Hey Blackdevil welcome. I have not seen the 7900 offered on any sale. It is one of Outlaw's newer amp. I am an owner of the 7500 and this is a beast of an amplifier. If you are looking for a 7 channel then the 7700 will be a solid performer. The 7900 is for added power you really need. Know this that you need two separate circuits to plug this 145 lb monster to. You will also need larger, more power hungry speakers. The 7900 is a formidable unit and about as good as it gets in a multichannel power amplifier. Please don't anybody be sold on uber expensive $8k to $10k multichannel amps. A big waste of money you could otherwise use for a decent vacation. Spend that added money on speakers, a huge screen...perhaps a projector etc. The 7900 should be the best value for the money if ultra power is what you are looking for.

P.S. It will look awesome in your rack.
