The presentation is fairly sober, with no fuss, and the size of the box and device are proportionate. The accessories aren't many, but among them is the clip-on case, which is a perfect fit, even if it's not the prettiest or sturdiest piece to go with the sleek S9 Pro. On the other side of the scale, there's the USB cable, which is the same as previous products and is still no better in terms of stiffness and memory effect. I would recommend a better cable, with higher quality, cross-section and manageability. Perhaps a braided cable would be a better option. Improvements from sources are primarily minor and nuanced, despite my textual descriptions. If you are beginning your head-fi journey, getting different IEMs or earphones would yield more benefits. If you know your gears very well, improvements from sources can be delightful During operation, it should be noted that the body, especially on the glazed sides, becomes a little warm, especially when the volume is increased. In a low voltage regime the temperature is not bothersome. But taken to the limit, as when I took the measurements, i.e. at full power, the heat reached by the device is high, even worrying. I assume that, even so, it is within the "normal" operating range, without suffering any damage. Tested on Mi 13T(Mediatek Dimensity 8200 Ultra) Poco F5 (Snapdragon 7 Gen 2), Asus Zenfone 10 (Snapdragon 8 Gen 2), ROG Phone 7 (Snapdragon 8 Gen 2), Galaxy S23 FE (Exynos 2200) The S9 Pro is smaller than I expected it to be, which is good. After seeing photos online, I expected it to be larger than it actually is, which is still bigger than something like the Apple Dongle but is small enough to store in an IEM case quite easily.
Technicality wise, the Dawn Pro is close to the S9 Pro Plus, I have to give an edge to the S9 Pro Plus Martha on the Imaging department, thanks to its more proper weight sound.Martha has been chilled at this impedance by BAL, giving values lower than the SE output: 1V, 69mW and 68mA. The S9 Pro is a narrow and elongated piece, measuring 59x18x8mm, made of a high-density aluminium body. The larger sides are glazed. On the top one, there is the Hidizs logo and an LED, located at the bottom, near the USB connector. On the lower side is the Hi-Res logo and a description of the device, in small gold letters. This review is based on a review sample provided by Hidizs (Thank you!) I have no financial interest in Hidizs or the success of this product. Moreover, the S9 PRO Copper Limited Edition boasts some impressive measurements under the hood (Total harmonic distortion), at 0.0006%@32ohms in the 3.5mm out, and 0.0012%@32ohms. The S9 PRO Copper Limited Edition comes in a professional cardboard box with an image of the S9 Pro Copper Edition adorning the top lid with a glossy finish.
There are only 3 inputs and outputs present; a USB-C connector at the rear of the unit, and a 2.5mm balanced and 3.5mm output right below at the other end. Controls In honor of this magnificent species, which disappeared 109 years ago, Hidizs, a professional audio brand, named its third-generation S9 Pro Plus HiFi Balanced Dongle DAC after Martha. The S9 Pro Plus has arrived a few years after the S9 Pro and I think it is a worthy upgrade to the previous model. The S9 Pro was (is) a very good dongle but, in my opinion, it was just a little harsh in its presentation.The S9 PRO Copper Limited Edition shares an identical form factor to the S9 Pro. Structurally, there are no observable changes, and it still retains the S9 Pro’s distinctly monolithic appearance.
It depends, what is your device you're gonna plug the S9 Pro Plus Martha to, and do you need an independent volume control or not.Red Light” Linear phase fast roll-off: Enhanced analytical capabilities, delivering a clean and crisp sound.
Without going into sound preferences, basically I just wanted something as clean and detailed as possible, while being as small and compact as possible. I also wanted something that I could plug into my DAP to be able to have the same sound reference without being tied to my phone or tablet, more on that in a moment. Its power is fine for almost all headphones and iems , however compared to other dacs in my possession it definitely has more juice. However, speed and tactility are its fundamental strengths; users’ mileage may vary. For example, acoustic recordings featuring even-harmonic warmth appear are weakened by marginally exasperated treble.
Since the Audirect Atom 2 and the S9 PRO are both sitting on my desk, much of my listening was done as a direct comparison between the two. I primarily conducted my evaluation with the new gold colorway 1MORE Triple Driver over-ear headphones.
