From iFi Audio
If you have high quality or hi fidelity headphones you are going to need some power in the form of an amplifier to drive them to their true performance potential. You are also going to need an exceptional external HiFi Digital to Analog Converter or DAC to process your music files in high resolution to enhance your experience even further. The DACs in a smartphone, computer, tablet or audio player on the market are not designed for processing high quality sound. iFi audio has developed top of the line products to meet the various needs and preferences whether you are an everyday listener or an experienced audiophile.
The nano BL is a MQA compatible DAC and headphone amp that can be both portable or home based. At 285 mW max output power at 32R, it can drive almost any set of headphones without a problem. With it’s Burr Brown True Native Chipset, and added MQA rendering, you have even more file or format choices from MP3, DXD384, PCM384kHz, to DSD256.
With it’s S Balanced technology headphone channel separation is unchanged with load (requires balanced wired In Ear Monitors, also known as IEM, or over the ear headphones to benefit). Running a high-voltage Direct Drive Amp, the BL gets 3.5V into high impedance headphones making it suited even for 600 Ohm headphones. The built in iEMatch means it can drive high sensitivity headphones at 0.5V with a dynamic range that is virtually identical to that at "normal" output at 2V.
It is compatible with an Apple iPhone or Android smartphone and tablet, PC, Mac, desktop or laptop, and DAP (USB C adapter or cable is needed for some Macs and sold separately).
