I go directly to SAX-500.2 In Europe there is the boom in low-average number of installations in the door, and good sounding Class AB, and stable to 1ohm would be ideal ... here is full of companies that have focused on this band many are so power Stereo RMS @4ohm Watt 335 x 2 power Stereo RMS @2ohm Watt 650 x 2 power Stereo RMS @1ohm Watt 1200 x 2 I was semi-joking. As the market is going, smaller and smaller amps are the wave. That is mostly being done by Full Range Class-D, or more efficient design of board and parts. So for Jacob to build a monster A/B amp, especially with FR class-D's approaching or matching THD of class-A/B and standard class-D technology getting cheaper, it would not make sense money wise to build a surfboard. The traditionalists like me are getting fewer and fewer, and do not pull the trigger on amplifiers as fast and easy as the younger or competition crowd. Money wise, it makes sense to probably not build much larger then the existing A/B's in the line up. Heck, the 125.2 is a strong amplifier as is, and can power plenty of daily driving sub woofers with ease, along with big mid's or higher power handling tweeters. But the 125.2 does not sell as many units as a 1500D or 100.4. That shows Jacob, there is little market for an even larger, class-A/B amp that is a current hog, has a large foot print and is more expensive to build then a comparable class-D amp of the same power output in mono that is cheaper to build and smaller of foot print. Many people do not understand that in most amplifiers today, the most expensive part on the amplifier is usually the heat sink. Again making it more cost prohibitive to build a big class-A/B amp that will need much more cooling then a class-D of comparable output. A constant in this business is the cost of materials continue to climb. To go along with the whole idea of smaller being the better direction, across the world, smaller cars are picking up more and more of the market. People are going to have less and less space for big power amplifiers. Which means amp companies need to squeeze out more power from less size. Something that is very difficult or very expensive. Alpine has been leading the charge with the PDX amps, but the seemingly unending feedback their noticeable distortion levels do not put them at the top of the market.
