Has anyone heard of these amps before?

At the weekend I met a guy that said he was the owner of Cornell Amps, he is a good friend of my G/Fs dad and used to do all of the electronics on his guitars/amps when they broke, and the business is in southend which is only around the corner from me.

I just wanted to know if they are known, any good and worth taking a look at (I don't particularly want to go there, try an amp or two, it ends up sounding crap and then I have to lie to the guy's face telling him its good)
