It’s made and rendered using Blender. The Hi-Fi Rack (Shelf) is there just for render of presentation. All formats includes Amplifier only. This is amplifier and this is my own design. Design is based on real audio amplifier that I designed and built by myself 13 years ago. So, only one exists on the world. (https://lh5.googleusercontent.com/-Tjy5xzziV98/TlgBp73RquI/AAAAAAAAAbc/VXC24ZVrO8w/SAM_1765.jpg) This Amplifier is the part of my virtual Hi-Fi system.
Note: Shining parts have a UV map, but it is not used for the texture. Instead Reflection is used.
