“This was my first time swapping out tubes. The info on your website helped me make an excellent choice. Much improvment over the Stock Mcintosh tubes in my MA352. Better Bass, Midrange and top end. Very Happy with this tube. Fast shipping was the icing on the cake. Thank You Kevin!”

“I’m very pleased with them. I have a McIntosh MA 352 and they opened up the sound over the stock tubes.”

“As with the EL34s, the Upscale Audio website helped narrow down the brand. I've had defective tubes in the past (not from Upscale), so the ability to choose the level of screening really increased my confidence in purchasing.”
