Just like with a lot of other things, bigger numbers are not always better. Today I found out that 1 bit D/A converters have better "resolution" (the digital signal is converted to the analog signal with a VERY small error) than the larger bit D/A converters. On the other hand, if there is a burr brown D/A converter, that can be better. But those have problems with CD-Rs. Anyway, save money and wade through the BS when you're buying your new HU.
