“I replaced the gain tubes on my Rogue Audio 180 mono blocks which power Vandersteen 3A signatures. I did so after having changed the power tubes from Gold lion KT88’s to EH KT 88’s. The former have a very smooth and almost syrupy mid range, the latter not so much. However, these new gain tubes appear to enhance the bass and sweeten the sound more to my liking. Highly recommended and thanks to Kevin for his video tutorial on the impact of the small signal tubes on an amplifier.”

“Thank you Kevin! I just found out about Upscale Audio recently from a fellow HiFi intrigued friend who recommended it to me. Love the service, enthusiasm, products, and product knowledge that comes with the Upscale Audio experience. Looking forward to purchasing more merchandise from the organization as time goes on.”

“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!”
