You mean 14-bit multiplexed D/A convertors and complex analog anti-alias filters?

Yikes, don't know anyone taking that route these days. Of course some are going with the much better 16-bit D/A convertors that came later, and throwing out the filtering altogether (along with 16-bit resolution), but that's hardly driven by the original technology. More driven by perceived shortcomings in the sound of today's technology, a perception I share.

DACs in general still suffer from jitter problems that can't be easily solved without a special purpose-designed interface. But it's just too small of a market for that to happen, so designers will continue to workaround the problem with various clocking schemes and adapted computer interfaces such as USB, Firewire, etc, most of which require jitter producing data and clock processing in the DAC. The best products available commercially or DIY will continue to use their own proprietary interfaces, as they have done for the last 15 years or so, usually only pulling data from the source using local clocks in the DAC to reduce jitter propagation.
