Does what it's manufacturers say it does.

None so far.

The one thing I'm not is a tweak freak. I tend to resist most 'tweak' hype. After all, if it were that great my equipment's manufacturers would have already installed it, right? Wrong!

Having just installed a passive preamp to simplify my system, the last thing I felt I needed was another network between me and the music. But, inspired by the recommendations of noted sound engineers, I bought the product from Audio Advisors. After all, I had thirty days to try it and could return it if I didn't like it.

I installed it and knew at once that it wasn't going back. The improvement was nothing short of phenomenal. The music sounded three-dimensional in a way I'd not heard before in 35 years of audio interest.

I experimented, removing the TDS from the system. Immediately, everything sounded flat. I couldn't reinstall the unit soon enough!

My advice: contact Audio Advisor, order a unit and try it in your system. If your system's set up right, I'm sure you'll love the way TDS makes it sound.
