I agree with Teres' comparison of the Voice with a Jade Platinum. Of course revealing that a cartridge is faster and more articulate than a Koetsu will win us neither friends nor golden ear awards. Theyll be crying "Death!" on one side and "Duh!" on the other!
OTOH, if a Voice sounds faster or more articulate than a UNIverse then IMO something was amiss. From what I heard in two rooms at RMAF, neither the Voice nor its bigger brother would even match the articulation of the Atmos, much less a UNIverse.
I definitely agree the Voice is "smooth and easy on the ears" though that's a listener preference and not a characteristic of any live music I listen to, especially if its complex. Understanding how it goes about sounding this way may help you make a decision.
The Voice goes smooth and easy because it collapses harmonic overtones toward or into the fundamental. Example: an 16kHz overtone is attenuated and some of its energy feeds the 8kHz overtone, which is also attenuated and some of its energy feeds the 4kHz fundamental, etc. (In the Voice this can leave a trace of mud on the fundamental; the Strain Gauge does the same thing but more cleanly.)
Components which do this - and there are many, not just cartridges - can make the sound simpler, smoother and easier for a system to reproduce and for the listener to hear.
Quite a few cartridges (including UNIverse, Colibri, Lyra Olympos, XV-1S and even the Atmos) deliver a more complete spectrum by reproducing rather than collapsing higher order harmonics. Of course that demands more from a system - which must reproduce all those harmonic complexities clearly. Distorted upper mids and highs sound anything but smooth and easy, as we all know.
The Voice can indeed produce a powerful, fast, smoothed and easy sound. It's not clear from your post if that's your goal. FWIW, no SS phono stage that I've heard reproduces harmonics completely either, so it's possible the Ayre might let you enjoy everything the Voice does without missing what it doesnt.
