Dac with build-up streamer

I have been reading about the Audio Analogue AADAC, the Bluetooth looks like it’s really good…so your smart phone is the streamer…it has a good volume control so you don’t need a preamp…anyone have any experience with it..

Bluetooth and a smartphone as a streamer???  No…just, no.  Bluetooth has limited bandwidth and smartphones absolutely suck as streaming sources. 

DACs are a very personal choice, and what are the odds that a combo unit has the best DAC for your tastes and a streamer with excellent performance and the user interface you like best?  I’d put those odds at close to zero and there will be a significant compromise somewhere.  Go with separates.
