If you are referring to the mINT I brought this up in a thread some time ago ... here although you might be referring to the other higher power class D amps they do. You can get them in the UK ... here for example.
They certainly offer a lot of power. Trouble is that there are so many niche brands (esp in USA) that it's not easy to know if they are worth a look or designed for people who use a Ford F350 for going to the shops!
