Over the years the LS1 has seen some significant improvements, reason why the current LS1 sounds better than an LS1 from a couple of years back. We also introduced a new flagship product recently, the LS1be. Whenever we improve our products, we ensure our existing customers can profit too. So we like to offer them the option to update their LS1 to the current level or even upgrade their LS1 to the level of the LS1be! Please read the linked brochures and contact your dealer for more information.
