Wow...you guys are killin' me. ;D I need to update this when I get some spare time. I will take heed of your suggestions/corrections at that time.
When will then be now...soon.

Hey Doug,
Thanks for being the guardian of this information. I noticed a couple of...anomalies...in the charts. First, on the old generation page, there is no listing for gain structure. Second, on the new generation page, there are two. Seems like the new generation amps need a lesson in sharing ;D.
No biggie, but I thought I'd point it out. There are some that scrutinize everything ever "published" about an piece of equipment with an electron microscope.

Dann/Lonnie: (Apology in advance if this info was posted somewhere earlier) Can you guys please post the following info for the XPA-2 thru 5 amps... 1. Crosstalk numbers. 2. Voltage gain (is it the same 32db for both the RCA and XLR connectors?) Thanks. I would love to see S/N specs for the balanced & unbalanced outputs, if they are different. |

The specs have changed once again. Now the 4 ohm power outputs for XPA-5 and XPA-3 are listed as 300W and not 350W. I wonder if anything changed in the newer versions of the amps.
Cheers

I also noticed the XPA-3 test PDF shows 5 channels and there are no longer power ratings for 1 and 2 channels for the xpa-3. Forthcoming perhaps?

Hey, just bought a pair of RS8's. I am running them off a old yamaha receiver RX-V595. The "dynamic power" is 120Wpc for a 6 ohm speaker, but I wonder what I am really getting? I am thinking of adding a Emotiva UPA-2. What do you guys think? Any other thoughts on making this a good 2 channel system for music only...?

Cheers Hmmmm i'd like to know what's up with that as well? Did they make some change's that forced them to lower the rating's like maybe lesser quality cap's or something? If so i hope i got an older model! When i ordered my unit a couple week's ago i'm pretty shure they were rated @ 350w/ch @ 4ohm  I thought i read earlier somewhere that an independant review/test was done on the xpa5 and it was actually putting out more than the rated 200w/ch @ 8ohm's it was more something like 210w/ch all channel's driven  |

You probably wouldnt even notice a difference between 300 and 350 watts, its basically inaudible. |

They handily exceed all of the printed specs. For example, they report THD at 0.1% when they actually measure at 0.007%. From a marketing point, the 0.1 looks bad, but you can not hear the difference at those levels anyway. They just choose to make sure they don't over report like many companies do. |

I am thinking of adding a Emotiva UPA-2. What do you guys think? Any other thoughts on making this a good 2 channel system for music only...? If they report power output in "dynamic" power...that number is far greater than the proper specs...which would be RMS, all channels driven between 20 hz and 20Khz with no more than such and such distortion. Dynamic power can mean anything they want it to mean. To me, it means it's not a very good amp. A UPA-2 would put out FAR more real power than that yamaha. |

Dynamic power can mean anything they want it to mean. To me, it means it's not a very good amp. A UPA-2 would put out FAR more real power than that yamaha. "Dynamic power" is like if you rest for a week then get up and run as fast as you can (downhill) and then leap as far as you can, and then someone measures how much energy you had. Then they carry you away on a stretcher so you can rest another week to do it again because you have no more energy left. The standard that Emo uses to measure things is more like what a well-trained person can do as a constant or steady output of energy in a marathon or triathalon, and keep on doing it. ;D |

Great Explanation!

Friends,
Hello from the islands of the Azores!
About the comparison chart, I see that the UPA-2 is lacking some information, is that for some special reason?

Being new, I don't know if this is the place to post it but I am in the process of comparing my brand new XPA-5 to my vintage McIntosh MC-275. The XPA-5 is not even broken in, but so far I woiuld have to say it is holding it's own. I'm using my McIntosh C22 preamp in both cases so I have a nice "tubed" sound in both instances.
