Here, a Samsung Galaxy S2 Tablet including a dedicated Samsung Docking Station. As software USB Audio Player Pro. This to stream Quobuz (access via Audio Player Pro) and listen to locally stored music (on a micro SDHC card). Via USB A to B (Audio Class 2.0) into Marantz 8005 DAC or DAC in the Cambridge AVR 751r or DAC in the Vincent SV-500 amp (depending with with rig I want to listen to music).
Big advantage for me with above solution: No additonal control required for streaming. Everything is done with the tablet lying on a small table next to the listening chair. Very convenient.
Alternativelly my DAP players whith above software (line in into the amps or via SPDIF into the DACs). In this case, reading glasses are a must for me 😏
I do not feel that I would need any tweaking. I’m happy with what I’m hearing.
