XPA-4 Gen 3 4 Ohm output

[metaldaze]

Does anyone know the output for the gen 3 amps at 4 ohms, all channels driven?

My configuration is with 4 mono blades.  

Thanks in advance

I've combed reviews online and came up with nothing. Currently I'm running 3 of the 5 channels in a Gen 3 5 Channel amp at 4ohms.

So there is no spec for it, but by doing some math I am thinking around 400WPC all channels driven at 4ohms is about right. I am just looking at the 5 channel specs and seeing the delta from 2 channels to 5 channels on 8 ohm and using that same delta from the published 4 ohm 2 channel specs. I may be off a tad, but it should be fairly close.

I'm driving 4 ohm Elac's with a XPA-5 Gen 3. The answer to your question is plenty.

I'm driving 4ohm Thiel CS1.6 with a 4ohm Thiel SCS3 center channel and there is plenty of power. The Thiels are rated 4ohm minimum. In reviews they actually dip to 3ohm.

I also came up with very little in  my search of those parameters.  A lot of what I found was "not a real world situation" which, okay it probably isn't for a large majority of the time. But it's one I'd still like to know since I can guess & calculate all I want. But don't have any idea on the distortion figures for the numbers I come up with. 

In my case I acquired speakers that can be properly bi-amped & withstand around 1,000 watts of input per channel. Deafening it would be, but I like to know what I'm working with to help establish limits. I always trust my ears but I like 'facts & figures'  as well.  The amp has 4 mono blades so I'd be using the whole power supply over the four channels, on a pair of speakers.

This is what I came up with too. I factored 60% efficiency on the advertised 3.2Kw switching power supply. Looking at the FTC numbers they give for 2 channels into 4 ohms it sounded in the ballpark. 450 is what I actually got but I figured 400 would be more realistic and without TONS of distortion.

I just purchased Emotiva's DR-3. No question as to the output as they advertise 600 watts rms all channels driven into 4 ohms

I saw your post in your other thread about the DR series. Do you really feel that the difference is that audible? Your speakers are sensitive and resolving so I would imagine if there was any setting where a difference would be noted, yours would be a prime example. 

I ask because I've been with my amp for almost 3 years and I feel like I'm ready for a change. I've been thinking about Parasound 2250V2 or something similar. The A21+ looks nice but at basically twice what my XPA-4 costed, thats not quite in my budget right now. 

I also need to call Emotiva I guess and see if there's any trade in/up program to try the DR amps. But all in all, owning a UPA-2 and UPA-1 I feel like I'm interested in a different sound signature overall. One that's a little warmer, hence the change of brand. 

(I'd love to hear a PS audio [higher bias class A] with still good power numbers- or Bryston amp but even second hand market is very expensive from what I've seen for a used amp) 

I've heard McIntosh in the showroom hooked up to (what the salesman said was a $100,000 system. B&W blah blah) & to my own surprise was much less than impressed than I thought I would be. So I guess 'house sound' really does play a role.

Sometimes wanting is more than having. I doubt if the same spec Para will outperform the Emo, and in most cases, the Emotiva amps outperformed even the newest Parasound stuff. I use an XPA-2 G2 connected to some power hungry Klipsch Palladiums towers, three 8" drivers, rated at 4 ohm, and drops below that. I don't need any more power than this 5 year old amp has, but the upgrade bug does hit me sometimes. A new DR-2, HC mono blocks, something else?

I agree to an extent. The distortion figures and power output into 8/4 is the same. What I've found influences the sound is the designers choice of components and where they are in relation to one another in the circuit. Couple this with a substantial increase in current availability per channel and lower IMD numbers, as well as much lower even and odd order harmonics.  Not to mention Class A for the first several watts. 

At lower listening levels there should be little difference in sound presentation. Where I find the differences become more pronounced is with higher listening levels (which Is where I'm at a good amount of time) and more difficult loads. With my 4 ohm speakers even the UPA-2 I have and compared against begins to wander into non-linearity (or so it sounds) as the volume is raised. 

The Gen 3 XPA holds its own pretty much independent of what it's powering. However, again only my experience with my ears, equipment and room. I find it very good in the bottom end. Good control and definition. However in the upper registers, although very clear and precise in the sound. Its a bit dry in the mid's and sometimes (Source dependent) less than delicate in the treble. My speakers and room interactions play a huge role in this. But even after room treatments which reveal more in terms of hearing deeper into the music, do nothing to change your speaker/amp interaction. 

All this refers to 2 channel listening. In home theater applications and gaming, its a no brainer. I didn't think when I set up my room I would be doing as much 2 channel as I am now. Don't get me wrong though, my recently acquired pre-amp has home theater bypass. Soon another amp will be taking over exclusive 2 channel duty, but the Emotiva amps aren't going anywhere. They will still be used for my center, surrounds and subwoofers on my bi-amp capable 2 channel speakers. 

They are still a VERY good value for the money, and even then I am comparing them to an amplifier twice the XPA's cost. That also says a lot. Though my search for the sound I'm after isn't over. I do not regret my investments with Emotiva
