Yes, but in balanced output only. Not enough juice single-ended.

That's for sure, the HEDDphone is rated at 87 dB SPL for 1 mW , that's requires 10 times more power than headphones rated at 97dB SPL for 1 mW, that a very difficult load for single-ended even for full size desktop headphone amplifier.

I have owned the YULONG DA-ART Aquila II for a couple weeks now and couldn't be more pleased with it based on my requirements of high quality sound in a bedside headphone only station. I have a dozen different headphone models to choose so it it came down to which pair was comfortable to lay on a pillow while wearing. The Hifiman Arya wins out for now. Music stored as FLAC resides on a 120TB rack-mounted file server running unRaid (Plex etc as well). Dedicated Roon ROCK on an Intel i7 NUC.

Equipment left to right, top to bottom
Allo USBridge Signature Player (Roon endpoint), iFi nano iGalvanic3.0, YULONG DA-ART Aquila II
Furman AC-215A Compact Power Conditioner, Allo Shanti Dual Linear Ultra Low Noise PSU

VR headset stand used for headphones. Samsung Galaxy Tab S5e for Roon remote.

Sounds exceptional using Roon. Even more so using Roon's built-in DSP function (runs on the ROCK rather than the client) to feed the Yulong Aquila II a high quality music stream.

Thank you so much for your impression. We are excited to have users sharing their first hand experience. This is devil-grade bedside system, its look simple but you pay a lot of attention to find tune the system.

You use ROON to convert the 16Bit/44.1kHz FLAC to 32Bit/768kHz before feeding into Aquila II? So you really have maximized the Aquila II. We didn't test Aquila II with ROON officially, looks like it is fully compatible and maybe we should send an unit to ROON and test for the ROON ready status.

By the way, you have selected an open-back headphone for bedside application? For those who need to share their bedroom with a partner, maybe a closed-back works better, any suggestion to Aquali II users on close back headphone?

The Allo USBridge Signature Player acts as the Roon endpoint. Then the Allo acts as a USB input to the Aquila II. The Aquila II isn't aware of the Roon involvement, it just sees the music signal coming in via USB from the Allo.

As for open vs closed headphones in the bed, its a non issue for me as I sleep alone. I don't really have a suggestion for a closed back as I prefer open. Maybe a nice IEM to take advantage of that 4.4mm balanced output? :)

Certainly agree that open back is the way to go if we don't need to worry about isolation. Wander what other headphones have you tried with Aquila II in your setup?

I'd also enjoy having a chance to hear and review this all in one, I've got mostly the same system except I'm running a Mjolnir Audio CCS Modded SRM 007tA and a Stax 009, I rather enjoy it for DAC reviews. An I've got an Ether CX as well that I enjoy on a lot of solid state amplifiers in addition to my HD 800 that I've had now for a while.

RME ADi-2 is still in the home as well for comparison.

I am interested in reviewing the DA-ART Aquila II.
I live in Warrensburg, MO, USA
I will use the Aquila II with my Audeze LCD-3, ZMF Eikon and Empire Ears Legend X, and possibly the Noble Sultan/Fir Audio M5 if still on hand. Hooked to my MBP and Shanling M6 Pro as well as Cayin N6ii should suffice.
Comparisons to my iFi Pro iDSD, XDuoo TA-30 and Little Dot mk3 se should help, as well as various specialty cables.

My blog (which sees the same reviews as HeadFi) is: https://ngoshawksounds.blog/

Thank you, Andy!

Hello and good morning everyone. I'd like to throw my name in the hat, if I may, for I'd really like to try out this beauty.

  1. The city and country you are located. Concord, NC. USA
  2. Audio equipment that you will be used in your DA-ART Aquila II audition. Oppo PM-1, Sennheiser HD-650 & 660S, Empire Ears Hermes VI
  3. Your current or previously owned DAC, headphone amplifier and headphones (if not listed in signature or HeadFi profile). They should be listed in my profile but I'll gladly supply the list (fairly long) if not.
  4. Reviews on Audio products. I've done several reviews over the years. Each of which can be found on my YouTube channel with their corresponding written review linked in the respective description.
Naturally, I agree to the terms set forth by the tour. Additionally, I sincerely appreciate the opportunity provided for us to experience this rather impressive piece of equipment.
