If you like the Benz Z’s sound, but with more frequency extension, I’d suggest sticking with Benz and trying the Gullwing SLR. A fantastic cart, with the fullness, "warmth" and sweetness of Benz, but with ample treble extension. The Benz LPS is like that too, but IMO, isn’t worth the extra cost over the Gullwing.
No doubt consider continuing with the Benz if you like it. Mike @ Sierra Sound is keeping the brand alive.
No firsthand knowledge of the Reed 3P, not sure if its character is more unipivot live or gimbal reserve? I prefer the SLR nude variety from Benz on Gimbal bearing tonearms and their wood bodies are magically delicious in the upper bass / lower midrange on uni-pivots generally speaking.
I suspect an Ebony LP at trade-in pricing would be the ticket.
