Massdrop x THX AAA™ 789 Linear Amplifier & iBasso SR1 What do you guys use w/ your 789?
LuckyLuke575, austriandude, and 4 others

I use the SR1 with a JDS Labs Atom :) top combo!
I use a ton of different headphones and IEMs with my THX AAA 789 amp (paired with a Topping D50 DAC) but the ones that currently get the most play time are my (modded) Sony MDR-Z7, HiFiMan Sundara, Campfire Audio Andromeda, Massdrop Plus and Sony MH755, an $8 wonder that I modded with female MMCX connectors to get rid of the stupid J-cord and give me different cable options. It's a hell of an amp that's made all of my other amps redundant. It's just that damn good.
This is an old pic, but I thoroughly enjoy using IEMs with the 789. They sound perfect with the Solaris and it bums me out I haven't found a portable equivalent that gives me the same listening pleasure as this amp. These days, I have it paired to an SMSL SU-8 (balanced interconnects and output) and it just does everything right with my IEMs and has a perfectly black background even with the typically hissy and reactive Solaris.

Good to know, thanks!
Yeah you’d said that you needed a portable solution or something like that.
I skipped it because I own a Yamaha A-28, I mainly passed the offer as they up the price $50 without any improvement. THX hype is working its magic.
I'm feeding mine with an SMSL SU-8 DAC and listening through a pair of Monolith M1060 headphones. I really love the combo. Sources are Custom built PC via USB and a Mac Mini via Toslink.
None because am broke !
Sennheiser HD 800. It's so transparent that: a) it is unforgiving to poor recordings, b) one could tell apart different DACs, c) soft classical music are nice, but full orchestra feels a bit harsh.
Mine is currently being wasted on a pair of Nighthawk's and Fidelio X2...neither of which need much power. But my balanced Argons should be here in about a month!
