Features:

● Shielded transformer with a unique character of an isolator, which filters out high frequency noises

● Dop64 and Dop128 supported through SPDIF, Optical and AES.

● PCM 24bit 384KHz supported through SPDIF, Optical and AES.

● DoP64, DoP128,Native DSD64, 128, 256, and PCM 16-32bit, 32-384 KHz are supported via USB.

● Fully balanced decoder topology.

● Fully balanced high current preamplifier.

● Fully balanced headphone amplifier with TPA6120A2.Less than 4.7 ohm special output

● AK4497 DAC with low noise regulator at reference voltage and analogue supply.

● OPA1611 with ultralow distortion for LPF and high current OPA1688 for output buffer.

● Ultra-Low jitter PLLclock.

● Highly user customizable digital filter.

● Customizable sound mode.

● 99 steps volume control to pair with headphones in different impedance and sensitivity.

● Elegant front panel and aluminum housing. Unique claw-style suspension feet.

● Universal 110-240V mains power.

Yulong has a reputation for producing highly regarded all-in-one units, like the DA9 and the DA8. Now, the company aims to deliver the highest sound quality from a more compact all-in-one package. Introducing the Aquila: a balanced DAC/amp with all the inputs and outputs you could ask for, including USB, S/PDIF, and Toslink, plus RCA and outputs for dual-3pin XLR for driving studio monitors. The front panel has a standard 3.5-millimeter jack and a 4-pin XLR jack for driving balanced headphones. Using the balanced out, you’ll get significantly more power: 1.5 watts at 32 ohms, for example. The Aquila also offers a few unique sound modes. Mode 1 is balanced, mode 2 is great for classical music, and mode 3 emphasizes a strong voice presence, ideal for jazz vocals.

YuLong have just announced a new flagship model, the DA10, I have been using the DAART Aquila a lot with my HE-500, along with using it as a pre-amp with the Burson Bang and it is really clean. It also works really well with IEM's surprisingly, so I expect the DA10 to be excellent with more power and a better layout.

DA10 and DA9 have the same DAC chip AKM4497 and headphone amp modules. DA10 add FPGA module which is very common in the hi-end DACs. It's a big improvement.

I haven't tried the DA9, but a lot of their designs are very similar but have small differences that make big changes. I think the Yulong devices are very solid and I enjoy the DA10 a lot.

I would like to share the latest officical firmware of Yulong DA10 with you. Just follow the Readme.txe to update your DA10 firmware.

I've updated the firmware as I found it on another site, and it made the volume control steps much better on my device (it used to sometimes jump 2 steps with one click). I can't really detect much of a sound difference, but I didn't listen back to back.

Does anyone know whether the digital filters built in are minimum or linear phase?
