Hello, I went from a .5 meter Wireworld Starlight usb cable to a 1.8 meter Furutech Formula 2. I just installed the Formula 2 and really really like it a lot! Everything got better sonically right out of the box (highs to lows), high end resolution and clarity, more bass weight and "meat on the bones." This usb cable immediately made the biggest positive improvement of any cable I've purchased. The Formula 2 is causing me to wonder how other Furutech cables measure up against the competition. And I'm a person who never gushes about cables, quite the opposite. I've more often than not been disappointed in the performance of many cable purchases I've made (speaker cables, interconnects and power cables included). This one bucks that trend. I can highly recommend the Furutech Formula 2. (Using Macbook Pro to Rega Dac)

I never heard about the Formula 2 until it was mentioned in a thread. Tried to research it and found very little, but did see one review by Whathifi. They loved it so I tried it. It's really good. By the way, I'm definitely not saying it's the best in the $100 range, I don't think there's ever a "best." But it's the best I've had here and improved the sound coming from my speakers.

I tried a few cables. Then demoed a ridge street audio USB. It was and is awesome. There is a trial period so you can return if you don't like.

I'd love to consider one of the Rigdge Street audio cables, (respected by people who should know), but my opinion about certain products in the mid and high end is that I'm just not willing to spend that kind of money in my current income bracket. It's tough enough spending in the $100 range for a usb cable.

I think you'd be hard pressed to find a better USB cable then the Wywire Ltespeed in your price range.
