Aside from the rated power output, and the XLR connection sites, are there any other differences really between these amps for a 2 Channel Setup. I ask because I am going to be choosing between buying a 4ohm and and 8ohm set of speakers. And since I can technically get the same power with 4 ohms (300wpc) with the BasX vs 8 ohms (300wpc) with the XPA Gen 3, I was thinking of going with the 4ohm speakers and saving some money on the Amp, unless someone can give me a good reason the XPA is superior. I am sure there is something to it that I overlooked or probably just dont understand and Id love any of your input.
Thanks

Should I move this to the stupid question zone?

You could also try buying a used XPA-2 gen 1 or 2 for cheaper. |

Choose the better speakers - the amp will be much much less a factor.

Power is but one measure. The BasX is 1% distortion @ 4ohm rated power. No further information about, say, what the power is at 0.1% distortion @4ohms. |

I hate it when discussions like this get down to intangibles  Yes, the XPA Gen3 has lots more features... It also has a more sophisticated circuit design... So, if you were to look at all the test results, you would find that the XPA Gen3 rates better on several of them.... The XPA Gen3 is also going to sound a little bit cleaner, and be able to play louder without sounding strained... So, if you're looking for no-compromise performance, and the absolute best sound quality, then the XPA Gen3 is going to have an edge. But, in the end, a lot of it does come down to what you need. If you're on a budget, and especially if you don't listen to your music really loud, or have really hard to drive speakers, the BASX will get you 75% of the way there... for a fraction of the cost. And, if you ARE on a budget, especially at the low end of the price spectrum, spending more on speakers will probably buy you a bigger gain in sound quality. (And, on that note, don't forget to check out our new Airmotiv passive speakers.... they work really well with a BASX amp and sound really good.  ) |

Agree overall with Keith. One factor to ALSO consider when looking at amp / speaker combos is speaker sensitivity. 3db greater sensitivity is like purchasing double the amp power. 75 watts per speaker into some of the real old-school BIG BOX speakers, like Kllpsch or Bozak or Altec will get you evicted from the STATE you live in.
I don't know the sensitivity of the Airmotiv or absolute numbers of any other measure, but for a den system? Small LR? You'd be hard put to go far off the path with that kind of setup.
Getting better speakers for a given budget is just another reason I generally recommend STEREO rather than HT for those getting started and who also have an interest in better sound

Comparing the upa-200 to the SA-250 I get 80% of the of the performance from the upa-200. Now don't get me wrong I love the SA-250 but if I had not compared the two the Upa would make most music lovers very happyđ |

For those who WORK for a living it is ALWAYS about the balance of Bang / Buck / Needs. Some guys will Thrive on the '80% solution' while others will not be happy unless they go Pot Limit.
My neighbor is a Bicycle Nut. He owns a fairly expensive (like around 1500$) bike which is nearly meaningless to me. I'm perfectly happy at a fraction that level. But my stereo? He thinks I'M nuts having gone well past the HTIB level and into the unfathomable world of Components. Crazy.

My only Emo amp, a 50 Wpc a-100 mini-X, is an example in a minimalist approach. It is connected to a pair of large bookshelf speakers - Klipsch RB-81ii's, front ported BR with an 8" LF driver & Ti horn, reportedly with a SPL of 97 dB. They are very sensitive - easily driven - and produce painful, but clean, sound levels in my 11' x 12' office. I would buy the best speakers I could afford - and power it with a BasX amp and not worry - that high-ish rated THD level is at the max power - probably <.05% at reasonable power levels - it is an Emotiva amp!

