Keith, so if I only need only 100w/channel, I will not hear a diff between the upa200 vs xpa1 vs xpr1 in a stereo setup? It's usually a leap of faith to ask someone else what you will (or wont) hear. |

BTW I modified the very thick powercord with a Belgian type heavy duty powerplug. Is that anything like a heavy duty Belgian beer? Tripel Phase!  You probably missed out on the occasion tot try Westfleteren? It's only to help fund their new building that some 15,000 boxes with 6 bottles were sold in USA a couple days ago. My brother-in-law is a keen "user"... When the monk's website says they have some fresh brew avalable, he hangs about an hour on the phone before he gets trough to order a case with 24 bottles. Then he has to go pick it up at their monestry. Not avalable in any shop! Although they did a distribution like in USA earlier here in BE also to fund said building. Supplies lasted one day. I was over at my brother-in-law last Saturday and he was so kind to serve me one... Now you are jealous... ;D Actually, that plug is normaly used for pro tools, waterproof et all. To get back on topic: the question is whether one can buy a better amp, suitable for all purposes, regardless of power for $1,699 $1,449 than the XPR-2? I doubt it. A pair of XPA-1 will come closest at $1,698 while the other brands aren't even in the same street. |

Keith, so if I only need only 100w/channel, I will not hear a diff between the upa200 vs xpa1 vs xpr1 in a stereo setup? Well the question of the day is how do you know you really only need 100 watts per channel. You have to think of those quick loud dynamic transients like the sudden hit of a piano or the kick of a drum. most listening is done at a few watts to get you around 80 to 90 db comfortably but you need the headroom which may demand several hundreds of watts on a loud piano strike. One post here said that to capture the true dynamic range of a piano hit it could take upto seven hundred watts of power over a very short period of time. well agree on the headroom required on transients... I didnt ask what I want to know directly. I shud have asked when operating well within UPA200 power ratings, does Emotiva as a company feels there is SQ differences between UPA200, XPA1 & XPR1? I want to know Emotiva's statement on the SQ between its amp... will the 1st 100w of UPA200 sound the same as the 1st 100W in the XPA1 and the 1st 100W in the XPR? Are they designed to sound the same or different? |

So Keith, there's a number going around that an XPA-1 is biased for 10 Watts of Class A before going to B, will Emo release a "Class A Rating" for the XPR-1? Going by the idle current and heat output reported for the XPR-5 I'd expect it to be lower, but it keeps being asked, so ...? To answer your Class A question, its 0. The XPR-1 is pure Class A/B from the 1st watt |

The XPR-1 is pure Class A/B from the 1st watt If it has no Class A power then it's a Class B amp. Class A/B amps have some Class A power before switching to B (when the second device turns off). However you still could be right when you say "from the 1st watt", it could be Class A below 1 Watt. |

That's what I thought as well, but the above is what emo told me. Never the less if you are buying a 1000w amp your speakers should not be efficient enough for less than 1 watt to do much.

Well that's what the sensitivity rating is all about. I don't know about you, but 85+ db at 1 watt is pretty loud to me. |

And this is why I am always amused when folks declare that you *must* have a 1000 watt/ch. amp to enjoy rich and accurate musical playback. How did we ever muddle thru with *just* 100 watts/ch. for so many years?
It's somewhat akin to the "horsepower" wars conducted by the various motorcycle mfgrs. When I was growing up, a 500cc bike was a BIG bike, something you aspired to after riding "regular" bikes for a decade or so. And this was when 500cc bikes had about 35-50 RWHP.
Nowadays, complete newbies are encouraged to hop aboard a literbike (most have well over 100 RWHP) and let 'er rip, despite the fact that 500cc bikes have in excess of 75 RWHP. A recipe for disaster if ever I saw one...

Since our minds process what we hear, you know we can't truly enjoy the music if we know that there is a more powerful amp somewhere that might sound better.  Our ears may hear the same signal but the brain processes it differently depending on how the flowchart is set up. |

I guess Emotiva knows most emo buyers dont hear differences between amplifiers so they just build newer models with higher wattage to attract upgrading. Even the XPA1L is about higher class A wattage.. Hope to see Emotiva 1 day to produce a higher quality amp with less emphasis on numbers.

thanks for the welcome. As you saw I`am a new participant in this lounge. Actually i have none Emotiva products, my amplifier equipment is a Cambridge 840 E /W combination. But if somebody could explain why buying two xpr-1 is a better selection enjoying stereo. I miss a Music Player, which could be connected over ethernet to a router, playing tracks from NAS, but stop this is offtopic here |

Are you comparing a 1000 watt amp to a 400 watt amp and saying that the 1000 amp has more power? As sexy as 1000 watts looks, nobody needs this kind of power unless your listening room is 4000 sq.ft. plus. Which means that you have speakers that can handle several hundred watts. But us males are known for buying our toys, the line forms at the right! |

Please explain.. not sure. don't know what exactly what has been compromised in the current design / choice of parts to make it value for money or cheaper to produce. Im not a diy guy but if u are and genuinely interested to know about higher quality parts, can post this question in diy forums. I recall diyAudio did have people who self upgrade / modify the XPA1. Oh, one thing I can see is the connectors on XPA1s, can definitely use higher quality ones, eg the wbt 0710 series. whether or not using these parts can lead to better sounding gears is of course a separate discussion. |
