I have my Aperion Audio Verus III Grand V5B bookshelf speakers topped with Aperion Audio MKII Aluminum Ribbon Super Tweeters. The sound quality is incredible!\n By themselves the Verus III Grand V5B speakers have incredible open detailed highs and midrange rounded out with tight punchy bass. Top the speakers off with the MKII Aluminum Ribbon super tweeters and it takes you to a whole other level.\n I am currently listening to some Jazz on Amazon Music. 16bit 44.1kHz and 24 bit 96kHz. It honestly sounds as if I am listening to speakers with a tweeter, midrange and woofer combination. By using the MKII super tweeter I get a great extension of openness and detail in the highs. Another excellent bonus is that I also get a boost in the midrange. The midrange opens up even more and has more detail. The sound reminds of my Infinity 6 Kappa speakers with their soft dome midrange. I am a big clarity and detail guy. With the Aperion Audio Verus III Grand V5B speaker and the MKII Aluminum Ribbon Super Tweeter I am getting plenty of both!
