See, when I read people say

I can now say that there clearly IS a difference in seperates versus AVR's no matter what Blind articles seem to state. I have been experimenting with various music and going back/forth between my Denon and Emotiva. At louder levels, say 95dB or more the music is more vibrant, fuller, and the soundstage seems to have more depth. Also, I've noticed that when I have the Denon at the same levels, I can't listen as long, almost like ear fatique or whatever. Not sure if this is contributed to distortion, less headroom, or whatever.

I think I've decided to go with what my perceptions are noticing, versus some article or white paper. Even at lower levels I can detect a richer sound and I'm sticking to that.


Then ask others why do they think they need an amp, it makes me wonder.

I guess I ask because in most situations people don't need the extra amps, as they will never make use of the extra power in their room. Seems I've heard you ask people how big their room is and how loud they crank it up, no?

In my situation, my room is 2-3 times bigger than most rooms. I enjoyed the extra ummmpfff when cranking up my 80's to concert levels. However, those opportunities don't come often with the family always around, and besides the Denon 3808 plays louder than most people could handle, even in my huge room.

Don't get me wrong, I do miss my amps, but my companies financial situation drove me to needing the money. In addition, HT movies are primarily what gets played at the Plex.

Like I said in the above quote from the archives, 95dB's and above I did notice a difference. I never said there isn't a difference did I? The majority of the time I'm not listening to music at insane volumes, so I decided the extra headroom was just that, extra, and not being used often enough.

For all HT movie needs, and most music requirements, the Denon alone is adequate at 130 watts/ch. I don't see a problem in asking people how large the room is, and their listening styles for music. Why have them spend all that extra money for power they will most likely never touch for most situations. I guess I don't want to mislead people.

I guess we all have the right to change our views.

I'm still in the "buy as much power as you can afford" crowd.

What is all this talk about 'calculators, room size, needs' and the like, I thought we lived in America (well, and Canada)? You know, home of things like the 'Whopper', and the 'Sears Tower' (CN Tower for the Canadians), and the 'Mustang GT', etc... In other words, I thought this was the land of 'more'!!!

If we all took our calculators out when we went to the restarant all we'd have is a salad and a water and the 'Whopper' would cease to exist. Building humongous towers like the 'Sears' and CN' would be sensless, and nobody would have to worry about any buildig being highter than say 15 stories. And we'd all be driving around in either a Ford 'Focus' or a Honda 'Accent' getting gobs and gobs of miles per gallon while making do with a scant 80 horse power.

So let's put those silly calculators away before someone hurts themselves shall we? We wouldn't want anyone to not get more than they needed would we? Not here in the America's.






Oh, and yes I love the way the XPA-3 drives my M80's to insane levels of volume btw...

Why do you ask this every time someone wants info on an amp Randy.

Because its a reasonable question? How much amp power you need is a simple physics problem and there are calcuators out there that will give you a very close approximation of your power needs given room size, listening habits, distance from the speaker and speaker efficiency.

I'll crawl back under my bridge now. ;\)


A while back we were talking about the power needed to run a system and I remember Ian commenting on it.

I don't see any inconsistency between what Ian and I wrote. He was talking about large rooms and a little playing with a calculator will verify what he says.

In a small to moderate room, you will never need a ton of power, but when your room gets big enough, you will run out very quickly

I am willing to bet that if you move from a 1700 cu. ft. room to a 3000 cu ft room, you will loose a few db of room gain. I am also willing to bet that in a concrete bunker like my apartment, you will gain a few DB due to increased reflection.

I still like my calculator post.

OK, heres some examples using the M80.
To listen at 90 DB with 15db of head room for peaks:

8' listening distance = 50w
12' listening distance = 103w
15' listening distance = 175w Look ma, I need external amps!
18' listening distance = 275w mine's bigger than yours is

To listen at 95db w 15db headroom

8' = 157W WHAT?? YOU LIKE MY EXTERNAL AMPS? ;\)
12' = 344w
15' = 509w
18' = 760w

In my apartment I can listen at reference from my kitchen. In some of the rooms you guys have, my receiver would barely keep up in the main room.
