Critical oppositions made using inadequate equipment.

What is the best shape of leaf for effective diffusion when situated behind loudspeakers?

" The biggest issue I see with the out spoken people is there lack of experience with live real music. They always fall back on detail and pump up highs. They use the terms air around instrument , black background, neutral, sound stage, etc etc ... In all the posts did anyone ask you what your goal is. What are you looking for. What is your musical background.? What music do you listen to? Etc."

Tom, I really have to agree with you on this. I spent a lot of time during the decades of improving my system in getting more and better details, slam, nuances of transient, etc, while the overall gestalt of the music suffered. It is easy to let the analytical side take over and look at one variable at a time and loose the big picture. It was season tickets to the symphony ten years ago that brought me back down to earth and while my system has all the details and nuances of former systems they are not lite up as if in a spotlight, they are part of a more musical whole. But I think often you just have to chase the obvious before you can figure out how to find what you really want.

 No, sorry I can’t tell you anything about the plants, this is not my strong side. Let’s live this topic to Darko and chakster :)… however I could tell you about other interesting stuff like beautiful women, swing jazz and surf rock, the game of tennis, rifles, handguns, boats, deep sea spearfishing, rare whiskey and old propaganda posters from around the world. I’m surprised why you still confused about what is non relevant equipment…. Isn’t it obvious that low quality cheap speakers for example is non relevant to evaluate components and make serious conclusions and suggestions to others about this components!?

@ghdprentice , Really? Last night I saw The Tower Of Power in Hampten, NH at the Casino Ballroom. The band was phenomenal but the sound system SUCKED!! There was distortion behind the singer's voice but not the horns, maybe a bad mic. There was a lot of sibilance which made me squint once in a while. It was a mono system. The bass player was buried behind the bass drum which BOOMED. In short, the three live records of theirs are superior in every way. The individual instruments are beautifully outlines. I can match the level without any stress or sibilance and I can clearly here each bass note. The bass drum thuds with assurance. 
Certainly, people who have been to indoor stadium concerts will tell you the same thing. If you can get a good live recording the sound can be much better at home. If you want to compare your system to the real thing than any acoustic setting will do, classical, folk or Jazz. Electrified bands that are playing through their own amps Like the David Holland Quartet are also great especially if they keep the same set up on their live recordings. Very Cool. Now, what were you saying ghd?

tomwh, What Do You Want From Life?  Yes, I like bass very much and I like midrange and treble. As I explained above there are many instances were a recording is subjectively better sound than the live event. But there is only one live just like there is only one right color calibration for projectors. Having measured several systems besides my own I can guarantee that the majority of systems/rooms are not properly calibrated. Some of them are way out with 10 dB and over deviations from flat even up high. Not only that but the frequency response of the left and right main speakers can differ by 10 dB.  The colors are way off. Most of this can be easily fixed with the right equipment all of which operates in digital. This is a leap analog folks are scared of making. If you like vintage sound go for it but, that is not where accurate reproduction lies. There are certain things that have to be done like getting the sound balance/tonality that you like, adjust the response of the individual loud speakers so that they are within 1 dB of each other from 100 Hz to 12 even 16 kHz, Create a two way cross over for subwoofers with a 48 dB/oct roll off and match them with the main speakers in time and phase, create a brick wall rumble filter that drops at 80 dB/oct from 18 Hz and finally Boost the very low bass +6 dB at 20 Hz. This gives you that live feeling at slightly less than ear shattering volumes. 
People laugh a this approach but some of you know better. How do you know that a system is too bright if you don't know what flat sounds like?
It gets back to that calibration thing. You have to calibrate your brain. Experience is the best teacher.

live music is not always a gold standard for sound quality. I could remember the shame sound at concert of Pink Martini at Wolf Trap several years ago it was total disaster. However Depeche Mode concert was just glorious in sound.
