Mathew; its more of there pro line/I believe you have to call them. The AT3007, as the numerals imply is a 300watt per channel X 7 and sells for about$4,000. They also offer a AT3006(6channel), AT3005, AT2007(a 200watt X7 channels for around$3,000 and on down to 2 channels both 300/200 respectfully.. These amps come with a 7year warrenty and some, like the 2505 require a 30amp, hospital grade recepicle due to extreme power draw. If interested, givem a call. They also ofer mutizone amps and a really nice mono amp that will eat those Marantz amps. Its design is, as I recall, the same as found in the 1506/1504/1502. Those 3 amps are mono modules from this amp. I recall the price on those ATI mono amps to be under $500 and they are a heafty $300 watts each.
