The Lyr + Bifrost is an excellent pairing with HD650 and with LCD-2. Contrary to what some folks say, I also think it sounds excellent with HD800, however IMO it does also still limit HD800's potential. It's a good sounding pair, no question, but HD800 can still do much better (Mjolnir for example.)
HE-6...that's a whole different route. They require substantial power and while a Lyr can drive them, they only drive them to the level of HE-500 or so. Mjolnir is among the handful of amps that can properly drive them, and most HE-6 users are using speaker amplifiers instead since they can be had more cheaply for more appropriate power levels. IMO, if going with Lyr specifically, HD800 and LCD-2 are excellent options still, but HE-6 is probably not a wise purchase with that combination. It'll work, it'll sound good, but ultimately it won't make them much more special than HE-500 at half the price.
LCD-2 synergy with Lyr is famous. And I feel it has amazing synergy with HD650 as well. I do feel it sounds fantastic with HD800, but if topping out with Lyr, I think there's a lot less merit in getting HD800. Mjolnir + HD800 is phenominal though.
On the other hand for HE-400 and HD650, Lyr could easily be end-game.
Since your question indicated you know that Lyr isn't "the best" for HD800 and LCD-2, but you wanted to know if it would be "good enough", I'd say, absolutely, yes, it sounds fantastic. It's just that there's things that sound even better.
