A&K AK500N + Devialet

[amabrok]

I saw one in silver (silent display), cool design especially the builtin touch pad but not small. I was told it will be only available with integrated DAC which makes it not so interesting for Devialet and also partially explains the price.
I would like something like it as a digital source: well designed single box and all function integrated

I have Aurender X100L. It gets very close to what you mention. All in one box solution with excellent sound quality, built in SSD and HDD, ability to stream from NAS and no extra cost for built in dac which won't be used in case of Devialet. plus an excellent controller app

Where they really fall short is streaming from online services like Tidal, Qobuz, Deezer, etc.

My understanding is that they are working on integrating Tidal streaming hopefully early 2015.

Another option which is really leading in terms of online streaming capability is NAD M50. They seem to have every streaming service you can think of integrated in their all in one box
