Hifiman HE4XX or other HP for on the go?

[DuckToller]

Got the HE400i in January, no balanced cable provided. Just standard 3.5 and adapter to 6.3
Very happy with it, provided the HP amp has sufficient output. The iFi Neo DAC-Pre and Heaphone amp did not provide enough juice, even with balanced output. while the iFi iDSD Signature does, even single ended.
You may run there into a problem with Hidizs. OTOH that device is realy portable, the iFi is only transportable ;-)
4.4mm aftermarket cable I own now. Alternatives start at 23.99 USD
