The very first power conditioner on the market for audio use,The Tice Power Block did the AC>DC>AC filtering and if your patient can be had for a grand which would come with The Titan Storage block which holds 1850 watts of purified electricity. I heard immediate benefits upon putting in my system, deeper tighter bass,the music hologram expanded higher above my speakers. For the price it's a no brainer.
In the day the pair went for 2500.00 but you can find them used these days. I do not reccomend buying them and having them shipped because the rubber grommets that the transformers are attached to dry up. and break when shipped. You can replace the grommets by taking them out and going to a motor cycle shop to match and replace. All you need is a socket set to open unit.
George Tice was the grandfather of AC line conditioning and regeneration. The Tice PowerBlock uses a very large isolation transformer engineered to smooth incoming current and absorb and spikes and noise in hi-end audio systems. Using a unique feed forward / backwards design, natural power issues are equalized out. What you no longer hear is a layer of glare, grain and a veil of noisy grit and constriction of dynamics. All of those things that affect music negatively, simply erased.
The system also employs two 3/3 uf polypropylene capacitors to correct for out-of-phase current use.
The included Titan Energy Storage System is an upgrade to the Power Block. When plugged into the rear of the Power Block it forms a transient AC energy storage and conditioning system. By suspending energy in a 2nd huge, laminate core, transformer it generates a reverse electromotive force that supplies instantaneous power to the PowerBlock. Not only does it improve filtering and lower the noise floor even more, it will bump full current delivery to to 20 Amps.
