Bob seems to be hanging his hat of acoustic room correction, because if there is one component likely to become obsolete it's the processor as technology changes. So Bob, are you recommending something like a Marantz 8801, a Classe SSP 800, or a Bryston SP3? Risk is relative. Upgrading the DAC in an Oppo is much less risky.
OTOH, worrying about obsolesce can lead to inaction and missing the goodies available in the present.
