I had the same question a short time ago. Don't really pay attention to them anymore, kinda eye candy. Bought mine 2 years old and they were (the meters) just there. nice to look at though. Mine is paired with a Benchmark LA-4 pre amp in a large room with Wonderful Tekton Encore special edition speakers. Just rock and roll 85 to 90db give or take. The amp is wonderful, as others have described it. For my purposes (that being rock and roll) a great deal of headroom is needed to be accurate. For those that are unaware, My Tektons LIKE a great deal of current,( not watts, Current) and that current is GREAT via the Coda 8 V1 that I have. I have a PASS X 250.8 in another system and love it, again, Rock and Roll. It delivers approximately 60 amps of current if that is the correct way to phase it. The Coda, I was told delivers 75 amps. Again for my purposes of rock and roll, you can really tell. No regrets with my Coda 8, just accolades! Very impressive AMP!!! Robert
