It will surely measure terribly compared to state-of-the-art current DACs, but certainly I’ve found some of the older stuff is simply musical and enjoyable. I have an ancient Meridian 566.24 DAC I quite enjoy (the DAC portion of the famous 508 CD player). I think it’s from the same era as your DAC. The more recent (still old) high end Meridian stuff is better (808, UltraDAC) - but it’s amazing how well that 566 holds up for simply enjoying music.
Tried an RME ADI-2 Pro "Black Edition", which measures wonderfully - and simply hated the sound. It was like sandpaper to my ears. I’m very much a Koetsu / SPU type of subjectivist audiophile, not a "clean & neutral, wire with gain" objectivist one. So take that for what you will.
But yes, I certainly believe that bleeding edge modern tech and exotic parts are NOT necessary to a musical DAC - and in fact, can move it in the other direction. But the mastering quality of digital material is still the main issue here, overriding our hardware choices. I simply find a better "hit rate" of good-sounding masters on vinyl. All of my Japanese CDs sound amazing, though.
Some might claim I don’t have a resolving enough system, or hearing nuanced enough to properly appreciate the vast gains of modern digital source. And I could counter with the fact that (in my mid 40s) I’m on the low side of age-related hearing loss for Audiogon’s demographic 
I like a warm and smooth, full-bodied sound, and yes probably a bit of roll-off up top. A lot of modern gear sounds just way too "tipped up" for me. ** also I listen at louder SPLs compared to most audiophiles, which is certainly also a factor in my preferences!
