@ Mr. MR

I was contemplating variations of SE output stage. Quoting Audio Note's Kondo-san: "The most significant mistake of theoretical audio maniacs in this century is that they threw away the OPT." My sims on OPT coupled MoFo however, show inferior performance compared to the LC as you designed. As a bonus, chokes are less fiddly to manufacture.

Of course I also understand that there are other issues when an electrolytic cap is used for signal coupling duty. One notable example being guaranteed messy incident on incorrectly installed polarity. :D

Seriously, I really am curious on issues related to LC output coupling I may not be aware of.
