If oversampling was removed would sound quality be affected?
An inquireing mind wants to know.
thanks

so the muse does not oversample?
it takes from cdp dig out then d/a not ovrsmpld then to audio out rca to pre.
so you hear what no ovrsmpl sounds like?
so the muse dac was a waste of money? and will not reveal affect of non oversampling?Despite of some expressed beliefs upsampling or oversamlling is basically the same thing that's called interpolation which is adding additional samples inferred from the original ones. The main reason for OS it makes it easier to design anti-imaging filters downstream of the DAC chip that suppress ultrasonic frequencies in the spectrum which are always there being an artifact of DA. A classic NOS DAC requires a steep low-pass filter and steep filters tend to negatively affect SQ. With OS the ultrasonics are pushed higher in the spectrum and can be dealt with with a gentle filter that has lower impact on SQ. Many NOS designs omit the filter completely as technically the speakers and human ear are low-pass filters, while true non-linearity in the ultrasonic range in amplifiers and other audio components downstream of the DAC can lead to audible inter-modulation distortions and this is the main issue with using NOS w/no output filters. So one's success with NOS also depends on the rest of the gear.
The Muse DAC I mentined doesn't have any jitter correction, so likely it will benefit from an external jitter corrector such as iFi SPDIF iPurifier especially when used with lesser CD transports.

Sorry . I thought you said I ALSO will need that all that spdif stuff for the muse dac. My apologies for the misunderstanding.What did I say that made you think that? It is a NOS DAC and it will let you get a feel of NOS sound as cheaply as possible if that's what you're after, however being a simple device it doesn't have any jitter correction circuitry, so using an external jitter corrector between the CDP and the Muse can improve the SQ depending on how jittery your CDP is, this has nothing to do with OS/NOS. I suggest you try the Muse first and if you like it overall you may experiment with adding a jitter corrector later. There are NOS DACs out there that will sound better than the Muse but they start at 20x the cost.
