I have heard the W5 with Siltech cables, and it sounded great. I don't know the models. If you want to try something warmer, I would suggest Cardas Golden Cross. There are a couple for sale today. Also Cardas Cross is a very good speaker cable, that is more affordable,very quiet,great bass and not at all bright. I used this combination with a Krell amp and Aeriel Acoustic speakers, and I think it did a great job of warming up the system,without overdoing it, and still allowing it to shine.
