Inexpensive Amp for KEF 107s?

Thanks for the information. No, there is no KUBE, although I don't understand why one would need a subwoofer with these speakers as each one contains a pair of 10 inch woofers and I've certainly never felt they were lacking for bass. Even moderately turned up, you can feel the bass tugging at the back of your pants legs...
Here's an image of the setup we have: http://d1xw7fnq30zy05.cloudfront.net/uploads/image/image/592505/scaled_003.JPG.

How good/bad is the Crown XLS1000? It's been recommended to me in another forum...

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.

Ah, it looks like this is the kube then: http://3.bp.blogspot.com/-RYbR3kTlEQ0/TV3NQ46xDnI/AAAAAAAAATg/-IoYXjc3Fg8/s1600/KEF+KUBE+107+Universal+Bass+Equalizer+for+KEF+107+Reference+Speakers+.jpg Yes, we have one of those.

(My initial search for kef kube returned this, which says kef kube subwoofer: http://www.shopmania.com/multimedia-speakers/p-kef-kube-2-250-watt-powered-subwoofer-30979186)
