Very satisfied. AIO C + old hi-fi system = winning duo.
I am very happy with my purchase. Connected to my 20 year old hi-fi system, it completely modernises the installation.
The Triangle AIO application is simple, and the equalizer does the job. At the beginning, I paired it in multi-room with an AIO 3, but I sent back the AIO 3 because it was not at all up to scratch (sound adjustment problems, not enough treble). I'm about to buy a second AIO C streamer for a second room, and I'm going to connect it to a pair of active speakers.
