I play hi-rez music directly from a local SSD as well. The significant change I made was shifting from using a laptop/PC/Mac to the ifi Zen Streamer. One of the primary reasons for this switch was to eliminate the audible fan noise that was present when playing music through the laptop. To address this, I opted to use the fanless MacBook Air, but unfortunately, the sound quality did not meet my expectations. Ultimately, I transitioned to the streamer platform and couldn’t be happier.
My question to you is, setting aside any electric noise and non-fortified usb port that might not be audible to you but could potentially degrade sound quality, were you bothered by the fan noise at all?
