@hshifi - got one, lovin’ it immensely.
12 days sounds about right, I felt like returning it after day 3. Then I left it on at moderate levels while my wife and I were at work, all day for the next two weeks (I had a month to return it, so I wanted to give it every chance).
- I have a Datasat RA-2400 (2 x 400W) power amp
- HDPlex 200W linear power supply that branches off to power a server computer.
- non switching power supply for the DAC
- wall warts power supply for the Synergistic Research Master Coupler X2 with a 20A C-19 plug to power the PSM156
- a small TV I use as a monitor
Immediately the noise floor lowered so that I could hear not even a slight hiss in the speakers. I have not bothered to remove / replace each component into the Furman PST-6, to see which device it improved the most.
I was looking at the In-Akustic filter (more expensive) before a fellow Agoner gave me this great tip off. I will admit that I wasn’t overly happy with the resulting sound at first, however it’s a great asset in my system.
I was looking for a power supply that didn’t limit current, which would affect dynamics, did have circuit protection built in, and this has a DC filter as well as what hshifi has mentioned.
I have lost absolutely no dynamics, the noise floor has gone dead silent, attack and decay are more pronounced, voices are more holographic and the mid bass is now even more palpable.
It is the device that answered all my desires, and delivered qualities that I hadn’t considered. It is a hifi bargain product. The biggest complaint I’ve read about on this forum was loss of dynamics using a power conditioner / filter. This thing leaves the sinusoidal waveform from the incoming power intact, and shunts (shorts) the high frequency hash to ground, well shown in videos. After initial break in, this device has shown no downside, and proves to be a valuable asset that punches hard for the investment.
a big ++ to hshifi
