Nice device-it removes digital artifacts and cleans up signal prior to the preamp. Balanced and single ended inputs and outputs. This device has no sound of its own added or subtacted from the original signal. List $1500. Selling price $600 shipped. For less than the cost of a good cable you could use this and clean up your digital signal and have a way greater improvement. It makes CD's sound like SACD's and will also improve SACD's sound. There are plenty of reviews online if you do a search under Ortho Spectrum. This device is rarely offered for sale and worth much more for what it does. I have plenty of feedback under the name Pugstub on Ebay and Audiogon. I am trying to raise money for a new preamp is the reason for sale.
