IKKO Audio (IKKO Technology Co. Limited) is a relatively new Chinese brand that designs & develops Hi-Fi components like In-Ear Monitors and DAC/AMP etc. The IKKO ITM05 is an ultra-portable balanced headphone amplifier and DAC combo, integrating high-quality components in an extremely compact and lightweight format. It's the perfect companion for your smartphone to give you the best sound experience wherever you are. Practical, it slips easily into a pocket or bag. Uncompromising design While IKKO has designed its ITM05 to result in a compact format that fits in a pocket, no concessions have been made on the selected components and architecture to ensure high performance. Thus, the symmetrical digital/analogue conversion stage includes a pair of Cirrus Logic CS43198 DAC chips, each managing one channel, ensuring great sound accuracy while considerably limiting power consumption. ITM05 measurements are therefore particularly good, with a THD at 0.0008% and an SNR at 122dB. In addition, it is capable of reading high-resolution files up to PCM 32bit 384kHz and DSD256. Perfect compatibility The ITM05 offers full compatibility with your favourite playback devices. The input is a USB Type-C or Lightning port and the output is an unbalanced 3.5mm jack or balanced 2.5mm jack. It can accompany an Android or iOS smartphone, a computer running Windows or Mac OS and will connect to balanced headphones as well as regular headphones. Compact & Lightweight The design of the ITM05 is an essential aspect of its conception. It can go everywhere with you without taking up too much space, it has a reduced size of only 5 x 5 x 1.2cm for a weight of 23g. The DAC can be attached to the back of your smartphone with silicone and sponge adhesive strips to make you forget it’s there.
