For concepts 1 and 2, the idea is a play on “Tetris”. I took inspiration from the numerous times I saw the “Pass amp tower” outside your CES Venetian showroom. I think it would be a very identifiable way of advertising your components. Both concepts can be arranged with different Pass components combinations.
Tetris concept 1 - Hard lighting on objects placed on an even surface, yields to a more natural perspective on product. Surface can consist of a color that matches or contrasts the product.
Tetris concept 2 - Soft lighting on objects placed on a stylized vertical arrangement. Can be made of different components (mono amps/preamp) or amp tower of 3-4 pieces. Background and surface that product is placed on is black, with an option for white.
