I'm using these speaker cables to connect my new Marantz NR1605 A/V receiver to my B&W CM10 tower speakers and B&W CM5 bookshelf (surround) speakers. I bought two sets of these 10' cables as well as a single 8' cable for my B&W CMC2 center channel. So far, I'm very happy with these cables. They seem very well-made. Granted, no one really sees them, so appearance isn't really a huge issue, but they do look very nice and add a professional look to my home theater setup. Plugging them into the back of my receiver and speakers was easy with the banana style connectors. When it was all said and done I spent approximately $1000 on speaker cables and a subwoofer cable. I didn't take time to compare what my speakers would have sounded like with traditional speaker wire. However, everything sounds great... whether that's due more to the fact that I bought expensive speakers, or that I invested in good speaker cables, I honestly don't know... Most likely, it's a combination of both. I did do a lot of research prior to taking the plunge in buying all these Audio-Quest cables, and audiophiles say that good speaker cables really do make a difference... and comparing prices of the Rocket 33 series to some of the super high-line Audio-Quest products, $1000 seems like a bargain for my entire 5.1 system.
