Our take
The XQ-20 is not your average entry level portable headphone/ earphone amplifier. xDuoo XQ-20's biggest selling point is to retain the source's sound signature with a mild touch of being on the warmer side. Delivers an engaging sound and low-end bass impact by providing additional power which non-audio dedicated devices needs. Highly recommended for someone looking to start their audiophile journey!
Product details
XQ-20 is a dedicated headphone amplifier, from xDuoo, a HiFi company based in Shenzhen. The xDuoo XQ-20 utilizes ALPS potentiometers from Japan along with Nikon and ELNA capacitors with an OP (OPA1652) + BUF (LMH6643) circuit architecture from Texas Instruments (TI).
The chassis is made of durable CNC-machined aluminum alloy, sandblasted matte black finish with rounded edges and complete with a two-setting bass boost and gain switch conveniently located on the side.
Ideal for pairing with a smartphone or digital audio player when you’re on the go, the XQ-20 headphone amp measures a measly 1 centimetre thick and weighs just 85 grams. It aims to improve the source it’s paired with in terms of music dynamics, sound-stage, and bass extension.
