Even tried them through my Yamaha receiver. Same impression. The 325s, on the other hand, are punchy, lively and fun. Clarity and cleanliness of the music is just as present, as was the soundstage. The difference for me was in the liveliness of the sound. It sparkles. So, going against the grain, I’m keeping the 325s and returning the 650s.
