I really love the Sonata Pro HD, not only because of the price, but also the form factor, usability, simplicity, and SOUND QUALITY! With the Sonata HD Pro, I have never found me needing to go for my bigger system to get sound quality, the sound quality is insanely good and I have yet to find any shortcoming in sound quality, I am not saying it is better than the high-end product, but personally, I think that it is as good as the Chord Mojo and JDS Labs Element if not better, I can’t believe this as well but the way it makes music sound is really staying true to the record and maintain all the technicality pretty well if something powered by USB can be this good, why should we go for something bigger, more complex and expensive? I am not going to hype about it, but it is really good, it is just 45USD, miracle, man, a real miracle!
