4. xDuoo XD05 PLUS2<\/h3>\n\n- Pros \u2013\u00a0high power, built-in battery, Asahi Kasei chip, Bluetooth with LDAC support and aptX HD<\/li>\n
- Cons \u2013\u00a0one 6.35mm jack<\/li>\n
- Verdict \u2013\u00a0quite an affordable amplifier that can drive any headphones<\/li>\n<\/ul>\n
The main advantage of the model is a powerful built-in amplifier capable of delivering up to 1,200 mW to a 32-ohm load, which allows you to connect even quite difficult-to-drive headphones to it.\u00a0The digital-to-analog converter is based on the AK4493SEQ chip from Asahi Kasei and is capable of working with PCM signals up to 32 bit \/ 384 kHz, as well as native DSD256 stream and MQA files.\u00a0The model has a built-in equalizer with preset curves for different genres, and support for two USB protocols (UAC1.0 and UAC2.0) allows you to use the new product with Nintendo Switch, PlayStation and Xbox game consoles.\u00a0The 5,000 mAh battery provides up to 9 hours of continuous music playback.<\/p>\n

3. Shanling H5<\/h3>\n\n- Pros \u2013\u00a0sufficient power, DSD 512 support, memory card slot<\/li>\n
- Cons –\u00a0the price is already felt…<\/li>\n
- Verdict \u2013\u00a0a beautiful DAC with a powerful amplifier<\/li>\n<\/ul>\n
In this model, the DAC unit is built on a dual AK4493SEQ chip and can work with a 32-bit \/ 768 kHz PCM signal and a DSD 512 stream; 6 user-switchable filters are provided.\u00a0A USB-C port or a 3.5 mm jack is used to supply a digital signal; for wireless connection there is a Bluetooth adapter with support for the LDAC codec.\u00a0The amplifier produces up to 227 mW into 32 ohms when connected to a 3.5 mm jack and up to 840 mW into 32 ohms when connected to a balanced 4.4 mm jack.\u00a0On the top panel there is a volume control knob and a wheel for navigating the menu, below them there is an OLED display measuring 0.87 inches.<\/p>\n

2. Quloos MUB1<\/h3>\n\n- Pros –\u00a0powerful amplifier on BUF634, digital signal output, four chips in the DAC<\/li>\n
- Cons – a little\u00a0expensive<\/li>\n
- Verdict \u2013\u00a0an interesting model with a good digital part<\/li>\n<\/ul>\n
The DAC unit here uses four CS43131 chips from Cirrus Logic, which provides a signal-to-noise ratio of -132 dB and a THD of only 0.0001%.\u00a0The amplifier section is made of four BUF634 op-amps, the output power is up to 1,100 MW at 32 Ohms.\u00a0There are two jacks for connecting headphones \u2013 3.5 mm and 4.4 mm; another 3.5 mm jack can be used to output a digital signal in optical or electrical format, as well as a linear analog signal.\u00a0The Bluetooth adapter supports LDAC and aptX HD codecs, and there is an OLED display on the front panel of the aluminum case.\u00a0The device can work with PCM signals up to 32 bit \/ 384 kHz and native DSD256, the USB-C port supports two operating modes – UAC2.0 and UAC1.0.<\/p>\n

1. iFi Audio iDSD Diablo-X<\/h3>\n\n- Pros –\u00a0incredible power, high-quality components, linear output<\/li>\n
- Cons \u2013\u00a0price, USB-A connection, no 3.5 mm jack<\/li>\n
- Verdict \u2013\u00a0a uniquely powerful portable model<\/li>\n<\/ul>\n
The most powerful and expensive device in our rating is housed in a case measuring 166 x 72 x 25 mm and weighs 330 grams.\u00a0The DAC block in the model is built on a Burr-Brown chip, the analog part includes OV2627 operational amplifiers, OS-CON and Panasonic ECPU capacitors.\u00a0To supply a digital signal, which is quite unusual for a portable DAC, a USB-A port is used, as well as a 3.5 mm jack capable of receiving an SPDIF signal in electrical and optical format.\u00a0The analog linear output is organized on a balanced 4.4 mm jack; 4.4 mm and 6.35 mm jacks are provided for connecting headphones.\u00a0One of the main features is the presence of a special X mode, intended for use of the device with xMEMS headphones operating on the piezoelectric principle.\u00a0The model’s output power is 611 mW into 300 ohms and an impressive 4,980 mW into 32 ohms.<\/p>\n","protected":false},"excerpt":{"rendered":"
