Connectivity​It should be noted tha The rendition of the sound is same like its midrange, it demands attention and very lively, “here, listen to this cymbal, crashes and hi hat !” The ES9038Q2M is a powerhouse that supports high-resolution audio. With a maximum 32-bit/768kHz PCM sampling rate, it delivers unprecedented precision. This level of detail captures even the subtlest nuances in music, guaranteeing a pristine audio reproduction. The chip boasts an impressive Signal-to-Noise Ratio (SNR) of up to 128dB and an astonishingly low Total Harmonic Distortion plus Noise (THD+N) of -120dB. These figures define audiophile-grade audio quality. And the best part? This technology isn't limited to high-end audio systems but extends to portable devices, setting a new standard for audio quality.

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. I am actually a happy user of the Apple Dongle, it has proven to be of very good quality for its price (which is why I have ended up with multiple units) but there are a few situations in which the tiny device just can’t cut it. This is mainly with over ear headphones, which I rarely use away from my desktop devices anyway, but there are also some IEMs that benefit from having a little more power, especially if we consider the fact that the EU version of the Apple Dongle is only half as powerful as the US version. The Creative DAC is certainly a powerful beast and for what it costs it offers exactly everything you need with much higher support (firmware updates + Apps). Its sound is definitely different from the classic AK4377 but you feel that Creative’s experience has added something enjoyable to the sound. Independent volume is a plus! The SFXi however is very light and robust! Ideal for portability!

FEATURES​

As I mentioned that S9 Pro has some reference-neutral characteristics, it has some emphasis on treble region that gives that analytical, dry and airy sound at the expense of being too lean but S9 Pro doesn't even sound lean and inadequate. I like the S9 Pro, it meets my criteria and does exactly what I wanted it to, but I am not in love with it.
