BSG Technologies qølPrice: $3995

Doug said: BSG’s qøl processing is not available from any other component in your system. If you upgrade from a $1000 amp to a $20,000 amp, you still won’t get the expanded and enhanced sound you get from the qøl. If you want this sound, there’s only one place to get it, and that’s from the qøl Signal Completion Stage.

Read the SoundStage! Hi-Fi review.

The gist: Whatever it does, Doug liked it, but it is expensive.
