I would not assume that these DAC's are going to automatically mean better sound quality than a 24-bit/192kHz DAC. For one thing, there is no 32-bit source material and I can't find much online to explain what practical benefit the extra bits provide when dealing with 16-bit and 24-bit signals. For another thing, the overall design of the analog circuit is very important - two separate implementations of the same DAC can (and frequently will) sound different.
