This time around Simaudio was was providing the current for the M1s, and their amazing Sopranino Super Tweeters (which I’m still hoping will come my way for review). The Moon Evolution Series 700i integrated amplifier ($15,000 USD), and Moon Evolution Series 650d DAC/transport ($5,000 USD) proved to be a fortuitous pairing with the M1s as they kept a steady hand on the classy stand mounts with incredible tight-bass domination. If you’re familiar with Simaudio gear, I’ve found you can recognize their sound very quickly for what it is: just a warm hair west of neutral with almost no coloration to the midrange, and excellent top-end extension without going dry on you. Upper frequencies are not sweet, but they certainly don’t fatigue one either, and there is a real air of sophistication to the Moon sound with transparency, and precision not shading into that grey area I call accuracy.
ENIGMAcoustics is working on a prototype super tweeter to add to their current Sopranino offering called Arioso. Estimated street price as a stand alone add-on is pegged around the $2,000 USD mark. Crossover options for the new design will be similar to the Sopranino, but there the similarities end as on the Arioso the electrostatic panel fires directly up, and into the cone-shaped dispersion unit which allows for non point-directional presentation to the ear. Color me curious, as the current directional model is mouth watering in its sonic abilities, so I’m looking forward to hearing this when it’s ready for prime time. Since I gushed without shame over this gear at AXPONA, this time around I’m only going to say that this was again, another outstanding sonic offering on tap from ENIGMAcoustics, and Questyle.
