Yeah, the 2D display of some of those cards was extremely fuzzy; nice and smoothed.
Video card anti-aliasing is not analogous to oversampling in audio though, because the video card has a lot of extra information it can use to apply the anti-aliasing. The video card issue is more like an ultra high-resolution source that has to be downsampled at some point; of course there'll be big gains when sampling at a higher level there.

Hi Earl,
I am thinking of upgrading my ACK DACK to the Perpetual Technologies combo.
Have you heard the DACK DACK?
I am looking for more dynamics but still retaining smoothness.
Any thoughts?
Thanks
Bob

Agreed!!
I have here with me right now two different players, one that oversamples.. 1bit 256fs...
The other UPsamples... 24bit/192khz
Both sound very different... its all a matter of taste (and manufacturer... and budget... lol)

The difference between them is not in the oversampling, since both do it. The difference between them is in the technology of the final D/A stage. It is the amount of quantization and noise shaping used at the actual D/A converter final stage. The 1-bit 256fs quantizes to a single bit and requires higher oversampling to distribute the quantization noise over a wider bandwidth, while the 24-bit/192k probably uses a 4 or 5 bit D/A stage with milder noise shaping. Single-bit 256fs converters cannot achieve 120 dB SNR, while the multi-bit converter is capable of the 120 dB SNR (20-bit performance). There is no monolithic true 24-bit converter in players today.

I have to second your thoughts on the 963SA.
I find it to be very non involving, The upsampling smooths out the jaggies but in a "processed" sort of way.
That is why I am using it mainly for DVD's these days and going the Modded CD25 route for Music.
The RAM CD25/MPX3 combo is creamy but Natural (kinda like Haagen-Daaz)
