EAR 834P Deluxe with Dynavector 20 HX H output Cart.

And to complicate it, there is the third option of combining the low output cartridge with an external SUT and the MM input of the EAR. It can make a big difference, but there is an element of luck as no one can really tell what a particular SUT sounds like as it will depend on the cartridge and phono stage used.

I don't know how much TdP had to compromise when he was hired by Quad to design the 24p phono stage, or whether the Chinese overlords substituted cheap components for those he chose. I can say that the 24p (designed some years after the 834p) is much nicer with an external SUT than with the built in transformers. Now that difference might be due to a change in loading (internal transformers 10Ω, external 1:15 SUT gives 209Ω).
