Speaker cable advice

I have a pair of older hollowgram 2 ...another option.Full meal deal.

I have Clear Day double shotguns in 2 systems,  if my memory serves me correctly Paul mentioned to me that he thought that the cables were better suited with tube amplification.

I also have a REGA ISIS Valve cdp/DAC. REGA OSIRIS integrated amp and new HARBETH 30.2 XD’s.

With the new HARBETHs, my upgrade path that worked for me just as you asked (warmer, more presence …) was to upgrade from an all NORDOST FREY cables loom to CARDAS CLEAR XLR ICs first.

The CARDAS CLEAR Speaker cables were the next to follow in good form but the largest impact was from the ICs.

The last piece in progress will be CARDAS CLEAR BEYOND power cables (demoed but not bought yet)

FWIW.

Aftermarket cables for headphones is an easy way to test silver vs copper cables. I've done it before and there is a difference.

The difference is slight, but it exists. If you wish to test it on your system..ask a dealer to loan you a cable to try out/swap between what you're already using.

The sound signature of a cable depends on more than just its conductor.
