Thanks once again for an excellent review and set of measurements
@amirm. That's now measurements of three of the top four speakers from Wirecutter's / New York Time's
Best Bookshelf Speakers (priced ~$100-$500), which they say was decided by blind listening tests using an ABX switching device. They also reference Floyd Toole and mention they've taken training courses from Audio Precision. Although obviously not to the level of a scientific study, this is far better than most audiophile publications which don't even attempt any blind testing at all.
Their order of preference from these blind tests seems to agree with the preference scores calculated from the Klippel data, which adds corroborative support to both. It would be great to see if this holds further by getting Klippel measurements of their top pick, the Q Acoustics 3020i, or the 3020 (without the i) which was their previous year's top pick, and can be had for a more reasonable
$229 a pair from Amazon. (The 3020i seems a bit overpriced, getting outside the 'budget' range at close to $100 more, for what I suspect is minimal if any noticeable improvement over the 3020 model.)
