Over the years (not in order) I owned the Goldenear Triton 1 and the original Triton 2, Von Schweikert VR4, Proac 3.8. Triangle Genesis, Tekton Enzo, Tekton Electron, Snell Type B and a few bookshelves when I was in a small condo. However, in the early 90's I became very friendly with a high end dealer and heard it all, (in his store) Wilson Watt Puppy, Infinty IRS Beta, to newer setups.
Audiophiles try to come up with terms to describe what we hear, bass extension, sound stage, imaging, liquidity, etc. I guess it's like trying to describe what makes a woman pretty. The Electrons have all of the elements of a great speaker, bass slam, sound stage, etc. However, they just sound "good", more like what I hear at a concert. It's hard to explain, but it has the most "live music" sound than speakers I heard in the past.
Like I said, I did not hear the Double Impacts. They are huge, and my wife would have thrown me and them out. I called Eric at Tekton and told him my dilemma, and he decided to make the Electrons because of my inquiry. He sent the dimensions and a picture of the boxes as he designed them. I don't know if I bought the first pair, because I was holding out for a wood finish. After two months, I caved in, went to Home Depot, picked out a color and sent it to Eric. The Electrons were at my house 1 week later. The color is an off white and looks great. I can't imagine the Double impacts can sound much better than what I am hearing out of my Electrons. An absolute steal for $3000.
