La Figaro 339 vs Lyr for HE-500

[Wirbel]

I'm currently debating between these two amps for my HE-500. The price isn't a big deal, but I am definitely curious if the 339 is worth an extra $200 in overall performance. I understand both amps benefit from tube rolling, but assuming tube rolling is an option is the 339 is solidly better amp overall?
 
I listen to mostly metal, lots of different sub-genres. I'll probably pair the 339 with an HRT II+ and the Lyr would go with a Bifrost.
 
Would love some feedback, thanks.
 
Also open to any other options in this price range if there is a better unit I'm overlooking.

So what did you do ? 
I'm stuck with 2 too. Lyr & 339. 
What was your choice ?
