I Disagree
I own the 107s and the 107/2. They do both sound similar, yet I prefer the sound of the 107s. They seem a little more coherent to me. The ability to biamp is all well and good and that is how I have my 107/2 set up. But to be honest there is really no difference in the sound or if their is it is not easy to hear. The 107s have exceptional bass control already (when used with the Kube). If you find the 107s to be a little dark, remember that the cabling used to connect the Kube via th tape loop on the preamp makes a significant difference to the sound. The 107s ans 107/2 are exceptionally neutral compared to most other speaker systems and I've owned many. They continue to surprise me with each upgrade I make in the chain. If mediocre components are used in the chain, then the end result will be somewhat mediocre. If cables are changed anywhere in the chain the results are immediately noticable. I am very familiar with the 107 and it isn't perfect, but its not far off. In other words I've heard better, but nothing yet that totally eclipses their performance. Properly set up; ie well out from the back wall by almost 4 feet - used WITH the Kube and with excellent electronics and cabling, these speakers will deliver excellent performance.
