Does anyone know what happened to SUMO Electronics?


I can't find them or anyone who might have bought them them online.

Thanks in advance.

Curiousjim…no problemo, and full disclosure (!), I bought a Freya last November and it's a fun thing that's great for tube rolling. Also Stoddard wrote a book (or made a book out of a book length bunch of posts) about his adventures in the audio biz…haven't read it but I might.

I have an original Athena and Andromeda from when James Bongiorno ran the company. After he left later versions may not have been as good! Sumo closed long before James died!

Jim's Sumo Preamp was the Electra... Rich May did some tweaking and the called it the Electra Plus, Rich May then did the Athena.  
Jason Stoddard tweaked the Athena and that was the Athena II. 
James did the Andromeda... bipolar outputs.  Rich May did the Andromeda II with Mosfet outputs and Jason Stoddard did the Andromeda III with Mosfet outputs... Jim would not use Mosfets in an output stage. 

Rich May did the Polaris amp version 1. There were two more after that but I like the first one better. Had it for 25 yrs and had transistors replaced twice. But it was worth it. A really good amp.
Rich run quite a high bias on those  mosfets in the Polaris. Might be why it sounded so good and I had to replace them a couple of times.
