OTL/OCL (Output Transformer-less/Output Capacitor-less) analog output designs to the very best of today’s DAC technology.
In common circuits, output capacitors or output transformers are these two coupling devices also introduce their own influences on the transmission of the musical signal, adding their own character (colouration), increasing distortion, and consuming small signals, all as predicted by physical efficiency theory. In addition, they also limit signal dynamics.
No colouration of the musical signal
Extremely detailed expression, natural harmonics, and subtle musical decay
The lowest possible distortion
The widest musical dynamics
The sound was perfectly clear. The stage was endlessly transparent and clean, like a day completely without dust, smoke, or cloud. I thought, “This is the kind of sound you should hear with an OTL/OCL circuit applied to a vacuum tube DAC!” This is the story of the D-10000 OTL/OCL DAC recently introduced by Korean manufacturer ALLNIC.
“This is the kind of sound you should hear with an OTL/OCL circuit applied to a vacuum tube DAC!”
OTL/OCL (Output Transformer-Less/Output Capacitor-Less) is a circuit that literally removes the transformer of the vacuum tube amplifier output stage and the capacitor in the signal path. The output transformer lowers the high output impedance of the vacuum tube, and the capacitor in the signal path has the heavy duty of blocking DC, so omitting both of them has been a fairy-tale dream for manufacturers.
However, ALLNIC determined that these devices are the main culprits for distortion, coloration, and energy loss, so they spent years developing OTL/OCL circuits for their high-end preamplifiers, the L-10000, L-9000, and L-8500, and the HPA-5000XL headphone amplifier. The results have been a great success. As the output transformer and capacitor disappeared from the signal path, unimaginably pure and fresh sound flowed out like a wave. This is why foreign media praised the ALLNIC OTL/OCL preamplifiers as “Less is so much more”.
“Less is so much more”.

The most eye-catching front panel features are the Conversion (Conv) and Upsample buttons in the middle of the D-10000’s face. When the Conversion button is pressed, the input PCM signal is changed to a DSD signal and the DSD LED illuminates. When the Upsampling button is pressed, the user can select from a range of choices to upsample the PCM input signal all the way to 352/384kHz.
On the top plate, across both sides at the rear, there are separate power transformers for the digital circuits and the analog circuits. The vacuum tubes involved in the converted analog signals are arranged along the middle for each of the left and right channels. From the front, there are two pentode/triode 7258 tubes, two twin-triode 12AU7 tubes, and four 6C19P triodes. The 6C19P has a low internal resistance of just 400Ω, making it ideal for a preamplifier or DAC output.
