PS Audio Delta 100


I have a PS Audio Delta 100 powering my Magnepan 1.4s. Looking into the construction of the amplifier by displaying Google Images, I find most Delta 100’s have different architecture than mine. I wonder how many versions are there? What was the company trying to accomplish by so many redesigns? The only online image of a Delta 100 that matches mine was found on a South Korean used hi-fi market site.

You could go on to PS Audio's website and go to "Ask Paul".  Ask Paul McGowan directly.  I feel sure he will answer your question.
I'm considering getting a Delta 100 to power my SMGa's. You have Maggie's. How the depth/sound stage with your PS AUDIO?
Thanks
Based on how many amplifiers ( and not just amplifiers ) I have owned in my lifetime, it is not uncommon to find different components ( capacitors, transformers, etc. ) to be exact, without a model change to the product, from companies such as P.S.Audio. Many companies are constantly looking to better a current design / product, or even trying to make it more cost effective without raising it's msrp. IME
