Topping D30Pro 4X CS43198 DAC

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 R and XLR have reached the 1 20dB SINAD So that R transmission can also have same excellent performance as XLR.

5.A30Pro will be the best partner for D30Pro: 2x6W@ 1 6ohm 2x5.5W@32ohm2x840mW @300ohmso there is no headphone that A30Pro can't drive well. New specifically redesigned NF module provide THD+N<0 .00006% and <0.3uV noise.
