I have a Yamaha A-S700 Amp and Wharfedale Xarus 5000 speakers. I previously had a Technics SU-A900MK2 Amp. The Wharfedale speakers tend to be quite bassy and the Yamaha amp is reviewed as also leaning toward a relaxed, warm sound. Previously with the Technics, the sound had more high end sparkle. Im thinking the amp and speakers are probably not the best combination? The sound is high quality to me, but the bass does over-power the music sometimes. What do people think?
