DAC and their chips

There are quite a lot of digital analog converters available for computer based music systems. For example, my main music source is all digital -- Apple lossless files playing thru iTunes on my iMac feeding a DAC, then a tube amp to headphones and speakers. One can debate which DAC is the best over and over. This is a table listing what chips are used in which device:

Super Pro DAC 707	CS8416	CS4398
Zhaolu 2.5	n/a	CS4398
Zhaolu	n/a	CS4398
7.2x	n/a	PCM1796
Rush	CS8416	PCM1796
Fubar III	??	PCM2702

The CS8416 is a Receiver that supports S/PDIF input at 192kHz max. The CS4398 is a 24 bit D/A chip.
