I know the 105 uses Saber 9018 dac chips and the 205 uses Saber's newest and best dac chips. Interesting that you think your older Theta Prime 3 dacs sound equal or better than the 205's. Of course, there's more than just the dac chips used that determines the final sound quality.
But I get your point. Fortunately, I like the sound of my music files using the 105 as the dac. I also notice there's a quieter background, more detail and greater dynamics when playing a Blu-ray disc compared to cable and streaming. I was thinking the video differences may be less discernible to me due to the 105's video processing circuitry.
Thanks,
Tim
