Know before you buy
The tube output utilizes a NOS GE tube to provide a warmer, more organic sound with added harmonic richness. In contrast, the solid-state output offers a more neutral, transparent, and precise presentation, allowing you to tailor the audio to your specific headphones or musical preference.
Yes, the DPH-1 functions as a full-featured DAC and preamp. You can connect it to an external power amplifier or active speakers using either the tube or solid-state RCA outputs.
The DPH-1 supports PCM audio up to 24-bit/192kHz and is capable of decoding DSD files. It uses an XMOS asynchronous USB input to ensure high-quality data transfer from your computer.
The remote control is primarily designed for convenient volume adjustment. You will need to manually toggle the output selection between tube and solid-state modes on the front panel.
The unit is quite versatile, featuring USB, Coaxial, Optical, and BNC digital inputs. This allows you to connect multiple devices like streamers, CD transports, and computers simultaneously.
The tube buffer is part of a dedicated output path. You choose between the tube-buffered RCA output and the solid-state RCA output via the front panel switch, so you are never forced to use the tube stage if you prefer the solid-state sound.
