I have to disagree with Cytocycle. Network cable is not something you want to use with the Rowland gear. It puts a load on the amplifier and it could cause you serious problems down the road. I tried MIT speaker cables and it was shutting my amp down. At the time, I was using the Rowland Model 2. After contacting Jeff Rowland, they explained (better than I am doing now)the reason for the problem and why I should stay clear of all cables that could add resistance to the equipment.
I must disagree with the "darkening" thing that everyone seems to put on Rowland products and Cardas Cables. One reason why many say the sound is dark is because of the high distortion levels their equipment is playing through their speakers (non Rowland systems). Rowland equipment is very low in distortion, so you don't hear the high frequency noise that most hear. It gives you the sense that the top frequencies are rolled off, but they are not. It's just smooth and silky like it should be. Cardas cables are great with Rowland equipment. I feel they neither add nor subtract from the Rowland sound. Check out the Rowland site and look at the measuresments of the equipment. The will give you a quick look at the good performance on paper. You have to listen to it to really understand just how good it really is. Of coarse, all of this is my opinion. I mean no harm or disrepect to anyone I disagree with.
