Adromada III or sumo nine

I had a 9 a rep left with me for a while when I was thinking of carrying them, I remember that I thought it was a good amp at the time but it was so long ago I can't remember much else except I thought it was well built for price.

Been a few years, but the Nine had better sound quality than the Adromeda. Doesn't have as much power of course, but it actually was pretty decent if your speakers aren't power hawgs.

It was a balanced output working like a bridged amp usually does if solid state. For instance 10 volts out going to ground in a normal amp would be +5 volts and -5 volts on the Nine outputs. This potentially is good along with it being non-switching class A for sound quality.

I even used mine with some Acoustats for awhile. Had to be a bit gentle with volume, but within its power envelope it sounded good even on the revealing electrostats. It probably isn't as smooth and grain free as modern designs, but generally was a musical amp.

maybe a bit late here, but i have owned the Sumo Nine. reviews i've read about the Andromeda have not been good, but the Sumo Nine is a well regarded, if quirky little amp that makes a nice sound. can be a bit tiring to listen to, but if you like detail then you will be in heaven. it'll double it's output into 4 ohms, so there's plenty of juice. i enjoyed mine for some years before upgrading. definitely recommended, but if you need it serviced...
