For the nit-pickers and nerdy ones here, I’m giving the specs and technical sheets. For all the others, you can just go to the next page to see how the DAP performs.
DAC and LPF
The Shanling M6 Pro uses two AKM AK4497EQ, a chip found in a wide variety player or DAC already.
It’s a popular one, found within the FiiO M11 Pro for example or Astell&Kern’s SP1000M. Asahi Kasei issued the chip with Velvet Sound Technology and advertised a 131dB SNR in balanced mode. Also, the Shanling M6 Pro offers full decoding of PCM files up to 32bits/768kHz.
To do so, Shanling implemented two Japanese KDS low phase noise active crystal oscillators, and an FPGA chipset to ensure bit-perfect decoding.
The brand says that each additional component was chosen very carefully :
- white copper shielding on top of the audio circuit,
- four TI OP1662 for low-pas filtering
- four ADA4610-2 + four BUF634 for the balanced output amplification
The capacitors are provided by ELNA and Panasonic, two Japanese firms well-known for the quality of their products., If you can find some of them in high-end gear such as Accuphase, you’ll be glad to know that Shanling kept the four Selmic II capacitors and Tantalum Polymer.
In single-ended mode, separation is announced at 75dB@32ohms. But, in balanced mode, the separation reaches new heights, 109dB@32ohms, a whopping difference. Otherwise, Dynamic range and SNR are quite similar, with a small 1dB variation.
Power output is now rated at 200mW@32ohms in single-ended mode, and triple up to 600mW@32ohms in balanced mode. So, again, I’d strongly suggest that you use the Shanling M6 Pro through its balanced outputs.
