Model: D30 PRO
1. Preamplifier function: D30Pro has preamplifier function so you can control the output volume on the front panel and also at the remote control. Since it's noise is <0.9uVrms@SE out and <1. 1uVrms@BAL out, which is significantly lower than other similar products, it is very suitable for connecting to power amplifiers or monitor speakers. And this will also help you leave the budget of a preamplifier.
2. CPLD focusing on clock processing and digital signal optimization, restoring what the digital signal should be.
3. We use up to 8 independent LDOs to supply power to different loads, SO there is no longer interference between different loads.
4. Both RCA and XLR have reached the 1 20dB SINAD, So that RCA transmission can also have same excellent performance as XLR.
5.A30Pro will be the best partner for D30Pro: 2x6W@ 1 6ohm, 2x5.5W@32ohm,2x840mW @300ohm,so there is no headphone that A30Pro can't drive well. New specifically redesigned NFCA module provide THD+N<0 .00006% and <0.3uV noise.

APX555B limited our measurement again
The THD+N of A30Pro is no higher than 0.00006%，which means the A30Pro accurately restores 99. 9994% of the
original sound, what you get is what you input. Because noise of A30Pro is low enough, so APX555B limits the noise
measurement of it, resulting in the need to amplify the noise of A30Pro by 100 times for indirect measurement.
4PIN XLR+4.4mm+6.35mm output
Since then, buying headphones does not have to consider whether the plug matches the headphone amplifier,
because the A30Pro already provides you all in a compact body, including 4-PIN-XLR，4.4mm，6.35mm.
SE + BAL input pass through
When shutting down, the input signal is directly output to RCA or TRS without amplification,
which will be more suitable for active speakers/monitor speakers when the DAC has pre-amplifier functions.
Even better is when used with D30Pro, the excellent noise performance of D30Pro is not wasted.
