AC Power Can Make or Break Your System!
The audio you hear from your home
entertainment system is essentially the incoming electricity itself, and the
typically violent storms riding the AC line and its ground is very detrimental
to the performance of your components.

The Flow-28 is a sophisticated,
luxuriously made and finished inline power filtering unit that eliminates many
common problems caused by contaminated electrical power lines. It protects
against distortion caused by ground noise, voltage spikes and sags, high
frequency power supply noise from other components in your own system, and
finally high-frequency digital noise emanating from processors and digital

Plus you’re never alone when you take your listening
seat; the residential AC supply is shared with other apartments, homes, and
businesses on the same utility transformer explaining why many enthusiasts find
their systems perform to a higher standard late at night and over

And while the Flow-28 is a star performer at eliminating common
AC problems, it does it all without restricting current draw in any way.
Furutech, known for its world-class Pure Transmission engineering, build and
finish, have done the tests and the Flow-28 does not interfere with current
draw. The AC-1501R EMI-filtering IEC input perfectly complements the remarkably
effective Flow-28’s ability to eliminate distortion. The FI-28R IEC connector
finishes off the package.

The Flow-28 Inline AC Filter lowers noise on
every component on which it’s used resulting in very natural and extremely fine
resolution down and through the utterly silent noise floor. It improves
soundstaging and imaging while creating nuanced high frequencies, an attractive,
engaging midrange, tight and controlled bass, with power and dynamics to spare.

ceramic particles and powdered carbon. Nylon and fiberglass are incorporated as
well forming an extremely effective, mechanically and electrically damped
