Description：  The Psvane T-series black bottle tubes are a further development over the highly sought after Shuguang Treasure Z-series, which was originally first launched by Grant Fidelity in Jan 2009 in North America as Shuguang’s first take on high end vacuum tubes.  The elite team of engineers who contributed to the Treasure Z-series have done further fine tuning of the Z-series in the past few years. The further development has created a new series called Psvane T-series...
