I have bought quite a few items from them and never been disappointed. They are my go to dealer if I need tubes or just about anything audio. Kevin and his crew simply know what they are doing, and how to treat people.
Upscale Audio is up front with customers
I have not bought from Upscale before but have enjoyed their videos. The approach Kevin Deal is taking with his customers is really up front and honest. A good model for how to communicate in audio, and in general.
