Opinions On Concept

Hey guys, im thinkin about getting a new amp soon originally i was thinkin of a JBL 1200.1, but then i went to a local shop and saw the Concept CC-D1200, so they wanted a rediculous amount of money for it so i went home checked out online and i can get a Concept CC-D2400 for cheaper than that 1200 from the dealer. So have you guys ever had or heard Concept Amps, my idea is that with the 2400 i could poud my two tens to the max with 600 Watts a side ([email protected] ohms) and then i was thinkin of saving up some money and buying a Pure SPL sub, then i could bring the amp down to 1 ohm and throw 2400 Watts at. So what do you guys think of concept. Thanks for any Info.
