“I believe that I found the right combination of tubes for my Yaqin M13S amp. These Gold Lion KT77 tubes are the final piece of the puzzle. They replaced the original Chinese blue tubes and also the EH 6CA7 tubes that I had rolled in. These Gold Lions gave me the sound that I was looking for....in combination with the Brimar 12AU7 and the Gold Lion 12AX7. (all purchased from Upscale Audio), my amp sounds warm and detailed throughout the audio spectrum. The soundstage is startling, and dynamics are so much more improved no matter the genre. My system never sounded better. All based on the reviews posted here. I think that I’m set for a while!”

“What can I say? Never knew my Primaluna could sound better then it did. Wow, just wow. Loving these replacement tubes, took about 30hrs if break in for me and I’m enjoying pure audio bliss. Thank you upscale for the easy and quick upgrade. I don’t think I’m buying tubes anywhere else.”
