Manley Chinook SE MK2

What about adding a SUT? Was recommended by a friend it's a substantial improvement. 

Define “outperform “.

Di you mean”sounds better”, “quieter “, more gain, or what?

 By the way, if the Chinook is like the Steelhead, the gain stage is a tube/transistor hybrid cascode and is remarkably quiet with a very wide bandwidth.

"How does the PL differ in presentation?"

For whatever reason, the PL is more convincing/realstic. 

I don't know why it would make a difference, but the PL is all tube-MC gain and rectification. 

Manley and most others are FET/transformer gain and SS rectification. 

Not a "better" thing, just what my ears like. The phonostage I demoed against the Chinook and a couple others before I had the PL, is all tube. 

Tube gain is noisier for the "ear to the speaker type." 

Again, if the Chinook is like the Steelhead in its gain stage, it uses a hybrid cascode consisting of a transistor on the bottom and a high transconductance tube on top. This topology can develop tremendous gain, wide bandwidth, and low noise relative to an all tube gain stage and on par with most all SS gain stages. No SUT inside.
