Clayton or Pass Class A, which one do you prefer and why ?


Depends on speakers and preamp too perhaps ?

Mitch is correct. Wilson Shen, owner of Clayton Audio, is now serving customers directly.  He can be reached at:

I'd go with the Pass.

If you know anything about heat dissipation on heat sinks, the top mounted ones on some Clayton models are a not efficient at all for removing heat for Class-A heat dissipation.
You need vertical side mounted, and as many fins as possible. (thickness of fins are not important) surface area is.

I’ve made many very large pure Class-A amps >100w that heatsinks were not an option to use, as they would be as big as a coffee table.
I used a water cooled heat sink which was far better and cycled warmed coolant, through a slow fan cooled small radiator very effective but a very complex amp.

Can you tell me more about that? Did you ever consider full immersion cooling?
