You may have heard or told “it sounds analog” or “it sound musical” when listening to very good sound.


Such expressions have been used to describe the sound that is close to the real charm in the actual performance stage or that is richly expressed in musical nuances rather than realistic charm. However, whether it is the former or the latter expressions, the meaning of these expressions could only make sense when the feelings of very dedicated and dynamic live performance reach to our ears and touch our mind.


However, with most audio systems, it is very difficult to experience such real charm or musical nuances, and in fact even it is also hard to reach to the sound with the ultra high-end audio systems too.


So SOtM, to overcome such situation, has been developed from SATA filters, tX-USB card series and other equipment since for the first time when people got into computer audio which have settled into the essential part of digital audio now days, but still it is a fact there is a lot to overcome to improve sound quality.


Facing up to the fact, the tX-USBUltra is designed to reach to the goal which improves sound quality. It works as a hub by receiving and distributing USB audio signals, but regenerating the USB AUDIO signal by the high-performance super clock module, sCLK-EX, installed inside to the product, so that sound could be superior to any other USB audio product and step into the upgraded sound.


The mid-low range sounds very deep, detailed and earnest, the high range sounds not distract but extremely delicate and open, and especially the very low range gives you transparency you have never heard before and gets you very natural and solid texture of performance.


The improvements with tX-USBUltra in sound can be felt even in the ultra high-end system which values over hundreds of millions of dollars, it can be simply judged by the best USB audio device up to date.


Whatever is, it is very difficult to go beyond any limit in any field. At the heart of this product is the built-in super clock, sCLK-EX, which has been developed over the years, allowing you to experience a whole new range of sound and introduce you to go beyond the sound.


The tX-USBultra would show how to upgrade the sound quality and improve the dignity of music by in-depth research into advanced audio technology.
