Dyna Mk IV Driver Boards

Hi,

This is my first post in this forum, and after after conducting a search, have a question for the Dyna guys.

I have a pair of Dyna MKIVs crying out for some attention. The driver boards are all stock, with most components looking past their best before dates. I've decided to swap out the driver boards, to jettison the 7199s and get the biggest bang for the time spent.

I've noticed 3 options out there, the Triode Electronics boards, Curcios, and Tubes 4 HiFi boards.

They're all in the same ball park price wise. Any positive testimonials for any of these? I've heard a bit about each but not enough to form an opinion.

I'd eventually like to use these to drive a system from 80 Hz or so on up, and live with them for a while. I'm not looking for a lush euphonic sound, but something nice, non fatiguing and natural but without being overly sterile.

TIA!

Dave
