oversampling vs. non-oversampling - what's the dif


Been lurking for awhile trying to figure out the best path for an outboard DAC unit. Units I've looked into thus far include the Benchmark DAC1, Bel Canto e.One Dac3, PS Audio Digital Link III, and the Altmann Attraction. However, one question lingers in my mind...

what is the sonic difference between oversampling vs non-oversampling?

-Manley Stingray (integrated amp)
-ProAc Response 1sc
-Nordost Blue Heaven cables
-Isotek GII Mini Sub (power conditioner)
-Denon DVD-757

On my system, wire changes cause major shifts in presentation. That said, OS and NOS differences, being active, exhibit night and day differences.

One visiting fellow, interested in buying my second pair of Scintillas, wrote me afterwards,

"Listening to the Scintilla and your DAC was a revelation."

The potential buyer brought some big tube output SACD player, an OS machine, to be sure.

Like all other OS pretenders before it, the oversampling behaved horribly, as I knew it would. Notes were simplified, decay shortened, stage is crimped. and tonality was thin.

The NOS, on the same passage, provided deep detail, great tonality, and endless decay.
To answer your question Shazam, there is no free lunch when it comes to great sounds. My gear has been highly enhanced by a genius audio electronics expert. It has been a long and complicated process, not to mention a turn of luck.

As for new NOS gear, I believe the very best is to be had from 47 Labs. You can google outstanding reviews of their gear.

For cheap thrills, look for a Scott Nixon, as Gmood suggested.
