This pack will allow you to enjoy an audio system composed of a Topping A30 Pro headphone amplifier and a Topping D30 Pro DAC, both of which are extremely high-performance, for rich, accurate and immersive listening. An XLR cable is also included, allowing you to connect the devices in a balanced way.

Model: D30 PRO
Features:
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, 2×5.5W@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.
