Who says cables don't make a difference?

@erik_squires +1! 

Of COURSE cables make a difference, always did - the question is HOW MUCH?!? 
$6000? - $12000??
Even when occupying the right income group, is seriously beyond my comprehension.
Even if they'd be made of solid Au - and assembled by Aeolian virgins, in a higher earthly orbit 💫 - or some such. 🤑

Your explanation really sounds jolly much off the wall. Seriously. 

Best be holding my tongue now... 🤫

+1 for sure - so long we talk ICs and SCs. 

As for power cables my jury is still out - since a LONG time, and more so since I use a PS Audio power regenerator for all my source components.
Tried, though not the mega $$$$ items, and found absolutely no impact. Zilch.
Maybe Levinson power supply designs 'are to blame'? 🤔

Well, 10k is already a pretty low input impedance for a power amp, less than that, rather unusual... correct me if I'm wrong. 

It is my understanding that with VERY low capacitance pre-to-amp interconnects, which the HPC is, and and an equally low amp-input-impedance, a resonance circuit (Schwingkreis) can be created, in the process may destroy the amp. 

Any experts might chip in with further detail by all means.

I just shared this post on a much older thread, but I think it is also of relevance here? 

So, yesterday I purchased a 3 meter Madrigal HPC XLR interconnect set (for peanuts 🥜 $173.50 ! ).

After having now looked at this helical planar construction (behind the connectors) it shows how incredibly delicate this cable construction actually is!
I had initially planned to chop it up, and make 2 or 3 shorter cables from it.
But looking at the construction made me change my mind in a chiffy! 🙄😜

So now instead, I tried these items between my ML326S pre and my PASS X350.5 amp, replacing my Transparent Music Link Ultra... what an astounding difference this presented!!! 
Now so much for cables making a difference! 

They do sound brighter, but also clearer, more open, and have more PRAT than the 1.5 meter Transparent Ultra set, - which by comparison are build like a tank!
A far less delicate construction, but truly well made, for sure.

Now, if ones system is on the bright side those Madrigal HPC's - might - just be too much of a good thing, but if not - wow, they sounds about as delicate and refined as I do not recall having heard e.g. listening to piano CD recordings of Beethoven and Chopin.
Addictive in one word.

Listening to badly mastered CDs... - it gets pretty terrible e.g. "The Best Of David Sanbborn" - so... by comparison the Transparent shows less of that - badness -, for sure.
So for now, I decided to keep the HPC set in my system, it just sounds too good, so delicate, so right - and this for a 30 odd year old cable! KUDOS to Madrigal of old!
And AGAIN, yes, cables DO make a difference in deed.

 PS: To note, those HPC cables are constructed to have VERY low capacitance and need an amp input impedance *minimum* of 10k ohm. 

Ok, so no problem with oscillating. ✔️

Those HPC 'cable guys' would have been Madrigal...
Water under the bridge, eh?

One more take for the rather even big difference cables can make - though there're no guaranties here AT ALL!
Its like a crap-shoot very often (most often?) really.
The off-shoot of a more lucky strike I had just a few days back - now some of my upstream cables I disliked as too bright /slightly harsh/digital... now sound really clearer and more transparent than some others considered 'warmer' / 'more musical'....
So, no question, at least in this here household, - cables do make a difference -. 
Seriously,
