I can agree with you in one thing. Cables are like jewelry. But once you reach a degree of quality, any little improvement it is hard to justify or appreciate.I disagree ...
Unfortunately, and I wish the opposite was true.
Auditory memory and being able to distinguish between the differences a cable can make is foolhardy at best unless the differences are massive. The weakest link will always win I'm afraid to say.
Its not a bad thing though is ti?
Some will need to accept that that choices and evaluations they make are based on the cable being seen as 'jewellery' rather than adding any significant improvement to their listening experience.
Just like in professional sports we always look for magical gains ... Sometimes those gains are hard to justify and sometimes they are not.
However maybe not by itself, but one little improvement over a little improvement, they start adding, and end up with a noticable improvement.
I am also quite sensitive to treable. And while I do not own super expensive gear, I have friends who does and I can confirm Caldera sounds different in most amps I plugged in.I'm one of those doomed individuals who hears differences between passive components like headphone cables, interconnect, and power cables. Rarely are the differences very large, but in audio, even small sonic differences that push the sound in the direction of my sonic tastes are meaningful to me.
I use the largest copper cable I could find (a gorgeous custom built cable that I promised the mfr I wouldn't publicize because he doesn't want to produce them) and it definitely makes a difference. The Caldera's sonic capabilities are, if not infinite, wider than pretty much any headphone I've ever encountered. It always has something extra "in the tank" if I exert myself to seek it out. And so it is with big copper cables, which make a difference.
The Caldera also fully validates my addiction to multiple headphone amps. Once I got started in this hobby 5-6 yrs ago, I always had more than a half dozen amps on hand, sometimes twice that (it's now 8 or 9). Well, the Caldera's resolution is such that it easily reveals to me exactly what differences there are between this and that amp. It easily, authoritatively reveals those differences. Tonight I'll compare the sound of the Wells Milo and Cavalli Liquid Carbon v2, two of my three favorite SS amps (the 3rd being the V281). The distinct personality of each amp comes through so clearly with the Caldera.
I give credit to ZMF for many things. One of them is delivering resolution to my treble-averse ears in a way that shows me how glorious high resolution can really be (when it's conjoined with musicality/musical verisimilitude).
All to say the Caldera has a gread deal of upside. It always seems to go higher when I give it a chance to ... one of the hallmarks of a true TOTL amp.
Now rocking some nos tubes in the echo (cheapo amp) but I feel it's different with every tube.
Love the calderas <3 and love you all guys! I feel like ya are family
