Inputs ..................................................................................................RCA / XLR
The amp is made in an aluminum case, it feels sturdy and beefy. The front of the amp has a mirror front and the volume controller has a dual function (volume and selector). When you press a few seconds on it , it powers ON / OFF. The amps also comes with a remote control. Bluetooth specification...................................................................................5.0 Build quality is definitely a step up vs some smaller/cheaper Aiyimas I've been messing with lately. Well, at least fit and finish - I can't comment on the internals. This is my second amp based on this chip. I had already reviewed a fully symmetrical dual Mono MA12070 that I had built a few months ago. Picture of the setup attached. Hardly an acoustic paradise down here, but at least the Snells make everything sound fun.Weight ..........................................................................................3.3kg/7.28lbs All aluminum alloy CNC processing technology, using anodizing technology, fine workmanship, first-class touch; As we end off Part II with a detailed look at PCM fidelity, I can say that from an objective fidelity perspective, basically what I'm seeing is an ESS ES9038PRO-based DAC that's performing on par with the best devices available today as published here and on other audiophile objective measurement sources. The XLR 4.77Vrms output is clean with dynamic range of 130dB and 0dBFS THD+N better than -123dB. In a similar way, the RCA 2.35Vrms unbalanced output gives us an excellent THD+N of -120dB. On my more complex Triple-Tone signal, I'm seeing a TD+N of -118dB through the XLR and -111dB through the RCA which are again excellent. A large number of audiophile-grade audio components are used to enhance the subjective sense of hearing;
THD+N ................................................................................................0.0008% I'm running it right now on my "test bench" (aka in the garage) before I move it inside. I'm connected to some Snell K/IIs I keep down here for just such an occasion. Standby power consumption.........................................................................<0.5W USB compatibility ..................................Windows 7 / 8 / 8.1 / 11(Needs Driver) Mac OSX、Linux(Driverless)Channel separation .....................................................................................90dB bits resolution is really not much to ask of modern DACs these days and the graphs basically look like they're layered on top of each other with minuscule variations. Notice that the only mentionable difference is that DACs do have slight frequency response variations, but even this is less than 1dB difference up at 20kHz (and often this is a reflection of the filter selected).
AAC ..............................................................................16bit/44.1 kHz_320kbps I listened to the amp with my favorite Audiophile Playlist for 1 hour yesterday, it is really impressive @ first listening. Seems promising in relation to its ration performance / price. Channel separation ...................................................................................108dB aptX .............................................................................16bit/44.1 kHz_352kbpsYou have the possibility to adjust the bass / treble, the amp also has some presets, I'm not a fan of it, I left it in "direct" mode. Size ...........................................................................280x63x260mm (WxHxD) SNR ..........................................................................................................103dB USB transmission ....................................................................Asynchronization I'm running in bluetooth right now, just because I don't want to haul too much stuff down here tonight. Connecting was easy/normal w my Samsung phone. Unfortunately this phone doesn't do Aptx HD, so I can't test that.
The color display screen and user-friendly operating system are easy to understand, equipped with full-function remote control function; Using the latest DSP chip with ST high-power amplifier chip, carefully designed and debugged, its distortion is as low as 0.0008%;
Subwoofer output
Subwoofer output level..............................................................................2Vrms Overall, this is a phenomenal performance level for a modern PCM DAC for both RCA and XLR line-level outputs.
Great Deal
