There are theoretical advantages to using parallel processors for D/A conversion which stem from a noise power analysis of the conversion process. Accuphase has used this approach for some time. The problem with attempting a retrofit or mod youself is that you do not have the advantage of precision matching of devices to ensure that you accomplish the objective. This approach is best realized at the engineering stage of development and implemented in a large volume manufacturing process. Furthermore, if you attept to piggyback processors you will load the power supply in an unpredictable manner. Finally, the latest crop of D/A converters are exceptionally linear and quiet; you would probably not gain ANY audible improvments anyway.You can read more about the noise analysis in Robert Harley's September 1996 review of the Accuphase DP-55 in Stereophile, so I will skip that here. While lacking in technical analysis this link might help a bit:
