iFi Audio - Go BAR
DAC & Headphone Amplifier for On The Go
If you are looking for a small compact yet giant sounding amp for your harder to drive headphones then look no further. This GO Bar is made for the audiophile who demands good sound on the GO.
This was built by iFi to give you an experience like none other. They put a high current headphone amp coupled together with a 16-core XMOS micro controller to process the audio that is coming into the DAC to ensure you have the cleanest sound with the deepest bass, tight midrange and controlled highs.
The DAC can decode and covert signals up to Ultra Res level PCM 32 bit/384khz, and also plays back DSD256 Natively. All in that small little box! This is super impressive. It also does MQA if that's thing to you.
If that's not enough these guys below gave it there praises as well:
