2pcs Shuguang Natural Sound CV181-T Matched Pair Vacuum Tubes Replace 6SN7 6N8P

I heard rave reviews on these tubes, and after receiving my matched pair I have to wholeheartedly agree. While I only use a single tube in my headphone amp, I ordered the pair just in case. They arrived in a beautiful cardboard box with a magnetic latch. They are quite large, both in height and base diameter, thus making the act of "rolling" more like placing. Gorgeous looking and great sounding.

These sound as good as my JAN-CHS-6SN7W metal base tubes in my 45 amp. And those sounded better than every other 6SN7 tube I tried.

These tube sound very warm and have good bass.

Excellent seller! definitely would buy again.

Bought matched four pair Of these but they don’t fit in my Cary SLP-98 preamp . I don’t know what to do now
