Blind test held in Sweden comparing modern Swedish violins with old Italian violins, with (it seems like) a Swedish audience scoring the quality. Could have bias in setting up the instruments, tuning, bows, etc.? Judges could be more familiar with violins from Swedish makers? edit: not to mention that the people running the test could possibly be related to those selling the Swedish violins, thus having a stake in the results being a certain way.
All 55 responding participants were subjected to the exact same order and performances (!!!), so no randomization of order effects or different performances being superior to others (e.g. by chance, the first player playing violin B may have delivered a better musicianship and technique than when playing violin C, or anything like that. Maybe there is a tendency for people to score the first performance/violin better because they're more alert during that one, or maybe for the last, or something else.). Supposedly different excerpts were used "each time". Seems like little to no repetition. Statistically the experiment is very weak, even disregarding all the issues in the previous paragraph.
There's a lot to cast doubt on the results, whatever they may be. Also, even if you could make strong statements about the six violins tested, you can't immediately generalize that to all Strads, Gaglianos, etc.
Personally I strongly suspect that the old revered violins may not be as good as some modern violins, or in the least not really any better, but I wouldn't really say there's (very) good evidence, as in conclusive, to support that claim.
edit: I could've sworn the topic of blind testing violins including Strads came up more recently than the above "study". Let me do a quick search... found it.

Would be better to find the original paper rather than secondhand reporting, but I didn't find it with a quick search.
