I have build these DACs using AD1865, and a USB dac using PCM2906 and am really impressed with their quality, although i do have CS8412, 8414, 8415 and 8416 recievr chips yest i was wondering that are there any reciver chips of the quality of cirrus CS841X by Analog Devices or Texas INstrumnets (appologies for my ignorance) however i have tried searching their websites but I havent found any... reason is that companies who have made beauties like AD1865, or PCM290x must have receiver chips to compete CS841X series ans i would like to try them...
