“Awesome recommendation from Upscale Audio. How Kevin described the sound signature of these NOS Mullards is exactly what i'm hearing now from my tube amps. Yes, the midrange and highs they produce is just incredible. Great job Upscale.....”

“Loving the combination. They already sound good but patiently waiting for a little more base as they break in. Very happy with both purchases. Also impressed how fast they got here.”

“Wow! Replaced my Heerlan made Amperex with these beauties. Even in my very modest Jolida phono stage the improvement across the spectrum was remarkable..Mates perfectly with my DV 20x2h...The best upgrade to my system in years. Worth every penny.”
