ADAM Audio T5V, Etymotic ER4XR, Sennheiser HD 598 with Burson V6 Vivid Opamp
V6 is the best opamp i have heard and I love how musical and natural it sounds, not loosing any details. The presentation is not too forward or fatiguing in any way, this is how hifi should be, I also have some ti and sparkos opamps (discrete).

V5i feels more of a V-shaped sound in my setup, it is laid back and not fatiguing in any way. Separation is good, and it fits perfectly for anyone looking for a laid back, relaxed and V-shaped presentation.
