I am interested in lossless music using headphones and my WiiM Amp. I am asking how people are using to using headphones with the WiiM Amp USB port.
I just need a reliable way to use a completely wired signal path from the WiiM Amp to my headphones.
Right now I am using:
WiiM USB Out ——> in-line DAC 3mm jack——> W&B Px7 S2e headphones analog input
The Px7 S2e volume controls in Bluetooth mode do not function in wired mode by design.
The DAC is a Fosi Audio DS2. I have two problems.
First, the analog audio output is unusually low. To get reasonable sound levels the WiiM volune has to be increased from the ~ 1 LED light I use with my Polk S4 speakers (91 dB efficiency) to ~5 LEDs. The Fosi has a bulit in amplifier which is set to 100% (128 mW). When I use the standard iPhone USB-C – 3mm dongle the sound levels are smilarly low.
The volume is low when I connect the WiiM USB directly to the Px7 S2e internal DAC (also USB-3). The audio output levels for all these configurations is normal using a direct connection to a USB-C iPhone.
When the Px7 S2e internal DAC (also USB-3) is directly connected to a USB-C iPhone, the volume level is normal. When the Fosi DAC is connected to a USB-C iPhone, the volume level is normal.
Second, the Fosi DAC’s connection the the Wiim is unreliable. When a signal is present, the headphones automatically switch from Bluetooth to wired mode. With the Wii Amp I never know if the initial connection or reconnections will work. The heaphones behave as though there is no signal. Eventually they will connect. But there doesn’t seem to be a reproducible way to make them connect and, or reconnect. When connecting an iPhone USB C port, the Fosi DAC always connects and stays connected.
These problems occur with all the WIiM inputs I use (internet streaming, MacOS Apple Music to WiiM via ethernet, WiFi and TossLink using an Apple Airport Express or Apple TV Gen 3 Rev A.
I have used different sets of cables and used cables with and without USB A to USB C converters to no avail
The WiiM Amp USB output spec is 5V. Unfortunately I don’t have equiptment to measure my Amp’s output voltage.
