I don't disagree either, in general AVR amplifiers don't produce the same sound quality as any Emotiva power amp, even those with a lessor power rating. My point was that I wouldn't expect a quality improvement just because of the higher wattage rating. From the poster's perspective, replacing the internal AVR amplification with an XPA-3, IMHO there would undoubtedly be a sound quality improvement with the bonus of a sound quantity improvement if so required. In summary, I'm not a subscriber to the view often expressed that "double the power is only 3db, so adding a power amplifier is a waste of time". I'm not counting the db's I'm listening to the music. Just as I am not subscriber to the need for 100's of watts of power with a high efficiency loudspeaker. IMO it is the better amplifier that is shining through and not the power. Double the power IS only a 3db increase! That is unless you are into modifying the laws of physics! Not arguing, just my opinion! A valued opinion Chuck. My view is not at all dissimilar, but what I notice is that there are lot of the opinions expressed along the lines of "you don't need the extra 100 watts / 3 db hence you don't need the power amplifier". In my case, for sure I don't take advantage of the 250 watts in the XPA-1L's, I probably hardly ever get much past 10 watts. They are capable of about 4 db more than my Denon AVR but I never use it. Obviously the sound quality improvement is outstanding, but some people (not suggestion you would Chuck) say that since I don't use the 4 db therefore I shouldn't bother with a separate power amp. I of course experience the law of diminishing returns, at some point there's still 3 db to be had with a bigger/better amplifier, but extra sound quality isn't sufficient to justify the cost. But I've yet to experience that in an AVR to power amp upgrade. Cheers Gary |

It was rated at 135W 2-channels driven 8 ohms. The power amp section was replaced with a UPA-2 and a UPA-5. 125W all channels driven 8 ohms. The difference was night and day and I still use the Emotiva amps with my XMC-1. Now sounds even better. I can only equate the difference being that the Emotivas are better amps - SQ? Screaming the Klipsch Heresy is using < 10W. That gives over 9dB of head-room. You can't run without some reasonable head-room, but all the Klipsch need is a 100W amp. This is why I hate to see the UPA line going away along with the smaller size XPA line. "What this world needs is a good 5 watt amp." - Paul Klipsch |
