I have already spoken to two. The upgrade involves adding HDMI and eARC, not sure if they are adding a USB connection or newer version of bluetooth.
Since they are for my computer desktop and I purchased a Toping D10 DAC for my Macbook Pro M1 Max, not to worried about the connection or eArc. The LSX is a smaller form factor then their other speakers, which is one of the primary reasons I am considering them.
