Update: I’m in deep wait mode for the Mesa, down to just the bedroom stereo which was never great so the upgrade bug is buzzing. Always used cheap WiFi or Bluetooth devices (Audioengine bifi, b1 andIFi Zen blue) to stream from my phone.
The new Exposure amp arrived and things had to change. Added an old Electrocampaniet ECD1 DAC ($700) and I’m using the audioengine’s WiFi streaming via optical connection. Huge, lovely musical improvement. With my subwoofer removed, plenty of bass. Clearly, in my system, none of the low cost devices produced the midrange and bass of the ECD1… now I don’t leave the bedroom. This isn’t healthy lol.
last: when streaming via Bluetooth (using Zen Blue or b1) it sounded a bit like pushing the loudness button on an old stereo. Sound wasn’t nearly as pure or sweet sounding (I actually like a DAC !) as when it was streamed via WiFi…
