HiBy FC5 MQA. For some reasons HiBy opted to stick with ES9281 series of DAC chip, similar to the older model of FC3. With an exception now the redesigned the whole setup to accommodate dedicated Amp modules of ES9603 (dual). From certain perspective I can totally understand why they opted to remain with the same DAC chip, ES9281 is still among the best out there with native MQA support, also considering that HiBy would already be well versed with a DAC chip that has been successful to them. As opposed to trying out different chips that may require new learning curve. As it is, it is evident to me this resulted in a very matured sounding unit that is clearly a much-improved unit over the old FC3. The FC3, while being a decent Dongle by itself, does have some cons that I find detriment to overall listening enjoyment, highly technical yet overly bright. FC3 was a unit very raw with ESS glare and brightness, being great only when paired with warm sounding listening devices. Thankfully, the FC5 does not have this raw ESS sound anymore. What I am hearing is a beautifully clean sounding unit that is truthfully neutral and well balanced throughout the dynamic range.
One aspect that pleases me the most is how powerful this FC5 is. Unlike the FC3 which has some limitations with highly demanding IEMs/Headphones/Earbuds, the FC5 exhibited amazing driving capabilities even with my Fostex T40RP MK3, a magnetic planar headphone that is notoriously known to be among the hardest to drive at 91db of sensitivity. The mark of proper synergy is a sound output which is effortless and liquid smooth, no hint of strain anywhere. The T40RP sounded at home with FC5, Bass being rich and deeply extended, Treble with similar traits. Mids being very transparent and engaging. This is consistent with the rest of my “hard to drive” equipment, the Etymotic ER4SR, VE ZEN 2.0 SLQ (320 Ohm) and VE Asura 2.0 FE (155 Ohm).
On the other end of the spectrum, FC5 exhibited amazing prowess working with highly sensitive IEMs like the CCA CA16 Pro (which is notoriously prone to hissing and noise). My CA16 Pro sounded super clean with black background. Similar results for the likes of TIN HiFi T3 Plus and KZ ZEX Pro.
Another element worth mentioning is the soundstage. The width, depth and height are so very unlike a typical ESS based DAC. HiBy must be commended for this feat. Comparing against another of my favourite ESS 9281 Dongle, the Questyle M12, same thing observed with Hidizs S9 Pro and E1DA 9038SG3, all exhibiting tall but narrow staging. It is evident to me FC5 has better width and space. Both comparatively tall. However, I must admit that the THX Onyx remained the undisputed champion on soundstage width and expanse among all #donglemadness contestants.
On the subject of MQA, FC5 delivers. Now from my own experience with Tidal Masters, some ES9281 dongles may exhibit crackling artifacts with some songs. But with FC5, after some extensive testing I did not encounter a single occurrence of this happening. So, I am assuredly very happy with that.
Last but not least, despite being primarily a 4.4mm Balanced unit, FC4 came included with a beautifully made 3.5mm SE adapter that will allow for usage of normal stereo plugs. Now, through my own observation the quality variance is not audibly apparent be it BAL or SE. Perhaps the actual power delivery could be less with the SE, and this will work perfectly with easy to drive IEMs. However, for more demanding ones, it is best to use the 4.4mm BAL to ensure full might of the 2 Vrms driving power.
Ultimately, what clicks for me is the overall tuning of FC5. This time HiBy hitting it right with balance and neutrality albeit not being as analogue/organic as how I normally prefer. No offensive brightness or coloration of Mids and Bass. Also, FC5 can synergize with practically anything. From serving as AUX feed for Shure KSE1500, highly sensitive IEMs and Hybrids or something outright demanding, FC5 does it all with great finesse and articulation. A true winner in my book.
- I would like to thank HifiGo for providing me this unit. HifiGo has been very helpful with #donglemadness since the very beginning, offering me generous discounts due to my repeated purchases in large numbers.
Best Pairing: Flexible practically with anything.
