What would the difference be between the Triode Wire Labs Obsession compared to the HP Digital American for a PS Audio Directstream Dac? Would it be noticeable?

Hello Jim,
Both are superb choices for your PS Audio Directstream DAC.

The "Obsession NCF", with the crazy expensive FI-50 NCF series of connectors ($385 & up EACH!), has 20% more conductors than the already beefy "High Power Digital American".

The "Obsession NCF" will provide a bit more deeper bass response and a bit more airy & effortless highs, while still remaining balanced. Depth of recordings will appear deeper & wider, while still focused...

I hope this helps...

Cheers,
Pete

Thanks, Pete. That does help. I now see why you named it the Obsession :)

$700.  the main difference.  if you can hear a difference in a controlled evaluation, i will eat my power cord.  8)

I'm am not starting a flame war, but EVERYONE who has heard the "Obsession NCF" compared to variety of power cords could hear a distinct DIFFERENCE. As different as changing an amp or preamp or DAC!!! If you can't hear the difference between components, you would not hear the difference between power cords...

It's all irrelevant Doug - we all know that cords can't possibly make a difference in an audio system.

not trying to start a flame war either.  but, my experiences have been different.  and i also believe a competent engineer should be able to design a p/c that's as good as it gets - with connectors included - for less than the price of a single furutech obscenity.  i believe these products are marketed to people who simply like their stuff ludicrously expensive, regardless of sound.

i can hear differences between components. i can hear differences between $10 p/c's and $100 p/c's (if the $100 p/c's are good.)  beyond that, i am happy to say that if there are any differences, they're either too small to be relevant, or no better or worse, just different.  if my ears aren't that refined, thank dog for that.  i'm just after excellent sound,  not into spending absurd sums of cash chasing the unobtainable holy grail. ;)

if anyone has $1400 - or even $700 - and wants to buy a p/c w/that, that's their business.  and more power to them, if it makes them happy.  but i will stand by my prior statement.  it may make them feel better, but it won't give them better sound - imo of course.

ymmv,

My 2 cents worth... I've heard many different power cords over the years and never really had a difficult time hearing differences.    I DID have a more difficult time learning what sounded better (my system, my ears).   After I got a chance to use Pete's HPDA power cords, I decided to stop chasing that ever-elusive "best" power cord.   

Would i find the Obsessions sound even better?    Hmmm, probably, but the price difference can keep me in fine bourbon for quite awhile.

sorry, if there are meaningful sonic improvements in properly designed power cords, then there's something else wrong somewhere.  either equipment or incoming power, or something.

Doug - try an upgraded power cord on your TV. What you see will surprise you, then talk about how it can't make a difference on a stereo.

Cables are best designed by filter and transmission line theory.  It is the power that is wrong, not 'necessarily' the gear.

Todays power grids are sewers. The induction and imprintation of noise on the AC grid is continuing to degrade the waveform and unbalanced lines are going to be continuing to degrade in the future.  60Hz AC with a clean waverform went away at the beginning of the electronics age and went into the toilet with the advent of cellphone communication.

The only way to think of a high performance power cable is to consider it the first stage of the power supply, which in reality it is.

that's why i use isolation transformers and balanced power isolation transformers on my gear.

quite a few years ago, i noticed the improvement in the sound of my digital gear when i used a separate isolation transformer on my transport and another separate one on my dac.  i am not totally insensitive to power issues, nor am i totally deaf.
