I have been exclusively using DSD upsample through Roon/HQPlayer for the last 4 years. I was upsampling everything to DSD 512 through my T+A DAC8 DSD. It took the sound quality of my rig to new heights!! However, when I decided to simplify my system to Lyngdorf TDAI 2170, I was very skeptical of giving up the DSD512 upsample.
But anyway, after prioritizing simplicity I went with the 2170. Now I can only upsample to DSD128. I can clearly hear a significant difference between playing pure PCM vs upsample to DSD128. I know Lyngdorf converts everything to 24/96 internally. But it must be so transparent. I wish 3400 supports DSD too, especially in higher bit rate DSD. Also, if the streamer on 3400 doesn't support DSD, there's no point of using that streamer (for me).
