E1DA 9038S G3 Susumu Edition DAC Headphone Amplifier with susumu precise 0.1% resistors
The update of 9038S DAC+HPA
The regular update of 9038S DAC+HPA, we&x27;ve named that 9038SG3. Pretty much the same sounding and specs but some major weaknesses of the G2 were improved dramatically.The new 9038S version will have a black sandblasted anodized aluminum case and caps machined with CNC(G2 used laser-cut that&x27;s not too accurate). Logo and the model name are laser marked, an elegant and reliable solution vs G2 silk print. The E1DA 9038s Gen 3 improves on the already beautiful sound output of the Gen 2. It has improved Signal to Noise Ratio, Dynamic range, and THD+N values and provides an ultimate sound quality output with crisp clarity. The output is rich with a dark background completely noise and distortion-free.
New USB audio bridge
The first thing is another USB audio bridge with HW Volume(UAC2->ES9038), 32/384, and DSD256 support. Sure, it&x27;s not a big deal but it remains unknown whether another portable DAC with DSD256 could support for Android, only DSD128. Also, 9038SG3 includes the standby mode to save your phone battery if DAC is idle > 2 minutes. Strongly reduced LTE buzzing noise aka "static", hence 9038SG3 become more and more portable. Slightly improved SNR, Dynamic Range, and THD+N. Due to PCM384 and DSD the frequency response is extended up to 100kHz(10-100000Hz +0.1/-0.3db). The output impedance is 100mohm.
"E1DA Tweak" App on Android Smartphones
The audio modes have been deleted, and by default, only the Performance mode(without any delays/interruptions) remains. Instead, a large amount of hardware ES9038Q2M DAC control is presented, with a new Android "E1DA Tweak" app with the preset manager, harmonics distortions compensation, Nyquist&x27;s filter selection, MasterClock frequency and more, most of these parameters could be dynamical defined depends on HW Volume, of Audio DATA Rate etc. In other words, make your own ES9038Q2M based DAC, and save that as a preset( to share this preset) However, the app release is delayed, thanks to covid19 one more time. The new USB bridge would allow you update 9038SG3 FirmWare by USB, and FW file will be provided to everyone who gonna go to use the app.
The new 9038S version will have a black sandblasted anodized aluminum case and caps machined with CNC(G2 used laser-cut that&x27;s not too accurate). Logo and the model name are laser marked, an elegant and reliable solution vs G2 silk print.
All these improvements have some cost but as usual, 9038SG3 price range would be similar to the predecessor.
Please Note:
Don&x27;t use 2.5mm/3.5mm adapters as that might damage the DAC.
