Astell Kern A&norma SR15 is part of the new a&Norma line, a dual dac, high res music player, replacing the AK70 / AK70mkii. The design uses an innovative tilted screen and the SR15 features a new, upgraded operating system from the flagship SP1000, running from a quad core processor. Everything runs much quicker and smoother, with fewer steps and a nicer interface.
Sound quality is consistently fantastic - clear, effortless, dynamic and easy to listen to for hours on end. A great upgrade from a phone, whether used with earphones, headphones, into the car or w/ powered speakers.
The SNR of 122 dB and Crosstalk of 137 dB specs help to illustrate how clean the analog section of this music player is - those are excellent specs for any portable or home music player.
SR15 has 64 GB of built in memory and you can supply a micro sd card up to 400GB. SR15 uses new MasterHiFi Dual Dac chips - 2x CS43198 - for top of the line specs and to provide sterling sound quality.

Headfonia.com: User interface is snappy and intuitive... design of the A&norma is simply gorgeous... Sonically the SR15 impresses. It is a damn fine mix of musicality and technical performance. The soundstage is wide and clear. Resolution is top and imaging very good.
