Adromada III or sumo nine

Just acquired a Sumo The Nine Plus (Revision C).
Wonderful sounding little gem highly recommended.
Sounds almost as good as the Levinson ML-2's I once had, delicate and detailed.
Do not try to service/upgrade it your self because it needs more skill the your average DIY'r.
Had perfect feedback from Mike Bettinger from GASaudio(http://www.gasaudio.net/index.html). Very decent guy superb communications. The Nine and Nine Plus are worth the investment of upgrading by GASaudio in my opinion.

Hi Brian_eno

Glad you are enjoying the Sumo amp you acquired. What is Revision C on the Nine Plus you have? Does that mean you have a 3rd generation Sumo Nine Plus? I don't think I've ever read anywhere about different revisions for the Sumo amps.

Mike Bettinger does great work on Sumo and GAS amps. He send me pics of the work he did while he was re-building my Sumo Nine and I was amazed. Very nice work. I'm contemplating a reference re-build for my Sumo but I really don't like being without it. Even in this summer heat I enjoy the music it makes. I did eventually get used to the fan noise.

Hi Brian,
Jason Stoddard is still around, he is a co owner of Schiit Audio. He was the head designer at Sumo when Jim sold out and did the conversion from the Nine to the Nine Plus. He would be available to answer any questions, plus full Schematics are available online. As much as I loved the Nine, My modded piece is sooo much better than the stock, I'd hate to discourage anyone from improving this amp. Mike Bettinger used to do parts upgrades on this amp himself, he may also be willing to do upgrades.

I have a polaris class a/b. probably more along the andromeda sound. Back in the late 80's I listened to both of them extensively and the polaris to me was had more natural clean harmonic structure such as in the overtones of a guitar. I kind of wanted a to hear a nine but never did. It is little forward in a nice way. Also compared it with rowland model 1 on theil speakers and a lot of similarities even though different because of mosfets and bipolars but the polaris was 90% of the rowland in that system to me. I know this is not about the polaris but it is nice to hear about Sumo's and know of potential upgrades. Thanks
