I already have a software I like, DTS Play-Fi. It has been upgraded where it is now pretty good. I have whole house audio linked to various brands (Klipsch in my office, Onkyo in the mancave, DefTech in the dining room, paradigm in the kitchen and home theater, etc). What I really like about the software is when you have it installed on a PC or windows tablet it will stream whatever you are playing on your computer to any system (s) you choose. No USB cables, no hassle it just works.
The highest quality streamer in the Play-Fi ecosystem is the McIntosh MB50. Alternatively I can go with the Sony Signature player designed for this amp, the WM1AM2 with a docking station. The McIntosh matches the software ecosystem I already like and use, the Sony Signature DAP is designed to match my amp. They are both around the same price. Thoughts?
