Knowing typical Pass Labs class A push/pull amps the XA25 is 25 watts class A into 8 ohms and then goes into class AB for higher power typically about 70 watts. When Pass calls an amp class A they only give you the honest class A rating even though it puts out more power.
You will typically be running in either amp in class A almost all the time, only going into AB rarely on very short high peaks in classical music. If the XA25 is a newer amp it may be improved circuitry and sound better. Otherwise my guess is it's a side ways move.
