Let me explain...
I am working (painting murals) at a very large home during it's remodeling, and I am configuring a quality portable playback system for use in various rooms.
The amps and speakers will be on a rolling cart, and rolled into the rooms were we are working.
The high-end client is reluctant to give me a password for his wi-fi, or even a "guest password".
My Sprint cellphone (Samsung Note8) reception is fairly weak, and drop-outs are often.
Plus I'd rather keep my phone in my pocket, rather than physically tethered to the preamp.
Blu-tooth distances can be more than 100ft, from my phone and that rolling cart.
I'm not very knowledgeable in wireless streaming, and maybe there's a simple solution I am not aware of. (besides pre-recording a portable drive)
I mostly use Spotify, or other online music services.
I'd rather not reduce the playback rez to reduce dropouts.. I'd like hi-rez.
Any ideas ?
