[QUOTE="BnGRacing, post: 7461617, member: 557400"] Mitek purchased Xtant and ruined the company. Having owned almost a dozen Xtant amps (pre-Mitek) and EQs in my days, there's absolutely no technology shared between the two companies. The old Xtant amps are actually very similar to the old PPI art amps (same designer). They're more robust but less user friendly. Personally, I like them a lot better than the PPI stuff. When Mitek purchased Xtant, the model numbers had a letter before the number (X603). These amps were not reliable at all. The lower line Xtant amps, a-series, were repackaged MTX amps with no thermostat controlled fans. Just a heatsink on one side. There's no 'cooling technology' to sell. It was a row of fins with a fan blowing on them and these cooling systems have not been used in any Mitek product that didn't have an Xtant sticker on the chrome.

Guess which is which. One has bipolar output devices and the other used MOSFET outputs. Guess which is which. They look similar, but they're not... [/QUOTE]
