

From a basic technology standpoint, the building blocks of the amplifiers (Class D amplifiers strapped to a high current linear power supply) remain true to the earlier design. However, all of the individual elements are ground up designs, and this includes the way the amplifiers are assembled. Technology races on and there are new and far more sophisticated devices available today that were unheard of 6 years ago, and these are incorporated into all of the new amplifiers.

Henry66,

This is a really good idea. Not only do you end up with some real power where you need it across all the front channels, you will now be designating the entire power supply of your receiver to the surround channels. This will give them added power also since almost always the limiting factor in a receiver is not the power per channel but the overall power available as determined by the power supply.

Henry, many people do what your asking, should not be a problem as long as you calibrate all the speakers initially via SPL meter or other setup routine.

Does this design reroute unused power to the other channels needing the power, like Tom's design, that was a nice feature?

Thanks for the response, Andrew. Maybe you can go into further detail as the release approaches?

And I was wondering the same thing, Randy.

CV and Randy,

Yes it does work the same in that way.

It's great to see these questions answered on the forum!

I have another:

JP, can I borrow $2.000 and have a REALLY flexible payback plan?
