The Yulong U100 is a high performance, accessibly priced, USB DAC and headphone amplifier. The USB data is received and processed with the high-performance TE7220L (24Bit/96KHz), and the decoded I2S signal sends directly to a Cirrus logic CS4398 (120dB dynamic range, ultra low THD+N at -107dB) for DA conversion. Components in the analog circuit include: ADA4075-2; High-precision Panasonic SMD CBB capacitors and 0.5% SMD resistors. The power amplification is handled by a ADA4075-2 plus a "Diamond" transistor buffer circuit. This simple, efficient and direct coupling mode of the circuit assures that the minimum signal path length, avoiding signal interference and loss during the transmission. This kind of circuit design makes for the best possible sound given available components.
With negotiations come more competitive pricing. The vendor has agreed to drop the final tier, if met, by $30. This means a happier wallet for all. We've extended the drop deadline by 4 days to give the community more time to take advantage of the drop.
The U100 features RCA line out as well as 3.5mm line in, so it can be used as Dedicated USB DAC or a stand alone headphone amplifier via the 3.5mm line input. The power supply of the U100, developed by ShenZhen YuLong Electronics Co.,Ltd, utilized an audio grade, special designed switching power supply with high-performance and very low ripple which assures the U100 has sufficient driving ability and excellent performance in a small size. The U100 has an elegant, compact housing (160*110*30mm) which is carefully made made aluminum alloy only weighing 0.48kg. All in, this is a full featured, well reviewed, DAC and headphone amp you’ll be glad to own.
