Hello,

I have recently, connected my Sony TV (Model: Bravia, KDL-46W4100) to the RegaDac, via the Optical Output of the TV. I also have a pair of good-quality Audio Research RCA cables.

I was wondering which type of connection must gives a better quality sound technically? Using the RCA cables to connect the TV to my amp or using an optical cable to connect the TV to the RegaDac 

(The DAC is connected to the amp...)

I really appreciate any help. 

Thanks.
