My personal opinion is that the switching power supply will not be equal to the task that the previous transformers were. If you look at the new specs the power rating falls as channels are added. The same amp module rated at 300 wpc output provides full rated power with two channels, but drops to only 200 wpc output with seven modules installed. Since the amp modules are rated the same, they are in fact limited to less power output only because of the switching power supply. I will stick with my Gen 1 and Gen 2 amps until something proven to be better comes along. No knocking it just stating the facts. Also, there seems to be 10% higher THD with the new Gen 3 amps. Food for thought...

Food for thought... Tim perhaps the 7 channel model should have two power supplies? There's space inside. As for power/THD mine are Total Harmonic Distortion (THD) Less than 0.03% at full rated FTC power |

Look at the competition, compare real value for the dollar, and I believe you are going to see that we are staying true to our principles. The disconnect in here is you are comparing yourself against your competitors (and no doubt come out favorably), whereas everyone else here is comparing you against your prior self. |

If 200 watts per channel at 8 ohms 0.1% thd isn't MORE than adequately powering a 8 ohm, 89 decibel @ 1 watt at 1 meter-effecient speaker with power to spare, then there must be a defect with either the amp or speaker. I would contact the manufacturer. Right. As if the Revels are some exotic load on an amp. The XPA-5 drives far more difficult speakers than those without breaking a sweat. The XPR's may sound slightly different with them, though, since they have different amplifier technology, but the difference would be subtle at best. |

I still can't help but think "where's the beef". I get the idea behind class g/h amplifiers but can't get the idea of a Toyota Prius out of my head. At least that's what it reminds me of. Hybrid car using a small low power electric motor to get running and kicking over to combustion for power. That's probably a stretch but you can probably see how someone draws a line between the two ideas.
I kinda get a kick out of having buddies try to lift the front of my XPR-2. They about crap when they feel the 72 lbs of resistance. I personally don't care how efficient the amp is as long as it continues to drive my speakers at the volumes I play my music at. My speakers easily hit 4 ohms. As long as my amp keeps us (XPR-2 gen 2 always has) then I'm pleased.

Sorry, I couldn't resist. |

Everyones all up in arms like Chicken Little, speculating about the new products and reviewing/criticizing them before they've even heard anything. For goodness sake, why not wait until you've heard them before making judgements, eh?  |

I believe their A/B and G if that's possible. Both of those amps can easily keep up with my XPR-2 at half the weight. The US production is also a great thing. |

Because these are the interwebs forums and folks really do just like to complain just to hear themselves type. lol But I think a lot has to do to with the old school thinking of heavier is better without really understanding the engineering behind it. When a positive "pro" review comes out then folks will come around. Humm....maybe a lead encased t-amp will sell well after all.  |

But I like those 8.5 lb Crown Class D amps I bought a few months ago. I think the changes in technology Emo is implementing need to prove themselves but I also think they need to be given the chance to prove themselves rather than being judged before the gate's even been opened. |

Keep the faith, we are interested in servicing all of our customers at all price points with high value, great sounding products... Except for the Rolls Royce crowd, that's not us. Although they may find they don't need to spend $10k for a nice amp if they give us a listen. I've been paying attention to this discussion for the last couple of days now and this is what I've come up with. Emotiva is giving up it's reference (Rolls Royce) line and the XPA series will be their top line. The XPA line is getting reference line technology incorporated into them. There will be a Base X line of affordable but great performing amplifiers coming. So from what I can figure, Emotiva is going from a three line "line up" to a two line "line up". The top of the two lines will be the XPA line. These will have "near" reference level sound without the "no holds barred" accouterments. While the Base X line will have the Classic X line sound, without the "overbuilt" chassis and the "extra" punch. I'm just trying to read between the lines here and figure things out. Ah-ha, but perhaps you missed some info. They have not yet announced their full line up of new equipment. Twenty-six new products of which only 16 have been announced. Dan has stated very recently that we will all know the full new line up by summer and we will "crap our pants" in excitement. It's a waste of time to speculate in this situation. Anticipation.................. |

Call me crazy but the Crown xls are the benchmark for my assessment on all other amps. They give you so much for such little cost and weight. |

Both of those amps can easily keep up with my XPR-2 at half the weight. The US production is also a great thing. The old Caver amps are Class G with the power supply. Some of the audio signal path is like what you find in Class A/B. The TFM series were designed for speakers that were considered a difficult load. |

I don't understand the gear-fetishist "audiophile's" obsession with antiquated technology. This is a step in the right direction for Emotiva. I can't really think of a good reason not to transition completely to class D amps actually. Lighter and much more efficient technology with no audible difference in sound. |

And,,,,,I really hate to bring this up,,,,,!! But, it needs to be asked.
How much will an eventual upgrade power module cost?

Like mega-buck esoteric audio cables, mega-heavy amps offer little more than bragging rights. However....... When it comes to linear power supplies, heavier typically means more capable. |

There will be a Base X line of affordable but great performing amplifiers coming. You forgot about the Emersa line, so far there appears to be three lines. Your right, I did forget about the Emersa line. I think that is because, as it has been presented, I'm not interested in it. The Emersa line is for a different lifestyle. Great sounding equipment for the discerning consumer, not the obsessive audiophile (me). From what I understand it contains integrated components, which I understand some here are interested in, but I'm not. Though like DavidR said. They're still ten new products that have yet to be announced. We'll see which falls where. |

It's all measurements and numbers and graphs. Right? |

How much will an eventual upgrade power module cost? Hey Nick, here's a post by Dan from a couple days ago that should answer your question. Remember, 300 watt blades only cost $200.00. It'll be a very nominal fee for additions and shipping if you decide to re-configure. Also, your amplifier will be completely run through testing and burn-in when it is sent in for modifications. Nice. We are very concerned about others doing this, even though it seems simple, because of the very high internal voltages present and the need to properly QC the amplifiers after changes have been made. Cheers, Big Dan |
