Kef 107 vs 107/2

I have owned a set of the 107/2 since 1992, and compared the 107 and 107/2 in the same system at the time of purchase. I thought the 107 and 107/2 had a very similar overall sound, although the 107/2 was somewhat more transparent in the upper frequencies. Overall, I thought the major weakness of the KEF 107 was that it was a little dark, and the 107/2 reduced (but did not eliminate) that weakness.

While the MA6500 is a fine integrated amplifier, I have found that the 107/2 like a lot of power. My recommendation is keeping the 107s and upgrading to a more powerful amplifier --- the McIntosh power amplifiers with autoformers work great with the KEF 107/2, and I suspect would be a very nice match for the KEF 107. If you find that the McIntosh autoformered power amplifiers (which lean a little to the polite side) and KEF 107 are not lively enough, a Bryston 4B SST would also work well.

Thanks everyone. This is pretty much what I suspected.

last time i enquired about the 107 - 107/2 upgrade at doug brady's ( warrington ) it was £650 and doug was sayin the difference is not worth the price so i didn't bother

i have had my 107's for over 15 years and they still make me want to listen :)
i use meridian amp/preamp and the seem to compliment the kefs quite well

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.
