Good streamer that does not need wi-fi or internet to play local files

any if the sequential model Bryston BDP series digital players.
You can play the digital files just with the proprietary BRYSTON remote sold separately.

Thanks and I figure that is similar to the USB port housed in some CD players that can be hooked with memory stick or storage for playing digital files sequentially. To that end, I think FiiO R7 provides a better music streaming / playback experience thru its own FiiO Music app in the "Pure Music" mode, which does not rely on active wi-fi, internet or bluetooth. The optional remote can be purchase to remotely control the music playing showing on the screen. The price point is attractive too as $700. Nevertheless, the sound quality is not as good as Node Bluesound UNLESS you use the balanced output, according to Darko. Well, for the time being, let me stick to the defective Ifi ZS for a little while longer and wait for the next revolutional gear to come up.

My Aurender streamer will stream my stored files with out internet, it uses an apple tablet to control it via bluetooth/wifi. 

I'd imagine most streamers that can interface with a hard drive/NAS can also do the same. most phones connect through wifi/Bluetooth regardless if there is internet connection or not. I'm sure there is exceptions but i cannot see why you would need internet to interface with a NAS other then for things like roon or other software that adds meta data etc from the net. 

I was confused. Wi-fi is a type of "internet" or "LAN (Local Area Network" too that is shared between mobile devices via hotspots and radio wave transmission. The difference in terms of communication standard is that Ethernet is IEEE 802.3 based and Wi-fi is IEEE 802.11 based. When there is power outage and ethernet is down, as long as your cell phone or other mobile device has active "hotspot", the LAN can still be kept functional and, consequently, the streamer will still be able to stream music via wireless LAN. Most of the music playing app is developed / coded upon ethernet / wi-fi.

Bluetooth (BT) is totally a different animal although it is also a wireless technolog. Wi-fi enables connection between the mobile devices and the internet / LAN, while BT connects and transfers data between two devices in shorter range via electromagnetic wave. Very few if any streamers actually develop app on BT.
