DENAFRIPS DAC ---- Owner Impressions, Feedback, General Discussion, Questions and more....

@alvin1118

Thanks for clarification. Since 0.005% tolerance on the resistor is only enough to achieve 14 to 15 bits resolution are you randomizing the selection of the resistor network used every clock cycle in order to achieve higher bit resolution?

World Class DACs have close to 21 bit resolution above noise floor currently - so just wondering how you get close to achieve that? Having 500 resistors per channel suggest you might achieve 19 to 20 bit resolution with noise reduction from random selection among 512 resistors...

FWIW I have full confidence you have a world class product just curious if you have overcome the bane of Resistor ladder and R-2R DACs which has been bit resolution (due to finite accuracy of resistor manufacturing tolerances). The huge multitude of resistors in your design is a big clue to me that they serve a clever purpose rather than just a curiously high specification...

I have my credit card out of my wallet and ready....but I am a painstakingly technical buyer so I would like more info if you can share (hopefully this aspect isn’t a trade secret).

At those prices, the Border Patrol did really well!

Interesting but the set up is colored to begin with (no 7 inch woofer can do mid range properly) so I think the conclusion was simply what worked with the gear used. If anything the Denafrips might be more accurate since they heard exactly the deficiencies of that speaker....
