Luxury & Precision W2. This is a flagship DAC/Amp Dongle designed from the ground up destined to be a fine bespoke specimen. Everything about it shouts quality and precision. Simply beautiful. There’s a wealth of options that will make any mid-tiered DAP blush. SPDIF, EQ, Filters, Gain Selection etc. Not forgetting the intricate power circuitry that individually serve the dual CS DACs and Amp stage. This is a micro DAP any which way I looked at it. The sound is utterly natural and neutral with great fidelity that is definitely reference grade. W2 is an upgrade over Lotoo PAW S1 assuredly, PAW S1 losing it by being a bit more laid back and lean sounding in contrast. Compared to Astell & Kern PEE51, W2 made PEE51 seemingly colored with that super euphonic signature and energetic timbre. But then I don’t really see this as being a negative as they are meant to cater for different tastes and varying synergies. There’s no right or wrong.
W2 passed the FOSTEX T40RP MK3 91db Magnetic Planar brutal test (Balanced, High Gain) . It does need the volume to be cranked all the way to 75-80/100. But once desired loudness has been set, the output is great. However it is not as meaty and wholesome as how it was with Ovidius B1, Hidizs S9, S9 Pro and hiliDAC Audirect BEAM 2S. While fidelity is great and refined, vibrancy was mildly laid back compared to the other 4 top performers. Timbre coherence and stability is top notch, devoid of any signs of distortion or jitters even subjected to very heavy load. This is a great option for those preferring smooth neutral output from their planars.
Etymotic ER4SR (Balanced, High Gain). My favorite BA sounded truly Hi-Fi with W2. That polished smoothness complementing ER4SR technical characteristics exceedingly well. The best part, despite being highly resolving, both the source and IEM does not sound sterile and dry as how I heard it when paired with some ESS or Cirrus based DACs (HiBy FC3, Hidizs S3 Pro, Zorloo Ztella, JM20, Cayin N6ii E02, Topping D10s). W2 was able to strike a true neutral output with ER4SR to make any Diffused Field Sound fans proud.
VE Asura 2.0 (Balanced, High Gain) on the other hand is almost like a contrast to the performance exhibited by ER4SR. While both being highly technical and fast, audibly the overall tone is warmer on the Asura especially with very lush and rich mids. I can literally feel Diana Krall’s sexy voice engulfing me with velvety sensation. This is a super combo to enjoy Mids focused presentation. It is just breathtaking, silky smooth yet still very technical and with agility. W2 and Asura does seem to be a match made in heaven.
Moondrop Aria & HZSOUND Heart Mirror (Single Ended, High Gain, FAST Filter). I was taken aback by what I heard from Aria. Bass responses were audibly slow despite being well controlled and textured. This may appeal to those who prefer their Bass indulgence slow-cooked, but not me. The rest of the spectrum are just okay-ish, I have heard the best performance of Aria when paired with Zorloo Ztella. Similarly the normally fast and sparkly Heart Mirror exhibited mildly subdued output. There’s smoothness and refinement but I have heard better from Heart Mirror paired with a dozen other Dongles. If I am to draw conclusions on this, I think W2 is not as highly optimized for Single Ended use because the Balanced Port definitely sounds a lot better to my ears. And all these were done with the fastest filter profile available for W2.

In addition to my own tests, I decided to extend it further and asked the help of two members from ChiFi Audio Reviews FB group. Edmund Chan and Syazwan. Edmund being a seasoned Audiophile highly respected in the Malaysian Audio scene, He is a crew of AudioMonsta Malaysia. Syazwan on the other hand, is a freshly made Audiophile and I opted to ask him to share his impressions as well. This way I am able to gauge the perspective from both end of the spectrum = seasoned and fresh perspective.
Luxury & Precision W2 is undoubtedly a stellar performer. The sound is well within reference grade quality. However to fully enjoy W2, it is a must to use the Balanced 4.4mm port. I am not impressed with the subdued performance of the Single Ended option.
Best Pairing: Flexible for anything with no less than 91db of sensitivity.
