SHUGUANG TREASURE CV181-Z
Overall it's a lovely sounding tube. I ran it with the Bendix 6080WB, it's a great match for it. Clean and detailed high end that is a bit airy. The low end can be really detailed, no mud. Soundstage was definitely notable with superb channel separation. Overall, pretty impressive and it makes me happy to know that this is new production. I should also note that both tubes come tested (mA) from the manufacturer, both of mine have perfectly matched, 8.5 mA for all four triodes. I tested them myself and the two test right at NOS, however the second triode (Gm) is 10-15% higher on each tube. It doesn't bother me but it makes me wonder if their numbers are made up. Anyone else have a similar experience? I have heard these can have a lower lifespan vs old stock. But I do recommend trying one out if you can.
