You are welcome. Not sure what speakers you are using, but I heard the Sugden FBA 800 with the Wilson Benesch Vector speaker and it was a fantastic match. Also great with my ProAc Response D-40r
In all reality, they're two completely different topologies. Pass doesn't sell any single ended class A amps anymore. They're all push-pull which is why the XA-25 is a more muscular amp. That Sudgen is clearly a single ended amp.
