MHDT Labs Orchid is a R-2R and tube DAC with tube buffered output.
It uses the legendary Philips TDA 1541A dac as in some very high-end dac many times more than it’s value.
Orchid is capable of up to 24 bits / 192 kHz digital signal inputs with a frequency response of 20 Hz – 20 kHz (+/- 2dB).
It has non over-sampling, no digital filter, no op-amp and no feedback thus resulting a more realistic and natural sound DAC.
The DAC is equipped with GE Jan 5670W 3 mica tube which could last about 6,000 – 8,000 hrs or almost 10 years for 2 hrs playing every day. It also accepts various types of tubes for tube rolling to your satisfaction.
The 4 digital inputs are independent to each other. Only one among them will be active to ensure the best sonic output with minimum noise interference.
Last input is stored after power off for convenient replay.
The DAC also features an asynchronous USB inputs.
