The T1 SE MK3 has good synergy with both pairs of headphones. I will say though that the K545 is better sounding to me than the HP150, but that is a comparison review I may put up another day soon. I have done several tests using both headphones with the T1, and the K545 is definitely the better option. This is the same result with the Fiio E12, and any other gear I have tried as well. The K545 is just a better sounding headphone. I have never owned the T1 MK1 or MK2, so unfortunately I can not do a comparison. One complaint I do have with the stock tube on my SE MK3 is that at times the bass can be a tad slow and loose. It lacks tightness and refinement across the bass regions with heavy metal music which is my genre of choice. I am also noticing that the treble is somewhat tizzy and lacking some articulation. It is a bit of a mess in the upper frequencies on some tracks. I am about 8 hours in with the DAC/AMP so far. Other than the couple things mentioned, the T1 SE MK3 is offering a good experience with my K545, although not mind busting.
Edit: I just ended up ordering the Genalex Gold Lion E88CC Gold Pin version. I will update my impression of the T1 once the new tube arrives.
Hey EVOLVIST, I posted the following above on the previous page. I am still burning it in, but I will say I am not totally satisfied with the stock tube. Out of the box, the T1 SE MK3 sounds good, but not amazing. Bass is lacking in tightness. It is just far too loose. Also, in the upper treble I can hear that tizzy and unrefined character. It is not as articulate as I would like. Soundstage though is fairly decent. Everything is nicely separated, and instrument location is easy to determine within songs. However, I know the Gold Lion E88CC I ordered will improve things drastically. I do wonder if the headphone amp section has been updated though in the latest MK3 revision. Tonight I decided to use the T1 just as a DAC, and connect my Fiio E12 to it to power my AKG K545. People may be surprised, but the sound quality was shockingly similar to when using the amp section in the T1 itself. The bass on the Fiio E12 was tighter, more detailed, and controlled, but in terms of soundstage the T1 was the winner. Everything was more broad, open, wide, and had that toe tapping character.
