That was easy

I had the i3 Integrated it was very nice but I needed more high current capability.

The original Edge Electronics company can be found at http://www.edgeamps.com/. Edge was sold to the current owner in 2001 by the original owner, Tom Maker, who now owns Maker Audio.

I believe the I3 was a foray into lower cost, Chinese made products. Quite different from their high end products.

I had to replace the batteries in my Edge Sig 1.1 SE preamp last summer and their new location is outside Detroit I believe. The original founders have sold but they are very much in business and can service all Edge equipment. They were extremely helpful when I spoke to them. I also have an NL 12.1 amp and its an excellent sounding hi power amp. Also owned a G2 preamp and G8 power and was very happy with the sound quality. The store where I purchased the Edge was a new outfit at the time and they were trying out a lot of very nice expensive gear we often only get to read about. The Edge amp was one of the favorites and one they decided to keep as a line.

Do you know something about the Edge's laser bias output stage, incorporating a 630 nm laser operating directly on the silicon substrate of the bias transistor?

How many years can works the laser?

Do you think there will be any reliabilities issues about
that original circuitry ?
