Z565 are one of the best audio transformers ever built.

I found the Z565 to have a very characteristic sonic fingerprint. Even with radically different topologies. I built an amp with a pair, and then upgraded to an output wound exactly like a Peerless S-265-Q, but with taps 20, 30% instead of the OE 50%. They cleaned the Z565's clock, and I got another pair made for the 4E27 amps, and got those with 20, 30 and 40% taps.

Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
Interesting. At Electron One transformer tests the Z-565 had about a perfect square wave output and the Peerless had overshoot on the square wave test.
The Z565 are $190 a pair and the Peerless is about $1200 a pair if MagnaQuest still builds them.
Personally, I think the Dynaco A-431 sounds better than the Z565, but the A-431 are lower P to P impedance.
If the Peerless sound as good as you state, they are worth the money.
What you may discover at some point is that a winding house with an NC winder, and the winding details gotten from taking apart a transformer can make copies of anything that is put in their hands. I supplied an S265Q, and had them made in pairs a few times...:)
