Lite in the context of the Star means a reduced functionality (ie no CD drive). However, I’m sure Naim would argue that it’s been improved in other areas.
For some this might refer to reduced functionality, or even redundancy. But I understand the reference to evolution.
AI suggests lite is a marketing term related to fewer ingredients or a simplified, stripped down version. But Adam is correct that an anglophone should properly refer to ‘light’ in these contexts.
