This is a message from China, sorry for my english.
I bought a Linn AV5103 from ebay.
There is no DTS logo on the front panel, also can't find DTS option on OSD manual.
so I guess it's a early non-DTS version.
How can I upgrade it to DTS and lastest software.
I love its sound as a music pre-amp, don't mind it's only 5.1, but I need DTS when I watch movie.
