The picture of the recommended cable doesn't show the adjustable bass pots; does the cable come with adjustable bass pots?
It looks like Peter stopped using the stock JH Audio bass pot for something he thinks is better. [I'm not sure that was a wise move.] He does offer an adjustable option, but it is different (and maybe more of a hassle) than what you're accustomed to using. Maybe he would still make a cable with the stock bass pot if you ask. I suggest emailing Peter with questions or requests for clarification.

Here is the complete answer your question (from the site):
In early October we will have the all-new Eidolic JH Sirens Series
connectors in stock. These are custom designed from the bottom up with all beadblast aluminum barrel & nut, white Eidolic logo, ultra high strength insulator, and gold-plated phosphor bronze contacts. These are light-years ahead of any other Sirens Series connector in build quality and are standard on all new and backordered Sirens series cable orders.
No more adjustable bass controls. The 4-pin JH standard uses over-tuned bass combined with selectable bass attenuation (a resistor or volume control) to control the bass “boost.” With DHC, audiophile-grade resistors are hidden inside the termination
plugs. This design is our creation and sets the bass level using single, non-moving, precise part that is exactly matched between left and right channels and
will never wear out or break. The bass is set to an optimal 50% (50 ohms) setting, comparable to “12 o’clock” on the stock cable. We can accomodate requests for more or less bass but 50% sounds best to our ears (25%, 75%, 100% bass also available – leave a note during checkout).
Modular bass control system available. We have developed an exclusive six-wire SP OCC silver litz modular configuration that allows the bass resistors to be swapped at will.
We consider the 8-wire silver model the ultimate for minimalism & sound quality, but the 6-wire modular model makes minor compromises while allowing control of the bass.
This is ideal for if you have two or more bass preferences that you would like to choose from – and this package includes two bass adapters. This cable comes terminated in a six pin male mini XLR, with the choice of 4-wire short-length or Ultrashort bass control
adapters. Ultrashort is ideal for ultimate home listening while the 4-wire
adapters are great for use on-the-go, minimizing bulk around the DAP jack.
Choose 0%, 25%, 50%, 75%, or 100% bass levels for your adapters – just let us know in the order comments for the two bass levels and whether you want Ultrashort adapters vs. ones with a few inches of length.
