As I move my main audio system further away from my living room and into a much smaller area towards the back of my house, I began to turn my attention to streaming services over WIFI. All other solutions worked but I needed to accept low resolution. I found Soundberry Audio while searching for better equipment and came across the PA90A. Without getting into a full system review, I'll just tell you that this network streamer/dac/amplifier has transformed my listening. Certainly the best my system has sounded since I switched to streaming only. Sound is effortless and 3 dimensional and imaging is excellent. Well beyond my expectations
