TDS "True Dimensional Sound" Black Box

I have had the AR TDS box for two months and I belive it works well on average recordings, DVD and satellite sourced sound. I never had a volume problem with my system since I match my equpment fairly well. It does take some of the warmth out of certain recordings and if there is serious listening to be done I usually kick it out of the system and remove the additional RCA's. Another pair of RCA's and just the fact the signal is passing through another device will degrade sound to some extent. But for casusal listening, movies and DVD perfomances that are ususally average recordings at best it works quite nicely. If your a purist and you have your great recordings to listen to you will find that it may get into the way. It works especially well when you listen at low volume levels since it restores the detail lost at low volume. I would recommend its usage and as you become more familiar with its sound and your souces you'll know when to use it. You can purchase it for pennies compared to the cost of a good system, it cost no more than a good bottle of wine. It's all for fun anyway you look at it.
