upgradeable dacs


I am tired of wasting money on buying dacs to have them be usurped by new technology within a year of purchase. many dacs that claimed being upgradable either were not, or were so expensive as to be not worth it. (original berkeley and bel canto come to mind) Other than the new nad dac line which i think really can be upgraded, does anyone know of higher quality dac products which can be upgraded without any nonsense? thanks

The mid and high line of SCHIIT products have upgradable DACS. I do not own or have heard them. From my research they would be more than worth a look see. Good hunting. Post your results.

Empirical Audio Overdrive SE can be upgraded: USB interface, Master Clock for USB interface, Coupling Capacitors, separate power supply chassis and 13 internal regulators. It has already seen all of these upgraded over the last 2-3 years. Since it can drive amps directly, a transformer buffer stage is available to add-in other analog sources as well as bal-SE and SE-bal conversions.

Overdrive has been in reviewer and customer shootouts with all of the DACs mentioned, as well as Debussey, Weiss 202, PD MPD5, Emm Labs, Ayre, PWD, Metrum Hex and others.
