Sorry, my BDA served me well. All within a system that retailed at about $15K.
I say it depends on what one has in one's system at the time of consideration.
In my case I was using a 10 year old DAC and had speakers that worked well in my room with my current amplifier. I wanted a new DAC, one that was NOS, R2R, and had tube output stage. Bought a Audio Mirror Tubadour III. It made a substantial improvement towards the experience I was looking for.
It is more how long lasting the qualities a DAC has to it’s owner. Not how long a DAC holds it’s place in the market. I held on to my BDA-1 for 8 years. Bought it used, sold it for 2/3rds what I paid for it. A highly regarded DAC that provides the sonics one desires should last a person well beyond 3-5 years. The market value is something else.
