1 Pair of Tube Simulator in a Pipe (left and right channels) balanced and unbalanced. These are interesting items that add the sound of tubes when inserted into your audio system before your power amplifier. If you have a receiver it will go between your audio source and the receiver. They have both XLR and RCA inputs and outputs. Give them a try and see what they do for your audio system. I’ll cover shipping to CONUS at the asking price. Zelle preffered
