Pass Labs vs. Sugden

Look as a guy that's built many high bias Class-A amps, even a couple of water cooled ones, what I see is what I see.
And Pass is way ahead of Sudgen for an amp for any "driving condition", and above that again by the same measure is to me is Gryphon.

Sugden is not anaemic at all.

Read again, not the sound, what’s inside!
Even on Sugdens "biggest power amp", from 2006 the transformer and very thing is "anaemic" in comparison inside

Compare that to Pass https://youtu.be/Ytqk_9z0KMQ

Sugdens could be nice sounding amps for small 2 way to medium size systems for unit dwellers, even bedroom systems. They are not in the same "bruiser" league as Pass Labs stuff.

@georgehifi I always enjoy and learn from your posts. Have you done any comparisons between Pass and the others (Sugden, Belles, Clayton) that puts it first and foremost for you?

No A/B’s, but just looking at the internals, the Sugden looks to me like it could be a "anaemic" version of Pass amps, look at the transformer size, amount of output transistors and power supply capacitors.

There’s also a reason they are saying the Pass get’s hotter, even though it’s bigger heavier and got more heatsinking, it’s most probably because it has more "music making" Class-A bias than the Sugden.

Pass every day of the week.
