Andy Hefley designed the GAS Son of Ampzilla and Thoebe preamp after Jim Bongiorno left to start Sumo. This amp/preamp combination is still a formidable contender against today's multi-kilobuck gear! I am at this moment using this combination with a pair of DCM TW's (52779, 52780). Truly excellent sound!
Good SS Designers and their lesser known designs
Hi all
I am interested in learning more about very good amps and think one way this is done by looking at amp's designed by great designers first and then amp's that they designed but not under their own names.
1. Nelson Pass. Anything by Pass Labs. Question is what amp's by Threshold and which ones by Forte, as also which ones for Nakamichi and which ones for Adcom. Did he also do the HK Citation series.
Also, know the Nakamichi PA designs were inferior to the T'hold designs, how do the Adcom amps compare.
2. McCormack. Know he does the McCormack series and also modded a few other amps, Mac Mod 405 for eg. Any others.?
3. Jim Strickland. Did the Acoustat TNT amp's, believe also some Hafler TNT designs (not sure which ones), any others.?
4. Sanders of Inndersound/Coda. Which Coda lines and any others?
5. Other Designs/designers. Assume Muse belongs on this list as well as CJ MF series.

If you really want to learn about great amps, I highly recommend researching and building one. Watch the Burning Amp lectures. Read Nelson Pass's wealth of articles. I'm anything but an electronics engineer, but my understanding of amps has come light-years in the course of researching, building, and troubleshooting a Pass amp. Pass has dozens of designs that he's written articles on and explains well. Bob Cordell explains some older circuits well too. |
If you want to talk SS amplifier designs, I strongly suggest you look into the late Dr. Marshal Leach Jr. His 1976 paper, "Build a low TIM Amplifier" codified the modern SS amplifier and set the standard for designs for years to come. I write a little about him on my blog, here: https://speakermakersjourney.blogspot.com/2016/01/introduction-to-georgia-tech-leach.html Best, E |
