IMPORTANT INFO RE: OPAMP ROLLING MINIMAX DAC
Sorry, the link is here - way too much involved in this... http://www.audiocircle.com/index.php?topic=86504.20 |
Doug's fav OPA2604 is available in DIP8 format so that it can be dropped right into the DAC without an adapter. This'll set you back the princely sum of $11, though, to obtain a vast improvement in SQ. Op-amp rolling in this DAC has taught me that equipment that has op-amps has no sound character of its own, independent of the particular op-amp in there. They make that much of a difference, IMO. -Mike |
The entire affair has become convoluted (in regards to the concept of reversing positions of Opamps in the unit) I made a mistake with the color indications in the article. Meanwhile, it seems credible concerns over reversing the positions of the Opamps threaten to overshadow the entire venture. I sense to forge ahead would cause unneeded headaches; I have re-submitted the article removing references to reversed positions. |
