Ric Schultz at EVS sells essentially the same device. In addition to the description on the Audio Sensibility Site, you can check out Ric's description on the EVS site.

Both Audio Sensibility and EVS offer a money back trail period, so you can't really go too far wrong. They are also both very inexpensive (in audiophile terms), so you're not out a lot of money.
Give them a try and report back to us.......
BTW, I've bought products from both Audio Sensibility and EVS and I think both Steve and Ric do great work and offer good value.
