I hardly think so, you get a great mic preamp, one of the quietest around, solid rugged unit and it will last you the rest of your life.
Quiet preamp yes, rugged unit yes, last you the rest of your life...well...I kind of doubt it. Not that I doubt the reliability of the unit, but what happens if another format like DSD or its successor really catches on? Seems unrealistic to think PCM will really remain the dominant format for a lifetime.
Edit: Look at the usage and desirability of "vintage" mics today and the usage and desirability of "vintage" recorders today. It sure seems like mics tend to hold their value and utility a lot longer.
BTW: About the mic thing, once you spend more than $500 on a pair of stereo mics, you are in the realms of the last 5% of variability in performance. Today the first 90-95% of greatness happens in the first $500 from my experience.
Are you seriously suggesting that one reaches a point of diminishing returns faster with microphones than with recording devices? Wow.
Edit: I don't deny that $500 worth of mics can sound very nice. But to suggest paying almost 5x that on a recorder while sticking with $500 mics, again, wow.
