The ZBOX is a stand alone tube output stage for your CD player, DAC, Computer, or any line level device. Until recently it has only been available in 120vAC. We now offer it in 100/120/220/240 VAC making it a world voltage compatible product.

This outstanding device that makes CD players sound better has enjoyed strong sales since its debut several years ago. It remains the same today, with the exception of an improved power supply.
