iFiGO Bar Kensei Portable DAC/Amplifier - Full MQA Decoder, K2HD Coding, XSpace, XBass, 4 Digital PCM Filters, High-Resolution Audio Enhancement for Smartphones and Computers

Overall, this is a well made and extremely useful DAC and amplifier. Came with two dongles (one is for iPhone, which is what I use it with), along with a carrying case - nice touch! The unit itself is relatively easy to use, although figuring out the various modes, setting changes, and light meanings will require you to download the User Manual and take your time learning the set up options. The sound quality is excellent, and it translated everything in full detail, including MQA files. Even with the 6dB boost, it's not as loud as my Red Dragonfly DAC, but this should be plenty for most users in a variety of situations (note that I have not tried it with balanced 4.4mm headphones yet, only 3.5mm). A bit hard to figure out what all the lights and locations mean, but either way it sounds much better than the converters in your iPhone or iPad. Overall, definitely recommended for audiophiles.

Ottimo dac portatile suono perfetto

As some reviewer said, some kind of magic is happening inside this device. Everything sounds far better, Xspace gives music a wide sound stage, Xbass is addictive, K2HD does some magic to my old Mp3 files.I have a Fiio BTR15, Fiio Q3-MQA, Hiby FC4 and returned a Shanling UA4 because it wasn't a full MQA decoder. Finally took the plunge on the Kensei. I hear so much more detail with the Go Bar Kensei than all other dongles I own.It is loud when driving my Sennheiser IE100 Pro. The sound I can get out of my HifiMan Sundara when the volume is set to Turbo is incredible.The hardware itself is premium, heavy, and polished because is Japanese stainless steel. In yesteryear you could have said this is the BMW or Mercedes Benz of all DAC/AMP dongles. It is a quality product.If you have the money and want the best DAC/AMP dongle in the market, get it... Just a warning, it is selling out and backordered everywhere.
