Alpha Design Labs by Furutech ADL-H118 headphones and X1 portable headphone amp
Meanwhile, ADL’s X1 fits in the palm of a hand and combines headphone amplifier with ESS Sabre ES9023 USB DAC. The X1 supports iOs and Android operating systems at resolutions up to 16-bit/48kHz via its USB A socket, while its USB Mini-B socket and 3.5mm optical output (the latter making the X1 compatible with a dedicated hi-fi) are said to handle all resolutions up to 24-bit/192kHz.
Listening to James Blake’s “Limit to Your Love,” I heard a very natural bass sound and dead silent backgrounds. The X1 will be available in metallic white, silver, blue, black, and red finishes, and will cost around $550. Look for it this March.
