The fact that Phil Ward in that article makes this claim at the beginning makes the whole article highly suspect:
"But through a technical analysis and investigation of four speakers — two that carry the 'hi-fi' label and two the 'pro' — I'm going to try and discover a little about the typical differences between them."
Certainly, he debunked the generalization that pro audio speakers always have a flatter frequency response than home audio speakers because of the measurements of the DM303s, but one cannot then make one's own generalizations about home audio speakers vs. pro audio speakers by only looking at two of each. That's not enough of a sample set.
I'm confused by that statement. Are you saying the DM303s would be more fatiguing? Generally fatigue is related to speakers having a bright sound, not a neutral sound.
Anyway, I own the Ascend Acoustics CBM-170 SEs, and have owned a variety of pairs of passive speakers in that price range. I've also listened to many pro audio monitors in the $500 to $600 range. To my ears, the 170s sound better. They have a very neutral response and also incredible transient response making them very accurate. This is why I suggested them and the Arx A1bs. Both of those are Internet speaker vendors. Because they don't have to work a middleman's cut into their price (another reseller) and they don't spend a lot on advertising, the speakers are fantastic price/performance values and can compete in quality with home audio speakers that sell for $600 or $700 at your local hifi store.
