Welcome to Squeeze-upgrade

The address for innovative upgrade products to improve the sound quality for streaming audio players, D/A converters, Mini-PC and headphone amplifiers. You are at the homepage. 



Brief introduction

The basic product of Squeeze-upgrade is the SBooster, an economic and quirky addition to your existing switch-mode power adapter (wall wart adapter). The SBooster enhances the sound quality of audio devices powered by a switch-mode adapter.


Our other product is the Best of Two Worlds Solution. This is a high end linear regulated power supply solution with the SBooster integrated in the DC power cord. The Best of Two Worlds Solution improves the 'digital' circuit and your music will sound more dynamic and more natural. Also the background noise will be totally gone. The additional SBooster creates a perfect soundstage, a fantastic placement of the voices and instruments. You will enjoy even the smallest detail.
