That latest talk I've heard about good pairings is with the Abyss TC.
But it is totally a veteran amp and it was only the tippy top right before Cavalli Audio closed it's doors back like 4-5 years ago.
It's got a very meaty sound to it, but still lots of detail. It pairs well with detailed and sometimes a bit dry or aggressive sounding headphones, and it's got gobs of power on tap.
I like it with my whole string of headphones, for whatever that's worth, but that's not like a "confirmed pairing" guide:
1. McIntosh MHP1000
2. HiFiMAN HE-6
3. Pioneer SE-Master1
4. JVC HP-DX1000
5. HiFiMAN HE-1000v1
