Apologize if this has already been asked before, but is the damping factor acurate in the document posted in this thread?

I need to get these caught up...if only there was about 30 hours in a day... if there were 30 hours in a day, trust me I would sleep the extra 6 be nice to see the other new amps too upa-1 at least

I have created a PDF for comparing the amplifiers Emotiva produces. You can find it here: Amplifier ComparisonI think the document is very accurate at this point, but Lonnie will be looking over it when he gets a chance to assure its accuracy. All diminsion measurements were taken by actual users of the products (myself included), so these numbers may disagree with the manuals/product page, but I feel are more true to life for those trying to fit gear in tight places. In your online document is shows the XPA-2 at 250 watts into 8 ohms but I show it is 300 watts RMS x 2 into 8 ohms, 500 watts RMS x 2 into 4 ohms. Not sure if it has changed or I am looking at this wrong?

The original specs for the XPA- 2 were 250 watts, but I think it was earlier this year they were revised upwards to 300 because Lonnie said that was a more accurate figure, and were within tolerance. Maybe that was to separate them more from the UPA-1's that were soon to be released at that time? Seeing as how I own one of them, I prefer the 300 watt figure. ;D

I kept wondering why the reviews and most documents I found did not match what was on the Emotiva website. I get it now. ;D

I'm still abit confused about the 250w vs 300w rating. The Audio Precision test report states ~265w @ 8ohm ?

Bit of repeated typo in the PDF: "dampening" instead of damping... Great info!

Quick question about the XPA-5. Web site/ Owners Manual 5x200 watts into 8 Ohms/ 250 watts into 8 Ohms 5x300 watts into 4 Ohms/ 440 watts into 4 Ohms Any idea why the differance? There are a few other differances, just wondering which is correct? I intend to get one next month.

Website specifies 20Hz to 20KHz while manual specifies @ 1KHz.

Manual for the X-Series shows that difference showing on Pg. 9 250W, and on Pg. 32 300W into 8 Ohms!! Come on EMO, sync 'em UP there.

Called PARASOUND at 1-415-397-7100, and asked some technical questions about their newly released latest Model 5250v2 a 5 Ch. Amp.
MSRP = $2850 USD OUCH!!
But it's rated at 250W RMS / Ch. ==> 8 Ohms ACD
Interesting, they have TWO (2) Toroid Xformers, and it weighs in at 69#, only 3# heavier than the EMO XPA-5, but produces 250 x 5 = 1250W, 25% More than EMO's XPA-5, but costs 317% MORE!! Ok, so you would get THX Ultra 2 Certification.
Parasounds techE... did not know the VA for each Xformer, but is to get back to me. Parasound recommended that a 20 Amp CCT. be used for this Model 5250v2! Also, only UnBalanced inputs to amp, but with Variable Gain knobs on back for each of the five Amps internally.
So, in essence it's 317% MORE $ than EMO, and only produces 25% MORE Power than an EMO XPA-5, that is if believe in both Mfg's. specs.!! That is a taxing situation, so what would one get with the Parasound over an EMO, besides THX Ultra 2 Certification and a little more Power, but only a 3 yr. Warranty vs. EMO's 5 Yr. Transferrable Warranty??

Transferrable Warranty?? Chime In, Comments, Questions, Answers -- Having owned a Parasound HCA-1205A for almost ten years before having it replaced by an XPA-5, I would expect you wouldn't gain much with the New Classic Parasound. The New Classic surprisingly have much less current capacity (45amps) available when compared to the Parasound HCA-2205A (60 amps) the present line replaced. Also, the New Classic with its warranty is a far cry from when I bought my Parasound with its five year parts and ten year labor warranty. Bought it in 1999, new for $1500. Retail was $2000 at the time. Having heard the Parasound HCA-2205A, an XPA-5 would be comparable in sound and quality of workmanship in my opinion. And if you did a search comparing the New Classic line to their original Parasound products they replaced, the original Parasounds are more desirable from a sound and quality stand point. Just for comparison, my old Parasound HCA-1205A had 45 peak amps available per channel and I thought it was still not enough for my Magnepan IIIa speakers. Once I went with the XPA-5, the Maggies had greater bass output which gave it a more balanced presentation overall. I suspect the XPA-5 has more. Also, my old Parasound had those adjustment knobs in the back for each channel, I never used them. Always kept them at the max THX level. So if you ask me, getting an additional 50 watts/channel probably won't get you much more for sound quality and peak sound handling. Because I run Maggies, current is more important to me. As a comparison, my top-line Pioneer AVR which is rated at 140w/channel has a peak current amp output of 4 amps. My old Parasound which I used with it had a 140w/channel rating as well but peak current output of 45 amps. The Parasound definitely sounded much better and less strained. And now that same Pioneer AVR is paired off with an XPA-5 which I am very happy with. I think you will be dealing with the law of diminishing returns every time you compare an Emotiva product with its competition.

I have a differential question for the group here, or perhaps for Lonnie & Friends(tm) at Emotiva.
Every amp lists "Topology: Fully Discrete, Dual Differential, High Current, Short Signal Path Class A/B" as part of its spec (all the UPA's and XPA's). But, the XPA-1 and XDA-1 both list "Fully Discrete Differential Referenceā¢ Output Stage with fully independent balanced and unbalanced drive stages". Is there any particular piece of engineering done on the XPA-1's differential design that make it better than the differential design in the UPA-1? I understand it has higher quality components, and more of them, but are they both fully differential signal paths, through and through?
I'm asking because I'm wondering if an XDA-1 driving two UPA-1's would be considered a fully discrete, differential setup, or if one would need the XPA-1's as amps to make such a claim.

Bill, Lonnie has stated that the XPA-1 is Emotiva's only fully balanced power amplifier. Thus, if you are seeking a fully balanced signal path it must include the XPA-1s powering your speakers.

I'm having a sort of 'duh' moment here. I read differential to mean balanced, whereas it really just refers to the ability to cancel noise between two offset voltages, as opposed to having a completely balanced signal path, end-to-end. Thanks for making me think twice.

Guys new too the Emotiva lounge..I have a HarmanKardon3490 in a 2.1 set'up..I just ordered two UPA-1!..with Vincent over the phone..this is just note to say thank you guys for the reviews on the Emotiva Amps!..and also in the Polk Audio Club house they are getting rave reviews!..soon i will be upgradeding..from my H/K3490 to the Emotiva Processor..but for my i will injoy the 2.1 set,up i have now!oh i do have the H/K2600 in a 5.1 set'up..with my H/K3490..useing a Niles A/B Amp switch so i can use just my Monitor70s for both...and it works great..Thanks again everyone!..HI-5s to all ya guys on here!

Nemesis.ie.ie...Thank you!..i have been eyeing them for sometime now..was going to go with the XPA-3..but when i called in about them..Vincent and i talk about what would be the best way too go..and after seein what you guys where have saying about theUPA-1s..i went with the UPA-1s...i stumble up on Emos...by accident on AudioHolics site looking up a review on the H/K3490...and the had this add of to the side about Emotiva Amps and this Babys face saying ..Angry baby ..says its time too get new speakers..i about fellout LMAO at it..the face on the baby that is..so i click the link too Emotiva..and wala!..thank you Sir!..so much for your time and post you have put in on here!..They really where of great help too me..

3 x UPA-1 up front rocks - as funds allow I plan to put them on every channel. Of course there is a catch - in exchange for the advice we expect pictures and a mini-review.
