DAC- which way- oversampling or non-oversampling

[carlosfm]

Well, no. Diyers cannot agree. The industry seems to have made its choice. How many among the good dac or cdp produced recently are oversampling or upsampling and how many are non-os ?

And why did Betamax died, when it was much better than VHS?
And why do we buy and listen to CDs when vinyl is (sounds) better?

And why do they put crap-sounding preamps inside integrated amps, when without it the sound is way better?

Oh boy, where is this discussion turning to....

Have somewhere Video 2000........ same story

At the time Sony/Philips invented CD, and at that time the one of the design goals was to make a music-reproduction system with low distorsion and with OS you get lower distorsion-measurements.

A little earlyer there were also designed amps that went to custumers without any listening-tests, but measured wonderful!

Nowadays the real diyers listen more intense and listening test decide what is good or not.
Vinyl or digital, or whatever but trust your ears!

I'm wondering if the real issue is whether the oversampling filtering is done right, and not that it's fundamentally bad. There are many ways to algorhythm digital data. Perhaps the issue is which way to do it best, and as learning improves, maybe so do the proper algorhythms.

The Rakk dac, using relatively new DAC and input receiver chips, has been getting great reviews, and that is an O/S DAC. Perhaps the algorhythms are improving.

Seems, that there is another issue with non-os DAC- phase shift between L and R channels, because data is comming in streems in chunks and one channel DAC receives data a bit later. And due to that at 1 Khz shift is about 4 degrees, but at 20 KHz- 86... What can you guys say about that? This is question of chipset used or applies to all on-OS solutions?

Konnichiwa,

What can you guys say about that? This is question of chipset used or applies to all on-OS solutions?

Well, the ime delay between channels is about the same as experienced by a path difference of around 8mm between the left & right speaker. Of course, you position your head repeatedly with much greater accuracy than that, so yes, it could be a problem for you.

At any extent, most of the more commonly used Philips Chip's actually do not exhibit this phaseshift anyway.
