Inexpensive Amp for KEF 107s?

The 107 & 107/2 speakers are efficient and easy to drive. I used a Proceed Amp 2 (250 watts into 4 ohms with both channels driven) to drive KEF 107/2s with excellent result. It's a beautiful amp with a separate power supply for each channel. They are switchable between balanced (XLR) and unbalanced (RCA) inputs. You can probably find one used for $500. I have three Amp 2s and an Amp 3 that I'll probably hang on to even though I now use the larger Proceed HPA 2 & 3.

Are you using a KUBE 107? The 102, 107, and 107/2 Reference speakers were designed to be used with their respective KUBEs.

The 107 KUBE is not a sub. It's an active equalizer KEF designed instead of a passive R/C network for crossover transitions. According to the KEF manual, it's required for accurate sound. The 107 KUBE also permits tweeking of HF and LF response, but this can be bypassed. I use 107/2 and 102 KUBEs with Jensen transformers to convert from balanced to unbalanced to go through the KUBEs. I bypass the tweeks.
