Navigate to passlabs.com and look at pics of various amps. While the XA series has the meter centered, all the pics of the AB series do not.
Which makes sense given Nelson's explanation of the bias meters.
"As a practical matter, this means that our X (Class AB) amplifiers are biased to dissipate roughly half of their rated output power. The XA (Class A) amplifiers are biased to dissipate roughly three times their rated output power."