Think in systems. What do you really want once it is done? Speaker choice, Room Considerations, Your Budget overall. Ability to Scale the system if need be. Your involvement in said system. Music, and Theater. I have to agree the speakers are the voice of the system. The Amplifier gives the speaker the authority, and clarity in the voice. Matching, and getting the intangibles solved beyond numbers, and everything else is the harder, but not impossible part. Impedance, efficiency, costs, your personal taste are in the recipe for your final system.
I agree the simpler the better. Weigh the features as realized must haves, vs. nice to have. Such as XLR Balanced, do you really want/need to have in your system. Is the Purpose of Use of that feature aiding you in achieving your goal. Power, Form Factor, again costs. There are allot of considerations, but if you are patient, and get it all together in your ideal, it will entertain you for years ahead. Want to really scare yourself good in a great solution? A pair of Stealth 8 speakers. All the considerations were managed for you. You provide source, Subwoofer to taste, and Preamplifier control. Just one idea.

I would love to see some reviews on the new GEN 3 amps, why is the mistery about this new line of products, EMO retired the specs from the web for some errors, I don´t know but Big Dan most explain what´s going on with it, and definitely facilitate equipment to reviewers. Reviews are very important fo those who can not auditioning the equipment prior to buy.
Happy listening

I finally got around to set up my new XPA-2 Gen-3 last night. I have it connected to an XDA-2 Gen-2, and powering a set of Mirage OMD-28 f/s speakers without a Subwoofer.
I have it connected to a Gen-2 XDA-2, and I streamed music from Tidal via Sonos connect, and also played CD's via my Onkyo CDP 7030.
My first impressions are extremely favorable, the sound is really delicate, powerful and the highs are not very bright but very clear, mid's very detailed, and the low ends were very present and integrated, not boomy at all. I am not an audiophile, but I have owned and listened to many stereo equipment and I definitely love the sound and the dynamics of this amp. It handled every genre of music I tried, and never struggled at really high levels,..I had to turn the volume down as my ears were hurting. At low levels, the sound was still very clear and detailed.
I used to use an XPA-2 Gen2 in the same set up, and I find the new Gen-3 to have more " detail and strength may be?, but definitely all the power you may need to run the most difficult to drive speakers.
I was a bit worried this maybe a set back, but the Class D amp really delivers, and it can go super loud w/o any distortion, I love the half weight compared to the XPA-2 Gen-2, and the amplifier never got hot after few hours of playing at somewhat loud levels ( waited to have the house for myself for few hours).
I would definitely recommend this amp. In fact it will stay with me for a long, long time and i won't think of replacing it at all. If u r hesitant, u should take the plunge and see/hear for yourself. I hope this helps.

some objective person who can help me analyze my next purchase, my choices are narrowed down to two PARASOUND NEW CLASSIC 2250 V.2 or EMO XPA 2 - GEN3., both look very similar in the numbers and price (EMO $899, PARASOUND now on sale $999),, eventhough different technologies, but I´ve been unable to find reveviews on the GEN 3 so far. Here you´ll find the specs for the parasound: PARASOUND SPECS.pdf (243.93 KB) |

There's no "mystery"..... We take lots of measurements, under a lot of different test conditions.... and then, somewhere along the line, we print out some "pretty" test reports and publish them. We didn't "retire the specs" ... we just took down a few saved test report printouts. As for "professional reviews"..... to a point we "offer" units to reviewers, but most of them ask for units when they want to review them.... So, suggest to your favorite magazine reviewer that they review our amps, and have them give us a call.... I would love to see some reviews on the new GEN 3 amps, why is the mistery about this new line of products, EMO retired the specs from the web for some errors, I don´t know but Big Dan most explain what´s going on with it, and definitely facilitate equipment to reviewers.

Agreed..... but, to avoid any confusion, Class H is NOT digital..... it's just a Class A/B amp with multiple power supply rails. The only part of the Gen3 that could reasonably be called "digital" is the power supply itself (it is a SMPS, which isn't exactly digital, but it's a switcher). (So, strictly speaking, at most it's an ANALOG CLASS A/B amplifier with a digital power supply.) The Gen3 is not Class D. Just a point of clarity. You're right, Class H. However, to me, digital is digital!!! |
