So, judging by your comments the Lyr is more energetic amp with the HD650s, and the LD MkIV by comparison is a little laid back?
I think the HD650 does love tubes. I've tried 2 solid states (Violectric V100 and Graham Slee Solo SGRII) and though the sound is cleaner, solid states are not as musically absorbing then tube amps with the HD650.
Energetic, yes(because it has more power to deliver). Dynamic, no, IMO.
I always have difficulties when terms "energetic" and "laid back" were use to contrast two equipment using different topology to begin with in how they differ in sound to a particular listener. I really think the Lyr and the LD MKIV does not sound the same and there is no parallel plane to objectively compare one against the other.
So, if I have to say something about the two to compare them to the best I can, IMO, the OTL have better and richer midrange than the hybrid Lyr. With the HD650 at 300 ohm/103 dB, dynamics could be only a function of how much source signal and how high your volume control is set to as the load is an easy load to drive. I doubt it if the much higher power of the Lyr have an advantage on normal listening levels. On very high spl levels, yes, until you fry the coil of the headphones.
FWIW, there's a very big community(myself included) that are very happy and satisfied using high sensitivity(96 db and higher, horns, full range, etc.) speakers and low power SET amps. Most if not all of us rode the conventional audio train(i.e. money pit) where big powerful SS amps, tube amps, hybrids etc and speakers using planars, electrostatics, conventional etc. are the norm. Speaking only for myself, when I heard the low power/high sensitivity set up, I had a paradigm shift, then I punched my ticket out and never rode the same bus again.
Powerful amps does not mean more dynamics as the amp is only one part of the system. My opinion only of course.
