Hart Audio Cables

The Audeze MM-100 comes with only a “2.5m (8.2ft) Single ended 3.5mm TRS to 1/4" TRS” cable (seen here). There are various ways to set it up to run balanced (detailed in this video), including, e.g., something like this $113 Fostex ET-RPXLR OFC Balanced Cable for T60RP Studio Headphones, XLR Connector (after apparently partially frying my Magnius amp by disconnecting a 4.4 mm cable from an XLR4 adapter while the amp was powered on‡, I’m leery of the multi-part options Zadius Tech links to). But the Hart Audio Cables modular system seems to be the most elegant and flexible, and not too dear. I’ve started with:

Hart HC-2 cable and interconnect Multi-Kit with Hard Case

• HC-2: 3.5mm TRRS Balanced Modular Headphone Cable, a 3.5 mm TRRS connector for the headphones terminating in a Mini XLR 4-pin connector that works with Hart’s interconnects; and
  
• Custom Hybrid Metallic Multi-Kit With Hard Case, which (roughly) includes:
• IC-2-T Threaded 3.5mm TRS + screw-on 1/4" adapter (to connect to an iPod, iPhone with Lightning adapter, Schiit Magni Heretic ...)
  
• IC-3 Male 4-pin XLR (to connect to the Schiit Magnius, Jotunheim 2)
• IC-4 2.5mm TRRS (to connect to the BTR5-2021 and ES100, and until it goes on to a new home, Pioneer XDP-30R)
• IC-6 4.4mm TRRS (to connect to the Sony NW-ZX300, Shanling M2s)
•  Hard Shell Carrying Case for all of the above, plus things like:
• TRRS splitter to use phone headset IEMs (like the Shure SE215s) with, e.g., the Heretic
• Other 3.5 mm to 6.35 mm adapters
• Apple Lightning to 3.5 mm Headphone Jack Adapter
• 6.35 mm (female) to 3.5 mm adapter

Assuming the cables are as high quality as I’ve been told, I’ll migrate away from the $20 generic cables from Amazon to:

• HC-5 Dual Senn[heiser] Balanced Headphone Cable for the HD 58X Jubilee, HD 600, HD 660S2
• HC-14 Dual 3.5mm balanced cable for Meze headphones for the Meze 99 Classics (and probably the HiFiMan HE400se?)
  HC-9 Dual 3.5mm headphone cable for Hifiman, Focal, Meze 109 / Liric headphones and more (Modular, Balanced Capable) for the HE400se and Meze 99 Classics.

All in, I’m looking at about a $200 total investment (including shipping) to connect everything I currently have, with a lot less clutter than keeping multiple cables around (like, right now, I have a 2.5 mm balanced cable, a 3.5 mm single ended cable, and a 4.4 mm balanced cable, for the Sennheisers, plus the 4.4 mm XLR4 adapter ...)

‡ Schiit service received it on the 11th, and after I prodded them yesterday, today says “[y]our Magnius is in the final stages of testing” Update: They shipped it August 6th, after replacing the “left channel amplifier IC.”
