I used the Sangean with the Logitech (Slim Devices) Transporter as a DAC but did not hear any real improvement over the Sangean built-in DAC. HD radio has a low bit rate; I suspect that is the limiting factor. YMMV. Good luck!
Sangean HD Tuner used with external DAC
Anyone try the Sangean HDT-1x digital HD tuner with an external DAC? I am thinking this might improve sound quality but don't want to purchase a DAC unless it helps quality. Thanks for the view and your opinions.
