DHTs do not merely amplify the signal from indirectly heated triode stages. The A- 5000 DHT, L-5000 DHT, and H-5000 DHT amplifier, preamplifier and phono-preamplifier are pure DHT, from signal input to output; and now, Allnic has produced the: ALLNIC AUDIO D-5000 DHT DAC, WITH A PURE DHT ANALOG OUTPUT SIGNAL PATH. _________________________________________________________________________________...
OVERCOMING THE DIFFICULTIES OF PURE DHT AMPLIFICATION DESIGN • Rarity of DHT tubes suitable for small signal amplification The essential DHT tubes for small signal amplification should have high gain, low internal resistance and high mutual conductance. It is extremely difficult to make that kind of DHT tube. Among hundreds of kinds of DHT tubes, it is difficult to identify those that are best for the specific characteristics required for the particular amplification challenge.
It is also intended to provide an I2S input in the near future. This separate system will be connected to the D-5000 DHT DAC by a proprietary method through the AES port. The I2S system will provide not only PCM but also DSD and have the capability to support extreme up-sampling and cross conversion between DSD and PCM.
We advise that you keep the box and other packing materials that your D-5000 DHT DAC came in. They will be useful if you sell your D-5000 DHT, or in the unlikely event you need to ship the unit for service.

• Two (2) coaxial digital To select the input you want to play, rotate the knob on the right of the D-5000 DHT’s front panel clockwise and counter-clockwise, (See Figure 1) or use the appropriate part of the remote control (See Figure 4 and the section “The Remote Control”...
• turned the volume down or muted your preamplifier To turn on the D-5000 DHT, press in the rocker switch on the left side panel near the front of the unit and marked with on and off icons. To turn on the D-5000 DHT, press the top of the rocker switch in.

DSD Playback and “CONV” (Conversion to DSD) In the case of playback of a native DSD signal from the source, the D-5000 DHT employs DSD over PCM (“DOP”). The user should set up the source software to output for the DOP standard.

NOTE: While the D-5000 DHT DAC is run in and tested at the factory, users have reported that the sound improves steadily through the first two to three hundred hours of use.

D-5000 remote control. If you need to use an Apple device at the same time as you are using the D-5000 DHT and cannot move your Apple device out of range of the D- 5000 remote control, you should be able to disable the remote control sensor of the Apple device in the device’s System Preferences.
