If that’s flat, I’ll take it all day.
At this point I’m more interested in listening to music than chasing marginal, system-specific differences. Blue Jeans cables let me do exactly that - and the $ I don’t spend on expensive cables is available for more meaningful upgrades.
And that is just fine. Nobody here is trying to convince you otherwise.
What Blue Jeans cables do well is remove themselves from the equation. Their cables are very high quality, very well built, and there’s complete transparency about the internal components and electrical parameters being used. Low capacitance, proper impedance, good shielding — no mystery, no “secret sauce,” and no attempt to voice the sound.
Others have concluded differently, in that they have cables that do a much better job of "getting out of the way". Most take the understanding that a cable can never add anything, it can only remove things. Preventing the soundstage to expand and masking low level detail is definitely a voicing.
Some expensive cables do sound different to some listeners, but those differences are often system-dependent and small compared to changes in cartridges, setup, or room. I prefer cables that are neutral, predictable, and not acting as undocumented tone controls. I have plenty of predictable ways to do that: tubes, cartridge loading etc.
Do you know this from experience? Or are you just guessing?
