"A historic moment"
The LS-4004 AIR Pure Silver tested in HiFi Sound & Music 02-2023
"When the desire for something new dries up, passion dies.
Or:
People who refuse to budge from earlier judgments, deprive themselves of opportunities for further development, and won’t really make any advances in high-end audio.
The pure silver cable from in-akustik teaches us this lesson in an astonishing manner [...]
"That which cannot be, must not be” is an outdated maxim.
Thanks to the upmarket LS-4004 Pure Silver, which proves even the most devout doubters wrong.
A new benchmark."
