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


I`d like experiences of the gurus.

Thanks

@facten  Thanks for the link I didn't know that site their reviews are really well written and professional. Cheers!
I have heard Pass and Sugden. A friend of mine owns both and prefers the Sugden, unless more power is required. I think they both sound very good, with the Sugden having a bit more clarity and the Pass more bass drive.

Looks like most comments here are from those who have looked pictures of the Sugden amps. Not a great way to determine how they sound IMHO.

Almost bought a Sugden power amp, but decided I needed more power and ended up with an Aesthetix Atlas to match my Calypso preamp.
