After reading this thread, I'm very curious about the Midgards HALO tech at this point. I'm thinking of using my Hifiman EF400 for DAC duty and hook up to the Midgard using the balanced connections. Thinking that might have some serious synergy with the Himalaya R2R DAC onboard. I think my only other option for balanced would be the DAC built into my Monoprice THX 788 all in one which uses AK based dac chips. My Schiit MMB2 sounds pretty promising as well.
My biggest question, has anybody tried IEMs yet with HALO, do IEMs work well with Halo? Most of my cables are all balanced and I can do a XLR to 4.4 adapter which is pretty much what I have to do with some of my other amps that lack 4.4mm. I am also wondering about AMT headphones and if anybody has tried those?
Low gain on Midgard definitely works well with IEMs due to its super low noise floor and enough low gain and the synergy between the warmth of Hifiman R2R matches the neutral-reference signature of Midgard Halo. Not sure if you can run hyper low impedance Campfire Andromedas though (2 ohms at 20-100 Hz), but I think senstive IEMs that has a very low impedance load (6 ohms for example) but has LID implementation will work perfectly fine with Midgard on low gain. Grab some Furutech 4-pin XLR to 2.5mm adapter and you'll be golden
Keep the adapter fully balanced to ensure Halo is working perfectly. The cable has to be wired balanced for Halo to work . Also avoid any adapter with wire in between to minimize signal alteration and signal loss
