If you do not like the sound of these speakers after 10 days of listening, then bring them back. However, your listening room lacks soft surfaces which will contribute to brightness. MP3 or compressed music sounds like crap through my B&K AVR 507 and did through my B&W CDM7NTs, so I bought a digital media server and burned my CDs using FLAC (lossless) and it sounds great. Music through an Ipod or MP3 player and headphones can sound fantastic, but in that case the medium is the issue - convenience over sound quality. MP3 and compressed audio is not and does not generate audio quality for listening through speakers on a home system; i.e., any decent brand discussed here at Audioholics or AVS. Also, your amp, while putting out 35 wpc, should be able to drive the B&Ws, but will not help them sound as good as they can. As a former owner of B&W CDMNTs (7s/SNT, CNT) and a current owner of the older series (CDMs in my basement), I can tell you that B&Ws are power hungry. The more power, the better they sound. They have a reputation for brightness and warmth. I replaced the NTs w/System Audios because the SAs are clearer, have a better range and I simply hear more music. That being said, if you are going to listen to different speakers, test drive them at home so you can tell how they will sound in your room, w/your equipment. If the B&Ws sounded great in the store, the question becomes what amp/receiver was driving them, what was the source material and were you in a soft and acoustically friendly room (likely)? If you are running your music through an Ipod then bring it with you to demo the speakers at the store. But the true test is in your system at your home.
