“The DDP-1 and DPA-1 bring terrific sound and stunning value to the category. As a linestage, the DDP-1 is amazingly clean and transparent ... The DDP-1’s DAC section is simply sensational; this level of sound quality would be outstanding in a $4000 stand-alone DAC ... Moreover, the amplifiers possess the same level of clarity and resolution as the DDP-1.”
— Robert Harley, The Absolute Sound
