“I will not buy tubes anywhere eles, a perfectly matched quad that I haven't had to bias at all because they were perfectly biased and stable. Loved the Gold Lion Kt88's..Upscale Audio is a trusted source.”

“As usual, Upscale Audio delivered quality. I purchased the KT88 Gold Lion Cryo treated tubes. Immediate improvement. The tonal qualities are improving with each use. Cannot recommend them enough.”

“The Gold Lion KT88 quad set of output tubes is a big improvement over the Penta Labs KT88s That I previously had been using! Smooth sounding and better high frequency sound. And as they get burned-in the Gold Lions will be even better.”

“Gold Lion KT88 driver tubes are a huge improvement from the primaluna EL34 stock tubes they are replacing. Much better base and clearer highs. Also noticed better separation of instruments. I am using a primaluna evo 300 intigrated.”

“The Genalex Gold Lion KT88 power tubes that I recently ordered from Upscale Audio are the second consecutive set of Gold Lion KT88s that I have purchased for use in my VTL ST-150 power amp since I purchased the amp in late 1993. The amp originally came configured with 6550C power tubes and I had to replace the 6550s each time after approximately 2-1/2 years of use. The last two times I retubed my amp with 6550Cs, I purchased Svetlana SEC "Winged C" 6550Cs. I was very happy with the sound of the "Winged Cs," but I still only got approximately 2-1/2 years of use out of them. My first set of Gold Lion KT88 tubes are now five years old and were still going strong, but I had begun to worry about tube failure, so I decided to purchase another set (two sets of four tubes) and hold onto the others for spares. I enjoy the sound of the KT88s a lot, but I wouldn't necessarily say that I prefer the sound of one type over the other. I listen to many different genres and styles of music, but I almost always seem to gravitate back to different styles of electronica when I don't have a strong feel for what I want to play on a given evening. Both the Svetlana SEC "Winged C" 6550s and the Genalex Gold Lion KT88s definately haven't left me wanting in the bass. They seem to drive my Coincident Speaker Technologies Total Eclipse speakers down to or near their rated 20 Hz in the bottom end. The many reviews I read over the years disparaging the low end of most tubed equipment compared to solid state, have certainly not been my experience. At the other end of the scale, female vocals are beautifully rendered and don't ever become shrill in the upper registers. Violins and pianos have never become shrill or distorted in the upper registers, either. The mid-range is full and rich, exactly what I pictured tubes sounding like in my head prior to buying tubed equipment.”
