1, PSVANE T-Collection series MK II use the Carbon Microcrystalline technology. Carbon Microcrystalline is a kind of very stable absorbent (material), and it has excellent heat transfer performance. Carbon Microcrystalline make up stabilization of the electrical performance inside of the Vacuum tube.  2, The PSVANE T-Collection series MK II tube socket is made with Teflon. It is very low electric inductivity, very low dielectric loss, and high breakdown voltage, high electric volume...

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...

Description：  Got the Psvanes. They replaced KT88 treasures and prior to that Pentas and gold lions. There’s just no comparison. If I had to really quantify what I’m hearing I would say the Psvanes just have confidence to sound amazing where as the treasures sound awesome, but polite and demur. in either case the treasures and the Psvanes beat the pants off of the GLs or anything else for that matter.  Pez on AudioCircle  The Psvane T-series black bottle tubes are a...
