Lexicon has upgraded their venerable MPX-100 to 24 bit AD/DA, and 24 bit internal processing. The new box is called the MPX-110, and has a slightly different paint job than the earlier unit. It has the stylish oval type design, which is all the rage right now. Kind of hard to find a product at NAMM these days that has right angles.
According to the Lexicon rep at the show, the only changes made to the unit are the 24 bit Lexichip in it and the 24 bit AD/DA converters. Otherwise, the unit is the same as before. Except the price. That has gone back up to a manfacturer's suggested price of $329, with an estimated street price of around $249. I believe that's what the MPX-100 was originally priced at, if I remember correctly. The MPX-100 is being replaced by the MPX-110.
