The absolute "best" filter/conditioner for digital

i use a ps audio dectet as a filter for my transport and dac.

i'm satisfied with the results. however, choose your power cords after a careful comparison of candidates.

Mrtennis I appreciate your power cord advice. It confirms what my experimentation has shown. My Grandfather was a Mariner, and my close cousin is Port Captain in one of the major eastern ports. Mariners say there's a place for everything and out everything in its place. This is probably a good rule for us--it's just to find the perfect place.
I'm laid up after shoulder surgery and will be doing experimentation with what I have when pain is reduced.
These forums have been a great value to me over the years and your input is appreciated :)

I use Monarchy Audios regenerator for my digital and at the cost of a "Good power chord" it wokrs great. I alternate it between my Transport/Dac as well as TT and have found it the best option so far. when used only on digital, on my system it improves the amps performance also and the only reason i could think of was it block some o the digital grunge from getting back into the main power.

If willing to pay more APS used to be great.

I found these to be far better than Filters/conditioners.

April 23,2018. Enjoyed the sound field and clarity of a solo piano from the best front row seat in a great venue yesterday. I’d like to update this thread as many new offerings have hopefully raised the bar. I understand a symmetrically balanced large isolation transformer is perhaps most efficient and best for “common mode” ac noise. I’m open to all new technologies as innovation is our never ending ally. I’m particularly interested in units/technologies addressing “differential mode” ac noise. Cheers! to silencing ubiquitous ac line line, both incoming and “within” our systems. Thanks for your contribution.
