VERDICT

Shanling UA1 Pro. While the older Shanling UA1 was designated as “safe tuned” Dongle, the Pro version took a step ahead and embrace some risks to inject some X factor into it. Which to my ears, sounded so very ESS sounding similar to the likes of HiBy FC3, Audirect BEAM 2SE and Zorloo Ztella. It is markedly brighter, faster and technically more competent than the original UA1.

However staying to native ESS tuning also means this particular dongle will sound metallic and digital-ish especially when paired with Diffused Field Neutral devices like Etymotic ER4SR and VE Duke. Even on my FOSTEX T40RP MK3 it has that ESS upper register shimmer that is dry and unnaturally bright.

What is impressive about this UA1 Pro, driving power seems to have improved doubly compared to the older variant. The normally stubborn T40RP MK3 Magnetic Planar sounded great with wholesome dynamics. I was able to observe well extended dynamic range despite the upper registers sounding a bit artificial. Mid-Bass has enough meat and presence to make it exciting, just Sub-Bass being a bit less audible and practically almost unheard with both the ER4SR and VE Duke.

Things gets a lot better with warmer pairing. SeeAudio Bravery and TForce Yuan Li exhibited a more balanced sound which edge closer to some organic nuances. I was impressed with the Macro and Micro detail capabilities with these two when paired with the UA1 Pro, which to my ears are on par with the higher tiered Dongles I have tested so far.

However, the Cons that bothered me the most was how wide the jump between volume levels even when used with HiBy Music player. Most of the time I was forced to crank down one notch with the Bravery and Yuan Li otherwise they will get shouty and borderline sibilant. This is somewhat disappointing because some ultra compact and budget Dongles like CX-Pro/Abigail/Avani does it better on this aspect. And then ultimately the emphasis on “bright modern sound” as normally exhibited by native ESS tuning which is hard for me to appreciate.

For the entirety of this review I have opted to use the stock settings at High Gain:

      DC05 is a much better unit with more power. That’s why DC05 ranks higher than UA1 Pro

    As an owner of this model, I thought I’d share a few thoughts/details about the filter options. There are two (as limited by the ES9219 architecture), the ‘standard’ Linear Fast, and for the other Shanling went with the fairly rare Apodizing type 2. I find this second option much better suited for most headphone pairings.

    Apodizing type 2 is based on a Minimum Fast filter, so it shares a couple key aspects useful for the UA1 Pro. First, highs are less harsh due to a lack of pre-ringing, making the treble a bit more organic. Secondly, bass is overall a bit stronger and more solid sounding. These two factors, for me, make for a better balanced and more enjoyable listening experience.
    The down side would be a potential for issues with anyone sensitive to phase shifting, as is par for the course with minimum phase filters. Also, Linear Fast might still work better for very warm headphones/iems, i.e. those that already lean towards bass heavy and need some extra sparkle.

    I love when manufacturers give you the ability to play with settings.
