Udigital 5.1-Channel RCA Digital Audio Decoder USB Multi-Media Player

This converter works great! It has good quality sound and works as advertised. I am using it to hook into tube preamplifiers which sounds amazing! There is a setup menu however it is not a supported resolution on my 4K tv. It does make clicking sounds from the converting process however this may be my cable. It's a 10-12 year old monster optical cable.

Works great, if you need one get it you won't be disappointed with the quality!
