Excellent and nice choices! I feel the same way about the Revel F208 speakers I bought a while back. Completely didn’t need them since the Revel F36 were already pretty good but oh was the improvement noticeable. I honestly don’t think I will replace them as long as the are working properly.
Considering how shitty flying economy is in general, it seems like a 2 drink minimum is need to even tolerate it.
