Not so sure that "tighter bass" is a possible outcome from wires. Tight (or loose) bass is mostly an attribute of the speaker. Loose bass is most likely to happen with large cones having high inertia (mass), long excursion, and low impedance. These attributes are why you don't hear discussions of tight or loose treble or mid-range. Large sub-woofers are a prime candidate. Any planar speaker, and a headphone planar in particular, will have the opposite attributes: low inertia, short excursion, and high impedance. You can't tighten bass that isn't loose. If bass is "loose", because of the speaker, about the only thing that will tighten it significantly is to switch to an amplifier with a higher damping factor to control the cone movement. Higher damping would mean an amplifier with lower output impedance. If your amplifier has a damping factor of about 20 or greater and you still have loose bass, IMO you need better speakers. More amplifier damping is not necessarily better. There are a great many "musical sounding" amps with low damping factors. I tend to prefer them. They just need to be used with speakers that are well-behaved without being led around by the neck. Of course all remedies are futile if the loose bass is "as recorded". If you're listening to a recording of a guy playing a bass guitar through a stack of 18-inchers powered by a tube amp, well, get ready for loose bass.
With headphones there are other ways to achieve tighter bass w/ changing pads, fit or lesser fit of pads with cans, removing rear screens, use of bass control items such as dynamat, sorbothane, BlueTac, etc.
I left my tweaky cables brain back in 1977-1995 time frame going to DIY cables, Blue Jeans cables, and hung onto a few of the old 'audiophile' cables (that had lost resale value). But it came back in 2017, not from cans from Fostex, Senn,
Brainwavz, Audeze, MrSpeakers - but my favorites - HFM. The 4XX, HE-5se, (400 and 560 about 6 years earlier) didn't change, but the HE5-LE, HE-500, HE6se, HEX v2 all changed radically. I blind AB'd 3 of them (too many mods on the HE-500 prior to test to get usable results. and it wasn't at all close all around, not just the bass.
I can only conclude that there is something defective about their cables in those models. Many have complained about the construction and performance of those.
But as a general rule - yes audiophiles are too easily influenced by vendors, publications, dealers, and audiophile friends. Need to test, and make choices carefully and avoid the herd as it moves from one to another "best ever" - very often the most expensive.
