What Class A is better? SUGDEN FPA-4 or PASS LABS XA-25

I listen that Sughen amplifiers in different models, the sound is  not that good. Pass is better.

@snapoli2 ...I’ve owned both, multiple pieces. I like Pass Labs allot but ultimately preferred the Sugden iA4 Masterclass - which I did not think would be the case.

Nice. Trust your ears with your speakers as you found out first hand. What sounds best for you? Try it if you can swing it. I like that Sugden Masterclass series too, had an eye on them myself a while back.. Growing up twenty minutes from Pass/Coda a’philes around me, and many found later there can be other options too. Sugden is a very cool throwback style design and parts inside.

In this case however, I’d likely pick the manufacturer or service-dealer closer to me when considering dealing with repairs, bias tune-ups, shipping heavy amps...bouncing around inside of shipping trucks. Had a few buddies getting stuff damaged in shipping lately. Another consideration in the decision making process, fwiw.

Between those two... Sugden with the right speakers, but Pass is more user-friendly as it can drive/sound better with a variety of speakers.

If I could add another option, Luxman L-590AXII. Definitely sounds better than the Pass to me.
