I bought a 4ch
Elemental Designs back in 2002 and still use it today. At the time they were a very small and not so well known company making some very well made and clean amps for great prices. Think I paid like $150-200 then. Nicer, more power and cleaner than the RF, kenwood, sony

and other various amps I've had.
-No idea what the deal is today, but they are still around!
The 4ch I had was very much underrated, where I run a pair of front components and a single 10". Plently of power and punch for me while not being over done. Fits nicely under my F seat as well. Seems most comparible to their NINe.4 amp. Worth looking into.
Here's pix of the guts if you like
