For IEMs, FiiO M15, HiBy R5 or Lotoo PAW S1 with HYLA Sarda, Z1R and EE LX (which I have sold and rebought a second and final time, haha). Cycled through quite a bit the last 2 years or so and I'm really happy with this trio currently (so much so that I am reshelling the LX and Sarda to Custom and getting some custom silicone tips for the Z1R), though the curiosity never goes away completely. This darn hobby is fueled off FOMO. Looking forward to get in on upcoming Sultan and ODIN tours. I went ahead and signed up for the Thummim tour after reading glowing reviews including yours, though I'm not sure I could stomach the price on that one!
