mep,
I don't see how a DAC can be "obsolete". Sure, better DACs can come up, but so can better amps and better turntables.
And as far as DACs go, the MSB is fairly future proof, being capable, today, of 32/384 (and 2xDSD), and being theoretically capable of Mhz speed.
Just as an example, the MSB was retrofitted with DSD capability with a simple software upgrade, totally free to the end user.
