Best DAP available,
This review is from: Astell and Kern AK100 Personal MQS & Ultimate Portable Hi-fi Music Player -32GB of Internal Memory (Electronics)
Had this beaut for a while now, and it has grown on me with more use, and breaking it in with the earphones. Sounds fantastic. The impedance is apparently a factor with a lot of earphones, but I purchased a pair of sennheiser ie800, and played some 24/192 or 24/96 files through it, perfect. The new firmware download has a 'pro eq' setting, I think for improving the impedance issue with some sets. It also allows the ak100 to be used as a usb dac to output to a separate amp. I can report this works very nicely, although only through a usb 2.0 port.
There are several other firmwares that can change the sound signature to your preference.
I've listened to the larger AK120 (which has two DACs), and while the sound difference is slightly noticeable, this unit is far better value at almost half the price.
My only other gripe is that finding lots of 24 bit music files is harder thanI expected, and expensive! Make sure your collection is at least 16 bit cd quality, and you won't look back. (mp3s sound terrible on this!)
