Tice Power Conditioners - Wow!
We used 2 sets of Power Block & Titans, Series II with TPT Treatment for years.
Not sure why the 10 year age was referred to, we used ours for longer and our friend bought them and currently uses them in his system to good effect. These conditioners are high quality transformers, which I believe should last a long time when feeding source components (like ours were and still are doing) because they do not have a big load on them and are not stressed / run hard.
Like all technology, power conditioners have improved - dramatically. We're using a Sound Application for our moderately high end system (Meridian 800 series digital front end, Pass XA-200.5's, Top Tier MIT Oracle cables, Shasha Series I speakers, CH Acoustic power cords).
The improvement was dramatic - my jaw hit the floor - literally, immediately after music I was intimate with started to play! Music became MUCH more life like. I would think this is system dependent, meaning it will allow your components to perform their best. But, if your components aren't up to the task (figuratively speaking) - the improvement(s) won't be as dramatic.
Hope this helps.
