I need to make a comment here... We will not be able to accommodate double-wides in the same chassis with the normal or stereo blades. Initially we thought this would be possible, but extensive testing has forced us to make some changes. We needed to modify the rail voltages and the current capability of the SMPS in order to achieve the desired performance and durability needed for the double-wides. What this means is that you are limited to 1, 2, or 3 double wides in the XPA G3 chassis. You can't mix them with the other modules. A special super-duper power supply module will be fitted to these models. All other cosmetics are identical in appearance, as it is the same casing as the regular G3 XPA's. If you already own a G3 XPA-2 or 3 and you want to change out the blades to make it into a 2 or 3 channel double-wide, we'll swap out the SMPS too as a courtesy. Let the firestorm begin.... It's beginning to sound like I need me a 2 channel G3 with 2 double wides at 500-600 WPC with a special super duper power supply module (SSDPS  ) to replace my monoblocks. I'm ready. Please take my money! |

I hate to ask a dumb question. But it would be really neat to have a standard chassis whereby an end user can add and subtract different amplifier modules themselves, as well as add and subtract power supply modules. I'm sure it would be too expensive and troublesome for this to work. Regardless, since Emotiva is swapping supplies and doing this anyway, no biggie. |

I was a little excited when I learned that Emotiva does some brief burn in and Audio Precision checks as part of installing new modules... so it's more than just plug and play. I do still like the concept of end user installation/removal of stuff.... but I understand there are lots of other factors. (emphasized for the sight impaired) |

Sorry, Jim, but I see the EMO point. YOU might be capable and safe. Would some other guy? NOPE. And don't forget the amp stores energy at a fairly brisk DC voltage in the PS. OUCH!
Than you have Warranty issues. Guy installs while power is ON. You KNOW that's gonna happen. Wrong pins make contact first and ZAP. Now, what did you say about that Warranty?
A stereo PAIR of the doublewides would be terrific to biamp very low sensitivity speakers like my Maggies. Will that work on a SINGLE 15 amp service?

A special super-duper power supply module will be fitted to these models. Hi Dan, Will the "special super-duper power supply module" eventually become standard across all Gen 3 XPA's, even those not sold with the double wide blades? Thanks |

It could be designed to protect against those things. But I'm sure it would be too expensive for the target market. |

We've been down this road before. Please don't rehash it. I'm entitled to have a preference. Besides, a Darwin award here and there isn't all bad.  |

I'll drop it after ONE point. Product Liability: 'Nuff Said:
And sure, nobody wants to take your preference away. Just kind of show WHY a company might do something in a certain way.

Probably not. For optimum efficiency, a fully differential amplifier, which is essentially a pair of bridged amplifiers, wants to be run with a different supply rail voltage than a single amplifier does. Therefore, while a power supply can be designed to be optimum for one or the other, a single power supply can't be optimal for both. (In other words, if we used the super-duper monoblock power supply with the single modules, it would actually reduce their power output a bit.) A special super-duper power supply module will be fitted to these models. Hi Dan, Will the "special super-duper power supply module" eventually become standard across all Gen 3 XPA's, even those not sold with the double wide blades? Thanks |

You know, Jim, I'D like to see accessible / rear panel FUSE HOLDERS for at least the mains, if not the Rail PS, too. I don't get Any support for that one, either. Maybe more product liability? Here's a link to 6 different modules for NAD product. These are ALL low power, so nobody is getting Zapped. But YOU ARE RIGHT. It CAN be done. And it apparently works for NAD. nadelectronics.com/products/mdc-modulesOh! Well! |

Will there be a version that has three of the double wides in a single Gen 3 XPA chassis?
The CES 2017 topic shows a single double wide in a Gen 3 chassis but leaves one wondering
if there will also be two and three channel versions?
My hope is there will be a XPA-3D model. I'd like to power my LCR channels fully differential
and with the extra head room. I do have three dedicated 20 Amp branch circuits, so I won't
be starving them. The XPA-3D would have its own dedicated 120 Volt 20 Amp branch.
I just bought two Gen 3 XPA-7's around Thanksgiving and would like to add a XPA-3D if and
when available. At that time, I was tempted to buy three Gen 3 XPA-5's instead, with the plan
of sending them in to have a double wide blade added to each. I know now that that plan
would not have worked.
I'm hoping to firm up my plans while still within the return window of the two XPA-7's. My
new alternative plan is to have each of the XPA-7's taking care of their respective side of the
room. Then introduce a XPA-3D for the LCR, when available. Please let me know if I'm
headed in an impossible direction.
Thanks!

You cannot mix double wide and non-double wide blades in a single chassis. The dw requires a different power supply. You can have 1-3 double wide blades in a single chassis. |

Thanks for the reply dwaleke. Good news. My appologies. I should have read Dan's post above again.
He clearly states that the intent is to offer one, two and three channel configurations.
Exciting stuff. I intend to be an early purchaser of the three channel double-wide when they become
available. Sounds like perhaps February or March.
Those two channel single wide blades are cool too. I can see folks buying a mix of single and dual
channel single wide blades to give them a theater in a box. Awesome to be able to have three of
the single channel, single wide blades for the LCR channels and then fill out the chassis with the
double channel, single wides for another eight channels, 11 channels total. Lots of interesting combos.
Cheers

I don't know if I read that right but we're you talking about dual channel single wide modules and 11 channels in one chassis?
With the current single channel, single wide modules there is a maximum of 7 channels. And with the new double wide channels there will be a maximum of 3 channels allowed per chassis, with no other modules inside. The power supply for these will be different as far as I can tell and won't be able to be mixed with the other single wide channels. Also, I've never heard of a dual channel single wide blade.

And I'm a little fuzzy on the power supply swap, what exactly is being swapped and why? Also still want to know pricing 😁
