Alternatives to Zetex DDFA
Are there any new designs out there that are closed loop and have similar stellar performance?
Unfortunately Zetex only supported the OEM market, and seem to have had much less success in that than was predicted -- my guess is that the big-volume Far East OEM audio manufacturers (home cinema etc) care more about the fact there are cheaper class-D solutions available than the fact that Zetex's is better.
Which is a pity, having designed the crucial low-jitter circuit circuits for Zetex we got to both listen to and measure the DDFA and were blown away...
