Crikey, I am having mediator fantasies, being the 4 between a 3 and a 5 star review.
To be honest I can see both points of view ... this performance wouldn't rank as anything near over the top. Certainly the violinists don't cane their bows, but I'm totally OK with this. I like that, in this performance, it's possible to absorb the detail of Prokofiev's amazing ballet (in suite form of course).
This relatively more subdued performance is helped inordinately by a very dry acoustic. In 5.1 this works very well, and certainly in technical terms this is one of Telarc's better efforts, beautifully balanced. However, in stereo (both CD and SACD) it's not so great. For some reason the stereo mix does lack a bit of power/punch. Given that power and punch certainly have a place in this work, that is a tad problematic.
Still, if you're after an SACD of Romeo and Juliet, I think it's quite likely you'll find this is (currently) the best of the lot. Jarvi handles the tempi really well - he keeps control of any tendency to accelerate/rush into the more dramatic/passionate pieces, but he doesn't linger either ... he doesn't drag out the more reflexive sections.
I am not sure I could answer the question 'is this primarily a horizontal or vertical account?' I really don't know. It strikes me that it is essentially a very balanced account. What it perhaps occasionally slightly underplays in terms of expressive possibilities is, I think, compensated by detail.
