Photon 46 has made a number of valid and relevant observations. Your preference for one cartridge over another may have more to do with the cartridge compatibility with your turntable, arm and phono stage than it does with the relative performance attributes of those cartridges.
You have compared a high output MC cartridge (the Dynavector) with a pair of MM cartridges. The MM cartridges have output levels that are roughly double that of the Dynavector cartridge, which explains your observation that the Dynavector did not sound as loud. It might be that your phono stage does not have sufficient gain to pair ideally with the Dynavector cartridge.
Other factors to consider include arm/cartridge system resonance frequency and cartridge loading. Each of your three cartridges will combine with your tonearm to produce a different resonance frequency as a function of their different weight (ranging from 6.3g to 8.6g) and compliance (ranging from 12 to 22) specifications. As a result, your preference for one cartridge over another might, at least to some extent, reflect the relative compatibility of your tonearm/cartridge combination in achieving the ideal resonance frequency in the range of 9Hz to 11Hz.
Another factor that is even more important than system resonance frequency is the load resistance - and, for the MM cartridges, the load capacitance - of your phono stage inputs. Input loading has a significant effect on the sound of a cartridge and, again, might have led you to prefer one over another due to inherent system synergy factors as opposed to any real differences in the performance capability of the cartridges.
As for the comment that the reviewer made about imaging (i.e., the position of the musicians) and the reproduction of hall reflections (i.e., the sound of the music bouncing off the walls), these factors are affected by all the components that comprise the audio system, not the least of which is the listening room. You need to have a system that is capable of excellent imaging in order to determine the relative merits of cartridges in providing palpable, realistic images of the individual performers within the soundstage. Similarly, you need to have a very resolving system in a listening room with good acoustics in order to hear hall reflections clearly and to begin to discern the relative space and size of the original recording venue. This is a tough thing to achieve, and it is also dependent on starting with a good recording. Many of us have spent years developing our audio systems to a point where the system can begin to do justice to this sense of space, hall reflections, and original recording venue.
Almandog, if you provide us with some more information regarding your phono stage or preamp and the components that comprise the rest of your system, you will likely get some helpful comments from people who have experience with those specific components.
