Cardas Power Cords for DAC

Price and brand by themselves in a blind purchase is no assurance of success.

If you are happy with CARDAS already then the risk of a drastically poor choice within that brand is likely diminished.

Intuitively —- even within the same brand venue —I would get the best available within your budget for your source(s) with one caveat:  take it for a test drive first whenever possible .

Thanks @akg_ca  but I still don't know what the recommended Cardas power cord for digital source (DAC / streamer in my case) is.

There simply is no "recommended" power cord model. within CARDAS or virtually any other brand; .....unless .....it already came with the designated one provided by the manufacturer of the electronics.

It’s left to you to do the pedantic stroll down the Yellow Brick Road to AUDIO OZ by actual experimentation ...hands-on ....a swap-in and swap out in direct cord bake-offs.

There will invariably be contenders and pretenders among any brand that you select. CARDAS makes fine cables (I’ve had some models over the years in prior systems) but until you actually do a hands-on A-B shoot-out, how will know that CARDAS is even your best available pick?

CARDAS was good but not a winner in MY system(s) (emphasis added).

My take:

-- Stay in the CARDAS stable for now as the base reference point selected. Consider exchanging your existing CARDAS power cables if necessary as a first step. .
-- Go plug the best CARDAS model available to you within your budget strata into your DAC ; and
-- The power conditioner power cable would be the lowest model choice IMO. The power conditioner is a filter in the first part and invariably the least sensitive . especially so if you potentially lack dedicated power lines from the breaker panel.

 Use the power cord that came with the device that would be the correct one for it. If you feel the need to blow your money for nothing, there are many charities that could put it to better use. 

Agree with most everything @akg_ca  has stated, except this:

The power conditioner power cable would be the lowest model choice IMO.

From my experience, it's the reverse and one of your best power cables should be feeding your power-supply/conditioner.
