which out of the 3 amps is best

I am looking at getting a new amp and I need some advice on which amp is probably the better choice.  I am looking at the MTX TA7801, USAMPS Merlin MD1D and the Cadence DCA1000.  I want to get the amp sometime this week so all the advice that I get from you guys will be appreciated.

Run away from the MTX, it's not even in the same class as the USAmps or the Cadence, and the USAmps is almost not in the same class as the Cadence. USAmps used to be a much better product than it presently is, but like HiFonics, Alphasonik, Orion, Rockford, etc... They've seen better days. That being said, (and in case you didn't figure it out in my cryptic description above) I'd personally choose the Cadence amplifier over either of the other two.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

It was hard riding around with out any music but I have decided on the Cadence with the help of you guys.  I know that I will be beating hard.
